Product details

Motor Protection Circuit Breaker, 3.2 A, 100 kA — SIRIUS 3RV1021-1DA10-ZW97

The Siemens 3RV1021-1DA10-ZW97 is a SIRIUS motor protection circuit breaker rated for 3.2 A continuous current, with a 100 kA breaking capacity at 400 V AC — enough to handle high-fault-current industrial panels without cascading upstream.

Main and auxiliary/control circuits use screw-type terminals. Solid and stranded conductors are accepted: 2× (1 … 2.5 mm²) and 2× (2.5 … 6 mm²), with the same range for finely stranded wire with ferrule. AWG equivalents are 2× (14 … 10).

Shock resistance is 25 g for 11 ms. The product carries a substance prohibitance date of 01.05.2012, consistent with RoHS compliance. No ground fault detection is built in — that is handled separately downstream if needed.

Frequently asked questions

What is the closest functional second-source to 3RV1021-1DA10-ZW97?

The 3RV1011-0HA10 and 3RV1011-0GA10 are earlier SIRIUS frame sizes with lower breaking capacities and different current ranges. The 3RV2021-1FA15 is a larger-frame sibling. None are drop-in replacements without rewiring — verify the terminal layout and mounting footprint against your panel design before substituting.

What is the depth of 3RV1021-1DA10-ZW97?

The depth is 96 mm, with a width of 45 mm and height of 97 mm. No backward or side clearance is required for mounting.

What conductor sizes does 3RV1021-1DA10-ZW97 accept?

Solid and stranded conductors: 2× (1 … 2.5 mm²) and 2× (2.5 … 6 mm²). Finely stranded with ferrule uses the same ranges. AWG equivalents: 2× (14 … 10). All connections are screw-type terminals.
