Sectionalising Withdrawable Breaker cubicle, type SBW

The SBW panel is a sectionalising circuit breaker panel with a withdrawable circuit breaker. The SBW is used together with the bus riser cubicle (BRC). The cubicle is designed for sectionalising the

busbar in the switchgear. It is available with either vacuum or SF6-gas circuit breaker. The CB truck handles the disconnecting function of the circuit breaker. A separate earthing switch enables earthing of the busbar.


The door is mechanically interlocked with the circuit breaker and the earthing switch to provide personnel safety.


A wide range of secondary control & protection equipment is available for the cubicle, from the simplest self-powered protection relays to complicated protection, monitoring and controlling devices.
