Product details

The Trip Class 10 rating means it will trip within 10 seconds at 7.2× the thermal setting, matching the startup profile of standard induction motors.

The 45 mm width and 97 mm depth fit standard panel layouts — no extra side clearance needed forward or backward (0 mm each way), though 50 mm above and below is required for ventilation and wiring access. Spring-loaded terminals on the main circuit accept 2× (0.5 to 4 mm²) solid or stranded wire, so no lug crimping for typical motor branch circuits.

Frequently asked questions

What is the breaking capacity of 3RV2011-0BA20 at 400 V?

100 kA at 400 V AC, both for the rated value and for the AC circuit — that covers most industrial distribution panels without needing upstream current-limiting fuses.

Does 3RV2011-0BA20 detect phase failure?

Yes, phase failure detection is built in — it will trip if one phase drops out, preventing single-phasing damage to the motor.

What is the Trip Class of this circuit breaker?

Trip Class 10, meaning it trips within 10 seconds at 7.2× the thermal setting — standard for general-purpose motor starting.

Where can I buy 3RV2011-0BA20?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.
