Product details

Motor protection circuit breaker for 0.4 A loads

Phase failure detection and trip class

Built-in phase failure detection protects the motor against single-phasing — a leading cause of winding burnout in delta-connected loads. The CLASS 10 trip class is the standard for general-purpose squirrel-cage motors; it allows the inrush transient to pass while still clearing a sustained overload before the motor insulation reaches its thermal limit. The 0.09 kW power rating at 400 V confirms the motor size this breaker is designed to protect.

The 45 mm width occupies a single modular unit, leaving room for a contactor and overload relay in the same row. Front face carries IP20 protection — safe for finger-probe access inside an enclosure.

Frequently asked questions

What is the breaking capacity of this circuit breaker?

The 3RV1021-0EA10-0FJ0-ZX95 has a breaking capacity of 100 kA at 400 V AC, 100 kA at 500 V AC, and 100 kA at 690 V AC.

Where can I buy 3RV1021-0EA10-0FJ0-ZX95?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock or lead-time figures are published here.

Will 3RV1021-0EA10-0FJ0-ZX95 drop into a panel specified around 3RV1011-0GA10?

Both are SIRIUS motor protection circuit breakers with the same 45 mm width and DIN-rail mounting, so the footprint is identical. The key difference is the rated current: this unit is 0.4 A, while the 3RV1011-0GA10 carries a different current rating. Verify the motor FLA before substituting — the terminals and trip class are compatible.
