Product details

SIRIUS 3RV1021-0FA15-ZW98 — motor protection breaker, 0.5 A, CLASS 10

It carries a continuous current rating of 0.5 A and a CLASS 10 trip characteristic, meaning it disconnects within 10 seconds at 7.2× rated current — fast enough to protect standard induction motors during locked-rotor conditions without nuisance tripping on normal starts. The unit also includes phase failure detection, so a lost phase on the line side will trip the breaker before the motor single-phases.

Any mounting position is allowed. Terminals accept solid wire 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²), or stranded 2x (1...2.5 mm²) and 2x (2.5...6 mm²).

Frequently asked questions

Where can I buy 3RV1021-0FA15-ZW98 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 3RV1021-0FA15-ZW98's listed depth?

Depth is 96 mm, with a width of 45 mm and height of 97 mm.

What wire sizes does the 3RV1021-0FA15-ZW98 accept?

Solid wire: 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²). Stranded wire: 2x (1...2.5 mm²) and 2x (2.5...6 mm²). Main circuit uses screw-type terminals.

Will 3RV1021-0FA15-ZW98 drop into a panel specified around 3RV1011-0GA10?

Both are SIRIUS motor protection breakers on the same 45 mm DIN-rail footprint, so mechanical fit is the same. The 3RV1021-0FA15-ZW98 is a 0.5 A CLASS 10 device with 100 kA SCCR at 400 V; the 3RV1011-0GA10 is a different current rating and trip class. Verify the motor FLA and trip class match before substituting.
