Product details

The Siemens 3RV1021-0GA15 is a SIRIUS motor protection circuit breaker rated for 0.63 A continuous current with a Class 10 trip characteristic. It delivers 100 kA breaking capacity across the 240 V to 690 V AC range, so it handles high-fault-current installations without cascading to upstream devices. Phase failure detection is built in — the breaker trips on a lost phase before the motor single-phases to failure.

Mounting and integration

Snap-on mounting onto 35 mm DIN rail per EN 50022, with screw-type terminals for the main circuit and auxiliary/control circuit. The 45 mm width and 96 mm depth fit standard panel spacing; mounting position is any, so it works in vertical or horizontal busway layouts. Screw terminals accept solid conductors 2x (0.5–1.5 mm²) and 2x (0.75–2.5 mm²), or stranded 2x (1–2.5 mm²) and 2x (2.5–6 mm²).

Frequently asked questions

What is the breaking capacity of 3RV1021-0GA15?

100 kA at 240 V, 400 V, 500 V, and 690 V AC — consistent across the full voltage range, so no derating needed at higher voltages.

Does 3RV1021-0GA15 detect phase failure?

Yes, phase failure detection is included. The breaker will trip if one phase is lost, protecting the motor from single-phasing.

Where can I buy 3RV1021-0GA15 and how is it quoted?

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