Product details

It carries a continuous current rating of 1.6 A and a trip class of CLASS 10, meaning it will trip 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. Breaking capacity is 100 kA across the board at 240 V, 400 V, 500 V, and 690 V AC, so it can be applied on high-fault-current panels without worrying about series rating coordination downstream. This breaker catches that condition.

Any mounting position is permitted. Zero clearance required at the sides or rear for heat dissipation. Main circuit terminals accept solid conductors 2×(0.5…1.5 mm²) and 2×(0.75…2.5 mm²), or stranded 2×(1…2.5 mm²) and 2×(2.5…6 mm²). AWG equivalents for the main contacts are 2×(14…10). Auxiliary and control circuits use screw terminals as well.

RoHS compliance is documented with a substance prohibition date of 01.05.2012, indicating it meets the EU RoHS directive effective from that date.

Shock resistance is 25 g for 11 ms, so it holds calibration and mechanical integrity under moderate vibration and impact in industrial environments. Maximum operating frequency in AC-3 duty is 15 operations per hour, which limits its use in high-cycling applications like rapid reversing or jogging.

Frequently asked questions

What is the breaking capacity of the 3RV1021-1AA15-ZW97 at 400 V?

100 kA at 400 V AC, and the same 100 kA rating applies at 240 V, 500 V, and 690 V AC.

Will the 3RV1021-1AA15-ZW97 drop into a panel specified for the 3RV1011-1AA15?

Both are 45 mm wide SIRIUS motor protection breakers with similar mounting on 35 mm DIN rail, so the physical footprint and rail clip are compatible. However, the 3RV1021-1AA15-ZW97 carries a 1.6 A continuous rating versus the 3RV1011-1AA15's different rating — verify the motor FLA matches before substitution. The terminal wire ranges also differ slightly; check the specific conductor sizes on your existing wiring.

How do I get pricing and availability for the 3RV1021-1AA15-ZW97?

Submit an RFQ through this listing. The part is sourced to order through independent distribution; current pricing and stock status are confirmed at quote time.

What compliance documentation is available for the 3RV1021-1AA15-ZW97?

RoHS compliance is documented with a substance prohibition date of 01.05.2012. The product is designed to meet applicable IEC/EN standards for motor protection circuit breakers, including the SIRIUS series certification. Specific UL/CSA documentation should be requested with the order.
