NHXB / NSB MCB ( Type B )
Rated 50 Amps
General Domestic Consumer Unit use
The Miniature Circuit Breaker for the Wylex NH Range of consumer Units, 6ka rated for domestic duty, in type B for surges between 3-5 times the start up current.
Wylex NSB MCB's detect overcurrents due to both overload and fault currents.
The MCB will operate and interrupt the supply to prevent damage to the installation.
Wylex NSB Domestic MCBs have a short circuit breaking capacity of 6000A (M6).
The operating dolly may be locked in either the ON or OFF position without affecting the ability of the trip mechanism to operate.
When in the off position, a contact gap of 4 mm is achieved. Wylex NSB MCBs may therefore be used as single pole isolating switches where appropriate.
