Product details

The Siemens 3RV1011-1CA20-ZW97 is a SIRIUS motor protection circuit breaker rated for 2.5 A continuous current, with a CLASS 10 trip characteristic, sized for a 0.75 kW motor at 400 V three-phase. The IP20 front means it's finger-safe for panel builders working live.

Trip class and motor protection

It includes phase failure detection, so if you lose a phase on a lightly loaded motor, the breaker trips rather than letting the motor single-phase and burn. Rated operating frequency is 15 operations per hour maximum at AC-3 duty, which covers most conveyor and pump starts but not frequent jogging or reversing cycles.

Backwards clearance is 0 mm, so it can sit flush against the back panel. Spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or 2x (0.25 to 1.5 mm²) finely stranded with ferrules. AWG equivalent is 2x (24 to 14). No screw torque to worry about — strip and push.

Shock rated at 25g for 11 ms.

Frequently asked questions

Where can I buy 3RV1011-1CA20-ZW97 and get a price?

It is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is the trip class and what does it mean?

CLASS 10 means the breaker trips within 10 seconds at 7.2× the current setting, matching standard DOL motor starts.

What is the breaking capacity at 400 V?

100 kA at 400 V AC, which is high enough for most industrial panels without needing upstream current-limiting fuses.

Does it include phase failure protection?

Yes, phase failure detection is built in — it will trip if a phase is lost on a lightly loaded motor.

What wire sizes does the spring terminal accept?

Solid: 2x (0.25 to 2.5 mm²); finely stranded with ferrule: 2x (0.25 to 1.5 mm²); AWG: 2x (24 to 14).
