Design Of The Productfor motor protection

Product details

It carries a 0.32 A continuous current rating and trips CLASS 10, meaning it clears an overload before the motor windings reach their thermal limit under locked-rotor conditions.

Breaking capacity and voltage ceiling

Rated breaking capacity holds at 100 kA across the board — 240 V, 400 V, 500 V, and 690 V AC — so it handles high-fault utility feeds without cascading upstream.

Terminal wiring accepts solid or stranded conductors: 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²) per pole, screw-type. That covers most motor feed cables up to 6 mm². Auxiliary switch can be added on the side; the breaker is prepared for it.

Shock rated at 25g for 11 ms. Front protection is IP20 — finger-safe but not washdown-rated. RoHS compliance date is 01.05.2012, and the lifecycle status is current, so this is an active catalog line, not a phase-out.

Frequently asked questions

Where can I buy 3RV1021-0DA10-ZW97 and get a price?

It is sourced through independent distribution and quoted to order against an RFQ. Submit a request for quote; availability and current pricing are confirmed at that time.

What is the closest functional second-source to 3RV1021-0DA10-ZW97?

The 3RV1011-0GA10 is a smaller-frame SIRIUS motor protection breaker in the same family, but it has a lower breaking capacity and different terminal layout. The 3RV1021-0DA10-ZW97 is the 0.32 A variant in the 3RV1021 frame; the 3RV1011-0GA10 is a physically narrower unit from the 3RV1011 series. They are not drop-in replacements — the 3RV1021 frame is 45 mm wide versus the 3RV1011's 45 mm as well, but the terminal spacing and auxiliary switch compatibility differ. Check the specific ratings before substituting.

What is the depth of 3RV1021-0DA10-ZW97?

The depth is 96 mm, with a width of 45 mm and height of 97 mm.

What wire sizes does the 3RV1021-0DA10-ZW97 accept?

Screw terminals accept solid or stranded conductors: 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²) per pole, plus AWG 14 to 10 for the main contacts.

Will 3RV1021-0DA10-ZW97 drop into a panel specified around 3RV1011-0GA10?

Both mount on 35 mm DIN rail and share the same 45 mm width, so the rail footprint matches. However, the 3RV1021 frame is 96 mm deep versus the 3RV1011's shallower depth, and the terminal layout may differ. Verify gland plate clearance and wiring access before swapping.

What compliance documentation does Siemens provide for this breaker?

RoHS compliance is dated 01.05.2012. The SIRIUS series typically carries UL, CSA, CE, and IEC certifications; specific documentation is available from Siemens on request.
