Product details

It carries a continuous current rating of 5 A and a trip class of CLASS 10, meaning it will trip within 10 seconds at 7.2× the set current, matching the thermal characteristic of standard induction motors during start-up. Rated for use up to 690 V, its breaking capacity is 100 kA at 240 V, 400 V, and 500 V AC, dropping to 6 kA at 690 V. At 400 V it is rated for 1.5 kW motor load, which is the typical sizing for a small pump or fan motor. It includes phase failure detection, which is critical for preventing single-phasing damage on three-phase motors. No ground fault detection is built in — that would require an add-on module or separate GFCI.

Accepts solid or stranded conductors: 2x (1 … 2.5 mm²) and 2x (2.5 … 6 mm²), or AWG 14–10. The dual-wire capacity per terminal is useful for daisy-chaining control power or looping through the line side. Dimensions: 96 mm deep, 97 mm tall. Zero clearance required at the back or sides, so it fits tight against the backplane or adjacent devices.

Shock rated at 25g / 11 ms. Surge voltage resistance at 6 000 V. Power dissipation is 7.25 W total in hot operating state (2.4 W per pole). RoHS compliance date is 01.05.2012.

Frequently asked questions

How do I get current pricing and availability for 3RV1021-1FA10-ZW97?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time through our independent distribution channels — we source and quote to order.

What is 3RV1021-1FA10-ZW97's listed depth?

The listed depth is 96 mm, with zero clearance required at the back or sides for mounting.

What compliance documentation does this brand provide for 3RV1021-1FA10-ZW97?

RoHS compliance is documented with a substance prohibitance date of 01.05.2012. The product carries IP20 front protection and is designed to IEC/EN 60947 standards for motor protection circuit breakers.

Will 3RV1021-1FA10-ZW97 drop into a panel specified around 3RV2021-1FA15 without rewiring?

The 3RV1021-1FA10-ZW97 uses the same 45 mm width and screw-type terminals, so it fits the same DIN-rail footprint and accepts the same conductor sizes. However, the 3RV2021-1FA15 is a different rating variant — verify the continuous current and trip class match your motor FLA before substituting.
