Product details

The Siemens 3RV1021-1HA10-ZX95 is a SIRIUS motor protection circuit breaker rated for 8 A continuous current with a Trip Class 10 thermal-magnetic trip curve, sized for a 3 kW motor at 400 V AC.

Compared to the 3RV1011-1HA10, the 3RV1021-1HA10-ZX95 shares the same 45 mm width and 35 mm DIN-rail snap-on footprint, so it drops into a panel specified around the older sibling without rewiring. The key difference is the 3RV1021's higher breaking capacity — 100 kA at 400 V versus the 3RV1011's lower rating — making it the better fit for a panel with a high available fault current.

The 45 mm width and 96 mm depth fit a standard 45 mm-wide DIN-rail slot — no extra side clearance needed (0 mm backwards, 0 mm at the side). Screw-type terminals on both main and auxiliary circuits accept solid or stranded wire: 2x (1…2.5 mm²) and 2x (2.5…6 mm²), or AWG 14–10.

Frequently asked questions

Where can I buy 3RV1021-1HA10-ZX95 and how do I get a price?

The 3RV1021-1HA10-ZX95 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.

Will 3RV1021-1HA10-ZX95 drop into a panel that was specified around 3RV1011-1HA10 without rewiring?

Yes, the 3RV1021-1HA10-ZX95 shares the same 45 mm width and 35 mm DIN-rail snap-on footprint as the 3RV1011-1HA10, so it drops into the same panel slot without rewiring. The terminal wire ranges are identical.

What compliance documentation does this brand provide for 3RV1021-1HA10-ZX95 (RoHS, REACH, UL, IEC)?

The part carries a substance prohibition date of 01.05.2012, confirming RoHS compliance from that date. Siemens provides declarations for RoHS, REACH, UL, and IEC via its standard documentation portal.
