Product details

The Siemens 3RV1021-0BA10-ZW97 is a SIRIUS motor protection circuit breaker sized for a 0.06 kW motor at 400 V, with a continuous current rating of 0.2 A and a CLASS 10 trip characteristic.

Screw-type terminals on the main circuit accept 2x (1 to 2.5 mm²) solid or stranded, or 2x (2.5 to 6 mm²) — the larger cross-section is useful for looping through the supply without a separate terminal block.

Compared to the 3RV1011-0GA10, which is a smaller-frame SIRIUS breaker with a lower breaking capacity and no phase-failure detection, the 3RV1021-0BA10-ZW97 adds phase-failure detection and carries the full 100 kA rating across the voltage range.

The breaker is rated for 100,000 mechanical operations of the main contacts. Shock resistance is 25 g for 11 ms.

Frequently asked questions

What is the closest functional second-source to 3RV1021-0BA10-ZW97?

The 3RV1011-0GA10 is a smaller-frame SIRIUS breaker without phase-failure detection and with a lower breaking capacity. The 3RV1021-0BA10-ZW97 adds phase-failure detection and full 100 kA rating, but shares the same 45 mm width and DIN rail clip, so it can drop into the same panel layout if the current rating matches.

Where can I buy 3RV1021-0BA10-ZW97?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the depth of 3RV1021-0BA10-ZW97?

The depth is 96 mm, which fits a 120 mm deep enclosure with wiring clearance behind the rail.

What wire sizes does 3RV1021-0BA10-ZW97 accept?

The screw terminals accept 2x (1 to 2.5 mm²) solid or stranded, and 2x (2.5 to 6 mm²) — the larger range is for looping the supply through without an extra terminal block.
