Product details

Motor-protection circuit breaker, 1 A, CLASS 10, 100 kA

Snap-on mounting onto 35 mm DIN rail per EN 50022; footprint is 45 mm wide × 97 mm high × 96 mm deep, fitting standard panel layouts with no side clearance required. Main circuit connections are screw-type terminals accepting 2× (1…2.5 mm²) solid or stranded, or 2× (2.5…6 mm²) — covers most motor feeder cable sizes up to 6 mm². IP20 protection on the front; suitable for enclosed panel use where no washdown or dust ingress is expected.

Key ratings in context

Power dissipation is 7.25 W total in hot operating state (2.4 W per pole), so panel thermal rise is modest — no forced cooling needed in most enclosures.

Frequently asked questions

What is the closest functional alternative to 3RV1021-0JA10-ZW97?

The 3RV1011-0GA10 is a smaller-frame SIRIUS motor-protection breaker with a lower breaking capacity; it will not drop into the same panel without checking the mounting rail and terminal clearances, as the 3RV1021 series has a 45 mm width versus the 3RV1011's 45 mm as well, but the 3RV1021 carries a higher 100 kA rating across all voltages.

What wire sizes does the 3RV1021-0JA10-ZW97 accept?

Solid and stranded conductors: 2× (1…2.5 mm²) or 2× (2.5…6 mm²); finely stranded with ferrule: same ranges.
