Product details

Motor Protection Circuit Breaker, 12.5 A — SIRIUS 3RV2011-1KA20

The Siemens 3RV2011-1KA20 is a SIRIUS-branded motor protection circuit breaker designed specifically for motor protection, with a continuous current rating of 12.5 A at both 480 V and 600 V. Short-circuit breaking capacity is 100 kA at 400 V and 240 V, 42 kA at 500 V, and 4 kA at 690 V, giving solid SCCR headroom for most industrial panel designs.

Mounting and Termination

Dimensions are 45 mm wide, 106 mm high, 97 mm deep — a standard 45 mm module that fits alongside contactors in a motor starter lineup. Required clearance distances: 50 mm upwards and downwards, 30 mm at the sides, zero forwards and backwards.

Frequently asked questions

What are the key ratings for the 3RV2011-1KA20?

Continuous current is 12.5 A at 480 V and 600 V. Short-circuit breaking capacity is 100 kA at 400 V, 42 kA at 500 V, and 4 kA at 690 V. Trip class is Class 10. Phase failure detection is included.

What is the mounting method and required clearance?

It mounts on 35 mm DIN rail per DIN EN 60715, screw or snap-on, in any orientation. Clearances: 50 mm upwards and downwards, 30 mm at sides, zero forwards and backwards.
