Description

The BG CUSW100-02 100A double pole main switch isolator provides safe and dependable isolation of the incoming electrical supply within a compatible BG consumer unit. Its double-pole, 1P+N configuration disconnects both the live and neutral conductors, creating a clear isolation point for electrical installation, inspection, maintenance and emergency switching.

Designed for modern UK electrical installations, this bidirectional 100A main switch can accommodate power flow in either direction. This makes it suitable for compatible installations involving conventional incoming supplies and modern renewable-energy systems where bidirectional electrical devices may be required.

Specification

The BG CUSW100-02 is a 100A bidirectional double-pole main switch isolator designed for compatible BG consumer units. It safely disconnects the live and neutral conductors from the incoming supply, providing a clear isolation point during installation, electrical maintenance or an emergency.

The device occupies two DIN-rail modules, accepts cable sizes up to 35mm² and has the neutral pole positioned on the right. It is rated for 230V AC operation, complies with IEC/EN 60947-3 and is designed for BS 7671 Amendment 4 installations.

FAQ's

What is the BG CUSW100-02 used for?

It is used as the main isolation switch inside a compatible consumer unit. Switching it off disconnects both the live and neutral conductors from the incoming electrical supply.

Is the CUSW100-02 bidirectional?

Yes. BG’s current technical specification identifies the CUSW100-02 as bidirectional, meaning it is designed to accommodate electrical power flow in either direction.

Is it a double-pole isolator?

Yes. It has a 1P+N double-pole configuration that switches the live and neutral conductors together.

Does this main switch provide circuit protection?

The CUSW100-02 is an isolation device rather than an MCB, RCD or RCBO. Separate protective devices are required to provide overload, short-circuit or residual-current protection within the installation.

How much consumer-unit space does it require?

It occupies two DIN-rail modules and has a product width of approximately 35.6mm.

What cable size does it accept?

The maximum cable capacity listed in BG’s technical specification is 35mm².

Can it be retrofitted?

BG identifies the device as retrofittable for compatible BG surface-mounted consumer units. Product compatibility should be confirmed before installation.

What standard does it comply with?

The current BG specification lists compliance with IEC/EN 60947-3, the standard covering switches, disconnectors and switch-disconnectors.

What warranty is included?

BG’s circuit-protection range is backed by a ten-year warranty, subject to the manufacturer’s warranty conditions.
