High-Capacity 19 Way Consumer Unit

The Lewden PRO-R19B-R1S provides 19 usable ways, making it an excellent choice for electrical installations requiring a larger number of outgoing circuits.

A consumer unit distributes the incoming electrical supply to individual circuits through appropriately selected protective devices.

The 19-way configuration provides flexibility when designing electrical installations with multiple lighting, socket and dedicated appliance circuits.

This makes the PRO-R19B-R1S particularly useful for larger homes, properties with additional electrical equipment and installations requiring a more extensive circuit arrangement.

Typical Circuit Applications

Depending on the electrical installation design, outgoing circuits may include:

• Ground floor lighting
• First floor lighting
• Kitchen lighting
• Socket outlet circuits
• Kitchen socket circuits
• Cooker circuits
• Electric shower circuits
• Heating circuits
• Utility room circuits
• Garage circuits
• Outdoor lighting circuits
• Dedicated appliance circuits
• Home office circuits
• Other suitable final circuits

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

Benefits of a 19 Way Consumer Unit

• Greater capacity for multiple outgoing circuits
• Suitable for larger residential properties
• Practical for installations with numerous electrical loads
• Supports organised circuit distribution
• Useful for extensive electrical refurbishment projects
• Suitable for modern electrical installations
• Provides flexibility when planning circuit arrangements

Important: The consumer unit has 19 usable ways and 22 modules. The number of protective devices that can be installed depends on their module widths and the manufacturer's approved configuration.

100A Main Switch for Electrical Isolation

The Lewden PRO-R19B-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 appropriately designed single-phase 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 main switch is designed to provide isolation rather than individual circuit overcurrent protection.

Individual outgoing circuits require appropriate protective devices selected according to the installation design.

Important: The 100A rating refers to the rated current of the main switch. It does not independently confirm the capacity of the incoming supply or the permissible loading of the installation.

---

Type 2 Surge Protection Device (SPD)

One of the key features of the Lewden PRO-R19B-R1S is its Type 2 Surge Protection Device.

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

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

A Type 2 SPD is commonly installed within electrical distribution boards as part of a properly designed surge protection arrangement.

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
