Proteus Switchgear’s introduction of a new portfolio of 4 pole, 3 module RCBOs and MCBs which fit the existing busbar system means that electrical professionals now have access to a unique set of devices that can switch 3 phases and neutral.
The 10kA, Type A RCBO will save considerable space, time and money when installing on-site or when designing custom built boards. Gone are the days of having to accommodate additional enclosures fitted with 4 pole RCDs where these had to be cabled from a 3 pole MCB and the neutral bar in the adjacent MCB board.
Now you can simply install the Proteus 4 pole RCBOs, without having to do all the extra cabling. The RCBO combines overload, short circuit and earth leakage protection all in one compact device. The neutral pole is a switched pole, designed to ‘make first and break last’, ensuring neutral is established before phase poles close.
It can be used in any application that a traditional MCB/RCD combination would be used, but without the additional work of installing two separate devices. This is particularly useful in EV installations where a Type A MCB/RCD combination is required.
