Design Of The ProductFor motor protection

Product details

The Siemens SIRIUS 3RV1011-0CA15 is a circuit breaker rated for motor protection with Trip Class 10, meaning it trips within 10 seconds at 7.2× the thermal setting — the standard for standard-duty induction motor starts. The 45 mm width fits standard comb-busbar spacing, and the M3 main-contact terminals accept 2× (0.5 to 1.5 mm²) solid or stranded, or 2× (0.75 to 2.5 mm²) — no special ferrules needed for panel wiring.

Deployment context

The 20 mm clearance required upwards and downwards, and 9 mm at the side, means it fits standard DIN-rail enclosures without forced derating — but verify side clearance if packing multiple units on a single rail.

Rated voltage range is 20 to 690 V, covering 24 V control circuits through 400/480/690 V power systems. The auxiliary contact ratings vary by voltage: 1 A at 24 V, 2 A at 110/120/125 V, 0.5 A at 230 V, and no rating required at 240/400/500/690 V — meaning the auxiliary is not intended for switching those higher voltages. Maximum switching frequency is 15 operations per hour in AC-3 and AC-3e duty, which governs motor start frequency.

Frequently asked questions

Where can I buy 3RV1011-0CA15?

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

What is the breaking capacity of 3RV1011-0CA15?

100 kA at 400 V, 500 V, and 690 V — rated for high-fault industrial panels without cascading upstream breakers.

What is the trip class of 3RV1011-0CA15?

Trip Class 10, meaning it trips within 10 seconds at 7.2× the thermal setting — standard for standard-duty induction motor starts.

Will 3RV1011-0CA15 drop into a panel specified around 3RV1011-0GA10 without rewiring?

Both are SIRIUS circuit breakers in the same 45 mm wide footprint with screw and snap-on DIN rail mounting, so the mechanical fit and busbar spacing are identical. However, verify the thermal setting range and auxiliary contact configuration against the 0GA10 variant — the 0CA15 may have a different trip current rating.
