Product details

Motor protection circuit breaker, 2.5 A, CLASS 10 — SIRIUS 3RV1011-1CA20-ZW96

The Siemens 3RV1011-1CA20-ZW96 is a SIRIUS motor protection circuit breaker rated for 2.5 A continuous current, sized for a 0.75 kW motor at 400 V AC. Three poles for the main current circuit, with spring-loaded terminals accepting 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule. Breaking capacity is 100 kA at 240 V and 400 V AC, derating to 10 kA at 500 V and 2 kA at 690 V.

Width is 45 mm, depth 81 mm, height 90 mm. The 0 mm clearance required at the back and sides means it can be packed tight against adjacent devices — no derating for side-by-side mounting in a standard enclosure. Front face carries IP20 protection — safe for finger contact in a closed panel. Shock rated at 25g for 11 ms, any mounting position accepted.

Frequently asked questions

How do I get current pricing and availability for 3RV1011-1CA20-ZW96?

Submit an RFQ through this listing. The part is sourced to order through independent distribution; a confirmed price and lead time are provided at quote time.

What is 3RV1011-1CA20-ZW96's listed depth?

The depth is 81 mm, with 0 mm clearance required at the back and sides for side-by-side DIN rail mounting.

What wire sizes does the spring terminal accept?

The spring-loaded terminals accept 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with core end processing. AWG equivalent is 2x (24... 14) for the main contacts.

Will 3RV1011-1CA20-ZW96 drop into a panel specified around 3RV1011-1HA10?

Both are 45 mm wide SIRIUS 3RV10 breakers on the same DIN rail footprint, so the mechanical fit is identical. The difference is in the trip rating and accessories — verify the continuous current and auxiliary switch count match your BOM before swapping.

What compliance documentation does Siemens provide for 3RV1011-1CA20-ZW96?

Standard Siemens SIRIUS documentation includes a CE declaration of conformity and the product is designed to meet IEC/EN 60947-2 and 60947-4-1. RoHS and REACH compliance declarations are available from Siemens support. UL and CSA listings are typical for this series but should be confirmed per the specific variant.
