BG Electrical 32A 4 Pole IP65 Rotary Isolator – Anthracite Grey | CPRSD432AG

Weatherproof Four-Pole Rotary Isolation Switch for Heat Pumps, Hot Tubs and EV Chargers

The BG Electrical CPRSD432AG 32A 4 Pole IP65 Rotary Isolator in Anthracite Grey is a robust, weather-resistant electrical isolation switch designed for domestic, commercial and light industrial installations.

Manufactured by BG Electrical, this contemporary rotary isolator provides a practical means of disconnecting electrical equipment from its supply for maintenance, servicing and safe working procedures.

Featuring a modern anthracite grey enclosure with a contrasting black rotary operating handle, the CPRSD432AG has been designed to complement contemporary building exteriors and outdoor electrical equipment.

The colour scheme is particularly suited to installations alongside the Sync Energy EV Charger, providing a coordinated appearance.

With an IP65 ingress protection rating, the isolator is designed to resist dust ingress and water jets, making it suitable for appropriately installed outdoor electrical applications.

Its durable enclosure also features an IK10 mechanical impact resistance rating, providing a high level of protection against external mechanical impacts.

The four-pole switching arrangement allows the simultaneous isolation of four conductors within a correctly designed electrical circuit.

This makes the isolator suitable for compatible electrical installations requiring four-pole disconnection.

A key safety feature is the padlockable rotary handle, which allows the isolator to be secured in the OFF position using a suitable padlock.

The unit also incorporates a lid interlock, preventing the enclosure cover from being opened while the switch is in the ON position.

These features support safe electrical isolation procedures when correctly applied.

For convenient installation, the enclosure provides four M20/M25 cable-entry knockouts, arranged with two at the top and two at the bottom.

The isolator also features captive cover screws, captive terminal screws and backed-out terminal screws, helping simplify installation and maintenance.

The enclosure measures 176mm high × 116mm wide × 136mm deep, providing a practical surface-mounted solution for exterior electrical installations.

Suitable for appropriately designed air source heat pump, hot tub, EV charging and other fixed electrical equipment installations, the BG Electrical CPRSD432AG Rotary Isolator combines reliable isolation functionality with weather-resistant construction and contemporary styling.

Four-Pole Electrical Isolation

The BG Electrical CPRSD432AG features a four-pole rotary switching mechanism.

A four-pole isolator is designed to disconnect four conductors simultaneously when operated.

In appropriate three-phase installations, this arrangement can be used to isolate three phase conductors and the neutral conductor.

Benefits of Four-Pole Isolation

• Simultaneous disconnection of four conductors
• Suitable for compatible three-phase electrical systems
• Practical for equipment maintenance
• Convenient rotary switching operation
• Supports safe electrical isolation procedures
• Suitable for fixed electrical equipment
• Useful in domestic and commercial installations

Typical Four-Pole Applications

Four-pole isolators may be specified for equipment requiring the isolation of three phases and neutral.

Examples include compatible:

• Three-phase electrical equipment
• Commercial plant
• Air source heat pumps
• Industrial machinery
• Electrical distribution equipment
• Building services installations

Important: The suitability of four-pole switching depends on the electrical system, equipment requirements and installation design.

Protective earth conductors must not be switched or disconnected by the isolator.

IP65 Weatherproof Protection

The BG CPRSD432AG features an IP65-rated enclosure, making it suitable for appropriately installed outdoor applications.

IP65 provides two important forms of ingress protection.

IP6X – Dust Protection

The first digit, 6, indicates a dust-tight enclosure under the applicable test conditions.

IPX5 – Water Protection

The second digit, 5, indicates protection against water jets.

Benefits of IP65 Protection

• Dust-tight enclosure
• Protection against water jets
• Suitable for appropriately installed outdoor locations
• Practical for exposed building exteriors
• Suitable for heat pump installations
• Suitable for outdoor electrical equipment
• Durable weather-resistant construction

Outdoor Installation Considerations

The enclosure's IP65 rating depends on correct installation.

Cable entries, glands, seals and enclosure fixings must be selected and installed appropriately to maintain the specified ingress protection.

Important: IP65 does not mean the isolator is suitable for immersion in water or pressure washing at close range.

IK10 High-Impact Resistance

The BG Electrical CPRSD432AG is specified with an IK10 mechanical impact resistance rating.

IK10 is a recognised impact protection classification indicating resistance to a 20-joule mechanical impact under standardised test conditions.

Benefits of IK10 Protection

• High mechanical impact resistance
• Robust enclosure construction
• Suitable for demanding installation environments
• Practical for outdoor equipment isolation
• Useful for commercial installations
• Helps protect internal switching components

The IK10 rating makes the enclosure particularly relevant to installations where accidental mechanical impacts may occur.

Important: The IK rating relates to mechanical impact resistance and is separate from the IP65 ingress protection rating.

Padlockable Rotary Handle

The BG CPRSD432AG incorporates a black padlockable rotary operating handle.

The handle allows the isolator to be operated between its ON and OFF positions.

A suitable padlock can be used to secure the switch in the OFF position as part of an appropriate electrical isolation procedure.

Benefits of the Padlockable Handle

• Supports safe working isolation
• Helps prevent unauthorised switching
• Practical for maintenance operations
• Suitable for servicing fixed electrical equipment
• Clear rotary operating mechanism
• Convenient external handle
• Suitable for professional electrical installations

Lock-Off Safety

Electrical equipment should be safely isolated before maintenance or servicing.

The padlockable handle supports lock-off procedures when used with suitable equipment and safe working practices.

Important: A padlock is not confirmed as included with the product.

The presence of a padlockable handle does not replace the need to verify that the electrical supply has been safely isolated.

Lid Interlock Safety Feature

The BG Electrical CPRSD432AG incorporates a switch-interlocked enclosure lid.

This feature is designed to prevent the enclosure cover from being opened while the rotary switch is in the ON position.

Benefits of the Lid Interlock

• Helps prevent access while switched ON
• Supports safe maintenance procedures
• Provides an additional safety feature
• Suitable for professional electrical installations
• Practical for outdoor equipment isolation

The lid interlock helps encourage correct switching procedures before the enclosure is opened.

Important: The lid interlock is not a substitute for safe isolation, lock-off and verification that the circuit is dead.

Contemporary Anthracite Grey Finish

The BG CPRSD432AG features a contemporary anthracite grey enclosure.

This provides a modern alternative to conventional grey or white rotary isolators.

The finish has been developed to complement modern building exteriors and contemporary outdoor electrical equipment.

Benefits of the Anthracite Grey Finish

• Modern exterior appearance
• Suitable for contemporary buildings
• Coordinates with dark exterior fittings
• Complements Sync Energy EV chargers
• Contrasting black rotary handle
• Practical for visible outdoor installations
• Suitable for residential and commercial properties

The anthracite grey finish is particularly useful where the isolator will be installed in a visible location.

Designed to Complement Sync Energy EV Chargers

The BG Electrical Anthracite Grey Rotary Isolator has been designed with a colour scheme that complements the Sync Energy EV Charger range.

This makes it a practical choice for EV charging installations where a coordinated exterior appearance is desirable.

Benefits for EV Charging Installations
