Product details

It's rated for a continuous current of 6.3 A and switches motor loads up to 2.2 kW at 400 V AC (AC-3 duty).

Breaking capacity — what it handles in a fault

This breaker carries a breaking capacity of 100 kA at 240 V, 400 V, and 500 V AC, dropping to 6 kA at 690 V AC. At 690 V, the 6 kA rating still covers most motor branch circuits in industrial environments.

The 45 mm width (3 module spaces) fits standard enclosure rail. Screw-type terminals on the main circuit accept solid or stranded conductors: 2× (1 … 2.5 mm²) or 2× (2.5 … 6 mm²), with AWG equivalents of 2× (14 … 10). No special tools beyond a screwdriver needed for termination. Zero clearance required at the sides or rear — 0 mm backwards and at the side — so you can pack modules tight on the rail.

IP20 protection on the front (finger-safe terminals), suitable for installation inside a locked or tool-accessible enclosure. Shock resistance of 25g for 11 ms — survives typical industrial vibration and occasional impacts. Mountable in any position, which simplifies panel layout.

Protection and diagnostics features

Includes phase failure detection — if one phase drops out, the breaker trips to prevent single-phasing motor damage. No ground fault detection built in (you'd need a separate GFPE module for that). An auxiliary switch is available (order separately) for remote status indication. The breaker has a typical mechanical life of 100,000 operations on the main contacts, and at AC-3 duty it's rated for 15 switching operations per hour maximum — adequate for most motor start applications, but not for frequent jogging or reversing cycles.

Frequently asked questions

Where can I buy 3RV1021-1GA10-ZW97 and how do I get a price?

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 3RV1021-1GA10-ZW97's listed depth?

The listed depth is 96 mm. Combined with a width of 45 mm and height of 97 mm, it occupies three DIN module spaces on a 35 mm rail.

Will 3RV1021-1GA10-ZW97 drop into a panel that was specified around 3RV6011-0CA10 without rewiring?

The 3RV1021-1GA10-ZW97 uses screw-type terminals accepting 2× (1 … 2.5 mm²) and 2× (2.5 … 6 mm²) solid or stranded conductors. If the 3RV6011-0CA10 panel was wired with conductors in that range, the terminals are compatible. However, verify the mounting footprint — both snap onto 35 mm DIN rail, but dimensional differences (width, depth) may affect rail spacing and adjacent device clearance. Always compare the physical dimensions before assuming a drop-in replacement.

What compliance documentation is available for 3RV1021-1GA10-ZW97?

As a Siemens SIRIUS product, this breaker carries CE marking for the European market and is designed to meet IEC/EN 60947-2 and 60947-4-1 standards for circuit breakers and motor starters. UL and CSA listings are typical for the SIRIUS family but should be verified against the specific variant's nameplate markings. RoHS and REACH declarations are available from Siemens upon request.
