Product details

The Siemens 3RV1011-0KA25 is a SIRIUS motor protection circuit breaker designed for motor protection, sized for a 1.25 A continuous current rating and a 0.37 kW motor at 400 V AC.

Breaking capacity and fault clearing

Rated breaking capacity hits 100 kA at 240 V, 400 V, and 500 V AC, dropping to 2 kA at 690 V AC.

Width is 45 mm, depth 81 mm, height 90 mm — fits a standard 45 mm-wide DIN slot. Spring-loaded terminals on both main and auxiliary/control circuits accept 2x (0.25... 2.5 mm²) solid or 2x (24... 14) AWG. Zero clearance needed at the side or backwards, so you can pack units tight on the rail.

Environmental and protection ratings

IP20 on the front — finger-safe but not washdown-rated. Shock resistance 25g / 11 ms. Mounting position any, which simplifies panel layout.

The auxiliary switch is transverse and field-addable. For RoHS compliance, the substance prohibition date is 01.01.2013 (RoHS 2 effective).
