Product details

Motor protection circuit breaker for Class 10 coordination

Rated interrupting capacity reaches 100 kA at both 240 V and 400 V AC, so it can be applied on high-fault-capacity distribution panels without requiring upstream current-limiting fuses.

For a panel originally specified around the 3RV2021-1GA15, the 3RV2021-1HA10-ZX95 shares the same 45 mm footprint and DIN-rail mounting, so it drops in without rewiring or enclosure modifications. The functional difference is in the trip setting range and interrupting ratings — verify those against your motor FLA before substituting.

Integration note

Screw-type terminals on the main circuit accept 2x (1–2.5 mm²) solid/stranded or 2x (2.5–10 mm²). The M4 contact screws are standard for panel wiring.

Frequently asked questions

Where can I buy 3RV2021-1HA10-ZX95?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the closest functional second-source to 3RV2021-1HA10-ZX95?

The 3RV2021-1GA15 shares the same 45 mm frame, DIN-rail mounting, and Class 10 trip characteristic. The difference is in the trip setting range and interrupting ratings — verify motor FLA and fault current before substituting.

What are the key dimensions of 3RV2021-1HA10-ZX95?

Width is 45 mm, depth is 97 mm, height is 97 mm. Clearance above and below is 50 mm, sides 30 mm, forward/backward 0 mm.

Will 3RV2021-1HA10-ZX95 drop into a panel specified around 3RV2021-1GA15?

Yes, both use the same 45 mm wide SIRIUS frame and snap onto 35 mm DIN rail. No rewiring or enclosure changes are needed for the mechanical fit.
