Low Voltage Switchgear
We test manufacturer’s air circuit breakers(ACB), moulded case circuit breakers(MCCB), fuse switches, disconnectors, automatic transfer switches(ATSE), motor starters and control devices, miniature circuit breakers(MCB), residual current devices(RCB) and residual current operated circuit breakers(RCOB).
Frequently manufacturers want to certify a range of equipment, i.e. a frame size. In this case we have to check each model within the frame size to confirm that we have a homogenous series and that there are no construction breaks. Construction breaks introduces additional testing and expense.
Typical standards include:
