Product details

The Siemens SIRIUS 3RV1021-1EA10-ZW96 is a 3-pole motor protection circuit breaker rated for 4 A continuous current with a Class 10 trip characteristic, sized for a 1.5 kW motor at 400 V AC. It provides phase failure detection and has a breaking capacity of 100 kA at 400 V AC, dropping to 6 kA at 690 V AC — meaning it can handle heavy fault currents on a standard 400 V distribution system without needing an upstream fuse for most installations.

Front IP20 protection keeps live terminals out of accidental contact during panel work. Screw terminals on both main and auxiliary circuits accept 1–2.5 mm² solid or stranded (2x) and 2.5–6 mm² (2x), with AWG 14–10 equivalents for the main contacts. Zero clearance needed at the back or sides for ventilation.

RoHS compliance date marked as 01.05.2012. Shock rated at 25g for 11 ms.

Frequently asked questions

What is the breaking capacity of this breaker at 400 V?

100 kA at 400 V AC, which covers most industrial distribution faults without requiring upstream fusing.

What is the closest functional alternative to 3RV1021-1EA10-ZW96?

The 3RV2021-1FA15 is a higher-rated sibling in the same SIRIUS family — same DIN footprint, same Class 10 trip, but a different current rating. It will not drop in without rewiring; the terminal layout and trip curve are matched to its own rating.

Where can I buy 3RV1021-1EA10-ZW96?

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