The Siemens 5SV4312-0 is a SENTRON residual current circuit breaker (RCCB), 2-pole, Type AC, rated 25 A with 30 mA sensitivity on a 230 V AC, 50 Hz supply.
The 70 mm installation depth matches the typical SENTRON RCCB/MCB profile — no extra clearance needed behind the DIN rail. Supply can land top or bottom, and the IP20 rating (with conductors connected) is fine for enclosed distribution boards; no special sealing required.
It is a 2-pole Type AC residual current circuit breaker rated 25 A, 30 mA, 230 V AC, 50 Hz. It protects branch circuits against earth faults in residential and light commercial distribution boards, tripping on sinusoidal AC residual currents.
Rated current 25 A, residual sensitivity 30 mA, supply voltage 230 V AC at 50 Hz, short-circuit current rating 10 kA, 2-pole, Type AC (instantaneous).
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The 5SV4312-0 is a 2-pole RCCB (36 mm wide, 70 mm deep) while the 5SL4363-7 is a 3-pole MCB (54 mm wide, 76 mm deep). The 5SV4312-0 is narrower and shallower, so it fits the same DIN-rail footprint but occupies fewer modular width units. No rewiring needed for the RCCB function, but the 5SL4363-7 is a different device class (MCB, not RCCB) — they are not drop-in functional substitutes.
