Product details

The Siemens SIRIUS 3RV1011-1DA20-ZW98 is a 3-pole motor protection circuit breaker rated for 3.2 A continuous current with a Class 10 trip characteristic. The spring-loaded terminals accept 2x (0.25... 2.5 mm²) solid or stranded conductors, which covers the typical control and power wiring for a 1.1 kW motor at 400 V.

Zero clearance at the back and sides means no extra spacing between units on the rail. Any mounting position is permitted, so horizontal or vertical rail orientation is fine.

Electrical ratings and trip behavior

Rated operating voltage is 690 V AC, with breaking capacity derating to 3 kA at 500 V and 2 kA at 690 V. The surge voltage withstand is 6 kV, adequate for solidly grounded 400 V systems.

Frequently asked questions

What is the breaking capacity of 3RV1011-1DA20-ZW98 at 400 V?

100 kA at 400 V AC, which allows it to interrupt high fault currents without upstream fuses in most panel designs.

What conductor sizes does the spring-loaded terminal accept?

Solid conductors: 2x (0.25... 2.5 mm²). Finely stranded with core end processing: 2x (0.25... 1.5 mm²). Finely stranded without core end processing: 2x (0.25... 2.5 mm²). AWG equivalents: 2x (24... 14).

Where can I buy 3RV1011-1DA20-ZW98 and how is it quoted?

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