Product details

The Siemens 3RV1011-0CA20-ZX95 is a SIRIUS motor-protection circuit breaker designed for 3-phase AC motors up to 0.06 kW at 400 V. Rated continuous current is 0.25 A, with a CLASS 10 trip characteristic — meaning it will trip within 10 seconds at 7.2× rated current, matching the thermal curve of standard squirrel-cage induction motors during start-up. Ground fault detection is not included — that requires a separate residual-current device or a different SIRIUS variant.

Main circuit terminals are spring-loaded, accepting 2x (0.25 to 2.5 mm²) solid or 2x (0.25 to 1.5 mm²) fine-stranded with ferrule. The auxiliary switch option allows a separate signal contact for remote status.

Shock resistance is 25g for 11 ms, and mechanical endurance of the main contacts is rated at 100,000 operations. Maximum switching frequency at AC-3 duty is 15 operations per hour.

Frequently asked questions

What terminals does this breaker use?

The main current circuit uses spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or 2x (0.25 to 1.5 mm²) fine-stranded with ferrule.

Will the 3RV1011-0CA20-ZX95 drop into a panel specified for the 3RV1011-0GA10?

Both are 45 mm wide SIRIUS motor-protection breakers with the same mounting rail and terminal style, so the mechanical fit is identical. The difference is the current rating and trip class — verify the 0.25 A / CLASS 10 combination matches your motor's full-load current and start profile before substituting.
