Malthe Winje GWD4052 Residual Current Circuit Breaker (RCCB) — Type A, 2-Pole, 63 A, 30 mA, 2 Modules

A two-pole residual current circuit breaker rated 63 A with a 30 mA residual current setting, two modules wide. An RCCB disconnects the circuit when the current flowing out does not match the current returning — the signature of a fault to earth, whether through failed insulation or through a person. It provides no overcurrent protection of its own and is installed together with the circuit's MCB or fuse. It is a type A device: it responds to sinusoidal AC residual currents and to pulsating DC residual currents, which is the general-purpose requirement wherever ordinary electronic loads are present. At 30 mA it is rated for the protection of people against electric shock. Rated voltage 230 V, rated insulation voltage 500 V, short-circuit withstand 10 kA, IP20, terminals taking 10-35 mm² conductors, operating range -25 to 60 °C. Supplied by cBallast on quote-to-invoice terms; lead time and freight are quoted per RFQ against the destination Incoterm.
