MCB accessories and auxiliaries from ABB add remote tripping and status signaling to DIN-rail miniature circuit breakers. The range covers S2C auxiliary contacts, shunt trips and S800 shunt operation releases, with about 20 products. Stoklink ships worldwide from Turkey and quotes on request.
What's in this range
- S2C-H6R auxiliary contacts, 1CO, and 1NO/1NC blocks.
- S2C-A1 shunt trips for 12 to 110 V.
- S800 shunt operation releases such as 24 V AC/DC types.
- Parent range: Miniature Circuit Breakers (MCB).
How to choose
- Match the accessory to the breaker family, as S2C and S800 parts are not interchangeable.
- Check the coil voltage and whether it is AC, DC or both.
- Select contact configuration (NO, NC, CO) to the signaling need.
FAQ
What does a shunt trip do?
It opens the breaker remotely when its coil is energized, for example from an emergency stop circuit.
Is an auxiliary contact the same as a signal contact?
An auxiliary contact follows the breaker position. A signal contact indicates a trip. Check the datasheet for the function.
Do you ship accessories with the breakers?
Stoklink ships worldwide from Turkey on EXW terms. Lead time depends on distributor stock, so request a quote with your part numbers and quantities.
