Product details

The Siemens SIRIUS 3RV1021-0GA15-ZW96 is a motor protection circuit breaker rated at 0.63 A continuous current with a Trip Class 10 thermal-magnetic trip curve, sized for small motor loads up to 0.18 kW at 400 V AC.

Termination & Wiring

Main circuit and auxiliary/control circuit connections use screw-type terminals, accepting solid conductors 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²), and stranded conductors 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²). AWG equivalents for main contacts are 2x (14... 10). Auxiliary switch is transverse design and field-addable.

Environmental & Mounting

Shock resistance is 25g / 11 ms. Mounting position is any. IP20 protection on the front, suited for enclosure installation where the operator does not contact live parts. Dimensions: 45 mm wide, 97 mm high, 96 mm deep.

Frequently asked questions

What wire sizes does 3RV1021-0GA15-ZW96 accept?

Screw terminals accept solid 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²), and stranded 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²).
