Product details

What this 0.8 A SIRIUS breaker does in a motor branch

The Siemens 3RV1021-0HA10-0FJ0-ZX95 is a SIRIUS motor protection circuit breaker rated 0.8 A continuous current, designed to protect a 0.18 kW motor at 400 V.

Breaking capacity and fault clearing

This breaker carries a 100 kA breaking capacity all the way from 240 V through 690 V AC. That is the full rated interrupting rating across the voltage range — no derating curve to watch at higher voltages. For a panel with a transformer-fed 400 V supply and a high available fault current, this unit clears a bolted fault without upstream fuses needing to open.

Mounts in any position — vertical, horizontal, upside down — on 35 mm DIN rail. Zero clearance needed at the back or sides, so it packs tight against adjacent devices in a crowded enclosure. Front face carries an IP20 finger-safe shroud.

Frequently asked questions

Where can I buy 3RV1021-0HA10-0FJ0-ZX95 and get a price?

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

What is the closest functional second-source for 3RV1021-0HA10-0FJ0-ZX95?

The 3RV1011-0GA10 is a similar SIRIUS motor protection breaker but with a different current rating and trip curve. Verify the continuous current and CLASS rating against your motor FLA before substituting — the 3RV1021-0HA10-0FJ0-ZX95 is a 0.8 A CLASS 10 device, so the replacement must match both the thermal overload setting and the short-circuit breaking capacity for the branch.

What is the depth of 3RV1021-0HA10-0FJ0-ZX95?

The depth is 96 mm, which clears a standard 100 mm deep enclosure door.

What wire sizes does the 3RV1021-0HA10-0FJ0-ZX95 accept?

The screw terminals accept 2x (1 to 2.5 mm²) or 2x (2.5 to 6 mm²) solid or stranded conductors, and 2x (14 to 10 AWG) for the main contacts.

Will 3RV1021-0HA10-0FJ0-ZX95 drop into a panel specified for 3RV1011-0GA10?

Both are SIRIUS 3RV1 series breakers with the same 45 mm width and DIN rail mounting, so the physical fit and terminal layout are identical. The difference is the electrical rating — verify the continuous current and trip class match your motor protection requirements before swapping.
