Product details

Rated continuous current is 6.3 A, and the breaking capacity reaches 100 kA at 400 V AC (also 100 kA at 240 V and 500 V AC).

Where it goes and what it connects to

Panel depth allowance must accommodate the 96 mm body depth plus wiring bend radius. Main circuit terminals are screw-type, accepting solid or stranded conductors: 2×(1…2.5 mm²) and 2×(2.5…6 mm²), or AWG 14…10. Front face carries IP20 touch-safe protection; the busbar and live terminals behind the cover are not finger-safe until the cover is installed. No auxiliary contacts are included (0 auxiliary contacts), so any remote status signaling requires a separate auxiliary switch block snapped onto the side.

Environment and durability

The 25g / 11 ms shock resistance covers most industrial vibration and occasional mechanical impact during transport or panel door slam. Mechanical endurance of the main contacts is typically 100 000 operations; the maximum switching rate at AC-3 duty is 15 operations per hour. For a motor starting once every few minutes on a conveyor or pump, that rate is not a constraint — it only matters for high-cycle applications like rapid reversing or jogging.

Frequently asked questions

Where can I buy 3RV1021-1GA10-0FJ0-ZX95 and how do I get a price?

The part is sourced to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing — stock and price are confirmed at quote time.

Will 3RV1021-1GA10-0FJ0-ZX95 drop into a panel specified around 3RV1011-0GA10 without rewiring?

The 3RV1021-1GA10-0FJ0-ZX95 shares the same 45 mm width and 35 mm DIN-rail mounting as the 3RV1011-0GA10, so the physical footprint and rail position are identical. However, verify the terminal arrangement and power dissipation — the 3RV1021 carries a 6.3 A continuous rating versus the 3RV1011-0GA10's rating, so the load current must be within the lower of the two.

What is the listed depth of 3RV1021-1GA10-0FJ0-ZX95?

Depth is 96 mm, width 45 mm, height 97 mm. No additional clearance is required at the sides or rear.

What compliance documentation does Siemens provide for 3RV1021-1GA10-0FJ0-ZX95?

As a standard Siemens SIRIUS motor circuit breaker, it carries CE marking under the Low Voltage Directive and is designed to meet IEC 60947-2 and IEC 60947-4-1. RoHS and REACH declarations are available from Siemens Industry Support. UL and CSA filings apply to the base 3RV1021 family; verify the specific suffix code for UL/CSA listing on this variant.
