Product details

The Siemens SIRIUS 3RV1011-1CA20-ZW95 is a motor protection circuit breaker rated for 2.5 A continuous current, sized for a 0.75 kW motor at 400 V.

At 400 V AC this breaker interrupts fault currents up to 100 kA, which covers most industrial panel SCCR requirements. At 690 V the breaking capacity drops to 2 kA — still adequate for a motor branch circuit on a 690 V system, but coordination with an upstream fuse or MCCB needs to account for that lower ceiling.

Spring-loaded terminals on both main and auxiliary circuits accept 0.25 to 2.5 mm² solid or stranded wire, or 0.25 to 1.5 mm² finely stranded with ferrule. No screwdriver needed for termination; strip length is 8 mm for a clean connection.

Frequently asked questions

What is the closest functional second-source for 3RV1011-1CA20-ZW95?

The 3RV1011-1HA10 is a peer in the same SIRIUS family. The key difference is the continuous current rating — 3RV1011-1CA20-ZW95 is set for 2.5 A, while the 1HA10 variant covers a different trip range. Verify the motor FLA before substituting; the footprint and terminal style are the same, so it will drop into the same DIN rail slot without rewiring.

Where can I buy 3RV1011-1CA20-ZW95?
