Residual current circuit breakers (RCCB) from ABB, Siemens and Schneider Electric protect people and installations against earth leakage on DIN-rail panels. The range includes F200, FH200, 5SV3, 5SV5, Acti 9 iID and Easy9 Pro in 2-pole, 4-pole and 1+N versions, with sensitivities from 30 mA to 300 mA. Stoklink ships worldwide from Turkey and quotes project volumes.
What's in this range
- ABB F200 and FH200 series in Type AC, A and B, including high-current versions up to 125 A.
- Siemens SENTRON 5SV3 and 5SV5 devices in 2P and 4P, 230 V and 400 V.
- Schneider Electric Acti 9 iID and Easy9 RCCBs.
- Type B devices for drive circuits.
How to choose
- Rated current: at least the total load current of the downstream circuits.
- Sensitivity: 30 mA for personal protection, 300 mA for fire protection or as a selective upstream device.
- Type: AC for resistive loads, A for electronics, B for drives and inverters.
- Short-circuit protection: an RCCB has none. Pair it with an upstream MCB or fuse.
- Poles: 2P for single-phase, 4P for three-phase with neutral.
FAQ
Can an RCCB replace an MCB?
No. An RCCB does not trip on overload or short circuit. It must be protected by an upstream MCB or fuse.
What does Type A mean on an RCCB?
Type A detects sinusoidal AC and pulsating DC residual currents. Type AC detects sinusoidal AC only.
Can I order RCCBs for a project in bulk?
Yes. Request a quote with the part numbers and quantities. Stoklink ships from Turkey, EXW.
