10 Way Consumer Unit for Modern Electrical Installations

The Lewden PRO-R10B-R1S provides 10 usable ways, making it a practical choice for electrical installations requiring multiple outgoing circuits.

A consumer unit is a central component of an electrical installation, distributing the incoming electrical supply to individual circuits through suitable protective devices.

The 10-way configuration allows electricians to plan circuit arrangements according to the requirements of the property.

Typical Circuit Applications

Depending on the installation design, circuits may include:

• Lighting circuits
• Socket outlet circuits
• Kitchen electrical circuits
• Cooker circuits
• Shower circuits
• Heating circuits
• Garage circuits
• Utility room circuits
• Dedicated appliance circuits
• Other suitable final circuits

The number and arrangement of circuits must be determined by a qualified electrical designer or installer.

Important: The consumer unit provides 10 usable ways and 13 modules. The number of protective devices that can be installed depends on their individual module widths and the manufacturer's permitted configuration.

100A Main Switch for Electrical Isolation

The Lewden PRO-R10B-R1S Consumer Unit incorporates a 100A rated main switch.

The main switch provides a means of isolating the electrical installation from the incoming supply.

This is an important feature for maintenance, inspection, testing and electrical installation work.

Benefits of a Main Switch Consumer Unit

• Provides a central point of electrical isolation
• Suitable for single-phase electrical installations
• Supports safe maintenance procedures when correctly used
• Allows the distribution board to be isolated
• Provides a practical arrangement for electrical distribution
• Suitable for installations requiring a 100A-rated main switch

The 100A rating refers to the main switch's rated current and must not be interpreted as confirmation that every installation can safely operate at 100A.

The incoming supply, service equipment, cable sizes, protective devices and installation design must all be assessed before installation.

---

Type 2 Surge Protection Device (SPD)

One of the key features of the Lewden PRO-R10B-R1S is its Type 2 Surge Protection Device.

Surge protection devices are designed to help protect electrical installations and connected equipment against transient overvoltages.

These voltage surges may occur as a result of electrical switching operations or lightning-related electrical disturbances.

A Type 2 SPD is commonly used within distribution boards to provide surge protection as part of a properly designed electrical installation.

Benefits of Type 2 Surge Protection

• Helps protect against transient overvoltages
• Provides additional protection for connected electrical equipment
• Suitable for modern electrical installations
• Supports surge protection requirements where specified
• Conveniently incorporated into the consumer unit
• Useful for properties containing sensitive electronic equipment

Examples of Equipment That May Benefit from Surge Protection

• Televisions
• Computers
• Home networking equipment
• Smart home devices
• Domestic appliances
• Electronic heating controls
• Security systems
• Other sensitive electronic equipment

Important: A Type 2 SPD does not guarantee complete protection against every surge or direct lightning strike. Its effectiveness depends on the electrical installation, earthing arrangement, coordination with other protective devices and correct installation.
