Product details

The Siemens 3RV2011-1KA20-ZW97 is a SIRIUS motor-protection circuit breaker designed for motor branch circuits. The continuous current rating at 480 V is 12.5 A, matching a 7.5 kW (10 hp) motor at 460/480 V.

Width is 45 mm, depth 97 mm, height 106 mm. It mounts in any position. Clearance requirements: 50 mm above and below, 30 mm to the sides, zero forwards and backwards — so it can sit flush against a back panel or a neighboring device. Wire range is 2 × 0.5 to 4 mm² solid or stranded, which covers most motor control wiring up to 4 mm². The spring terminals accept ferruled conductors cleanly.

For a BOM line that needs a motor-protection CB with spring terminals and CLASS 10 trip, this is a direct fit.

Frequently asked questions

What is the breaking capacity of 3RV2011-1KA20-ZW97 at 400 V?

100 kA at 400 V. It also carries 42 kA at 500 V and 4 kA at 690 V.

Does 3RV2011-1KA20-ZW97 have phase failure detection?

Yes, phase failure detection is built in. Ground fault detection is not included.

What wire size does the spring terminal accept?

2 × 0.5 to 4 mm² solid or stranded. Ferruled conductors work well.

Where can I buy 3RV2011-1KA20-ZW97?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
