The Siemens SIRIUS 3RV1952-1ED0 is a shunt release designed specifically for the size 3RV13 5 circuit breaker frame. It operates on a dual-rated control voltage of 110-127 V AC or 110-125 V DC, giving you flexibility across common control supply rails in European and North American panels.
The coil operates at 110-127 V AC or 110-125 V DC. It is pulsed to trigger the trip mechanism, not continuous-duty. The form factor is keyed to the 3RV13 5 frame only. It snaps into the accessory slot on the left side of the breaker, sharing the same DIN-rail footprint. No rewiring of the main power circuit is required — the shunt release connects to the control terminals on the breaker face.
