Product details

Motor protection circuit breaker, 0.32 A, Class 10 — SIRIUS 3RV1021-0DA15-ZW96

No ground fault detection on this unit. The main contacts are rated for 100,000 mechanical operations typical. Auxiliary switch is present (transverse design), with zero auxiliary contacts for the main current circuit — the switch is integrated, not a separate block.

Mounting and panel integration — DIN rail, any position

Depth is 96 mm, width 45 mm, height 97 mm. Zero clearance needed at the sides or backwards. Front face is IP20 — touch-safe for panel interior, but not sealed against washdown or dust. Maximum operating altitude 2,000 m.

Termination and wiring — screw-type terminals

Solid conductor capacity: 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²). Stranded: 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²). Power dissipation at AC in hot operating state is 5.5 W. Auxiliary switch contacts rated: 1 A at 24 V, 0.5 A at 230 V, 0.15 A at 60 V. Rated insulation voltage 690 V.

Frequently asked questions

Where can I buy 3RV1021-0DA15-ZW96 and how do I get a price?

This part is sourced and quoted to order through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time.

What is 3RV1021-0DA15-ZW96's continuous current rating?

The continuous current rated value is 0.32 A. Trip class is Class 10, meaning it will trip within 10 seconds at 7.2x rated current — suitable for standard induction motor starting profiles.

What breaking capacity does 3RV1021-0DA15-ZW96 have at 400 V?

100 kA at 400 V AC. Also 100 kA at 240 V, 500 V, and 690 V AC. That's a high interrupting rating for a compact DIN-rail breaker — it handles severe fault currents without needing upstream fuses in most panels.

What is the depth of 3RV1021-0DA15-ZW96?

Depth is 96 mm. Width 45 mm, height 97 mm. Zero clearance required at sides or back.

What wire sizes does the 3RV1021-0DA15-ZW96 accept?

Solid: 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²). Stranded: 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²). Screw-type terminals on the main current circuit.
