Product details

Motor protection circuit breaker, 3.2 A, CLASS 10, 100 kA

The Siemens SIRIUS 3RV1021-1DA15-ZW96 is a motor protection circuit breaker rated for a continuous current of 3.2 A with a CLASS 10 trip characteristic, meaning it will trip within 10 seconds at 7.2× the set current — fast enough to protect standard induction motors during a stall or locked-rotor event without nuisance tripping on normal starting inrush. Breaking capacity is 100 kA at 240 V, 400 V, and 500 V AC, dropping to 8 kA at 690 V AC.

Screw-type terminals for the main current circuit accept solid conductors: 2×(0.5…1.5 mm²) and 2×(0.75…2.5 mm²). Stranded conductors: 2×(1…2.5 mm²) and 2×(2.5…6 mm²). The auxiliary switch is transverse design; the breaker includes an auxiliary switch (yes) but no auxiliary contacts for the main circuit (0). No ground-fault detection. Trip class CLASS 10 matches most standard motor starting profiles. Shock rated at 25g / 11 ms. Mounting position any.

Frequently asked questions

What is the breaking capacity of 3RV1021-1DA15-ZW96 at 400 V?

100 kA at 400 V AC, which is the same rating at 240 V and 500 V AC. At 690 V AC it drops to 8 kA.

Where can I buy 3RV1021-1DA15-ZW96?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the trip class of this breaker?

CLASS 10 — it will trip within 10 seconds at 7.2× the set current, suitable for standard motor starting.

Does 3RV1021-1DA15-ZW96 include phase failure detection?

Yes, phase failure detection is built in. It does not include ground-fault detection.
