- 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 which 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 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 concumption thus cost effective & energy saving
- Shrouded terminals are finger safe
- Test Button for regular inspection
- SELVO RCCB's are available in DP & FP versions with rated current as 40A & 63A and rated sensitivity as 30mA & 100mA
