RCCB is designed in such a way that it continuously senses and compares differences (residual current value) in current values between the live and neutral wires. Any small change in the current value on account of such an event would trigger the RCCB to trip off the circuit.
These devices must be used in series with an MCB or fuse that protects them from the potentially damaging thermal and dynamic stresses of any overcurrents.
They also act as the main disconnecting switches upstream of any derived MCB. It can be easily mounted on a DIN channel (standard size 35 mm) using a bistable DIN clip.
Manufactured from high-impact fire-retardant thermoplastic material for extra strength & insulation.
High short circuit current withstand capacity & dual protection.
Lowest power consumption, thus cost-effective & energy-saving
Shrouded terminals are finger safe
Test Button for regular inspection
SELVO RCCBs are available in DP & FP versions with rated currents of 40A & 63A and rated sensitivities of 30mA & 100mA
