Design Of The ProductFor starter combinations

Product details

The Siemens 3RV2331-4JC10 is a SIRIUS circuit breaker, specifically designed for starter combinations — meaning it integrates motor protection and disconnection in one unit, sized for a 18.5 kW motor at 230 V or 50 hp at 460/480 V.

Breaking capacity — the real-world number

At 400 V the 3RV2331-4JC10 interrupts 30 kA — that is the rating that governs fault clearance in a standard 400 V industrial panel. At 240 V it handles 100 kA, at 500 V it drops to 5 kA, and at 690 V to 2 kA.

The breaker is 55 mm wide, 140 mm tall, and 149 mm deep.
