Crabtree 32A 30mA SPN C Curve 6kA Type A RCBO
£49.66 Incl. VAT
This Residual Current Circuit Breaker, employs the current balance principle which involves the supply conductors to the load (phase and neutral) being wound onto a common transformer core to form the primary windings. The RCD trip mechanism will operate at a residual current of between 50–100% of its rated residual operating current. Under healthy circuit conditions, the current in the phase conductor is equal to the current in the neutral and the vector sum of the current is zero. In the event of an earth fault, an amount of current will flow to earth, creating an out of balance situation in the transformer assembly. This out of balance is detected by the secondary winding of the transformer and at a pre-determined level of out of balance will activate the trip mechanism. A test button is provided on all RCDs to enable the operation of the device to be checked. · · · Single module, RCBO · · 32A C curve (MCB), 30mA Type A (RCD) · · Single pole · · Plug in
