Product details

SIRIUS 3RV1031-4EA15-ZX95 — motor-protective circuit breaker, 32 A, CLASS 10

The Siemens 3RV1031-4EA15-ZX95 is a SIRIUS motor-protective circuit breaker rated for 32 A continuous current and 15 kW at 400 V AC-3. Breaking capacity is 100 kA at 240 V AC, 50 kA at 400 V AC, 10 kA at 500 V AC, and 4 kA at 690 V AC.

Mounting and integration — DIN rail, any position

Shock rated to 25g / 11 ms, so it holds up on mobile equipment or near rotating machinery. Main circuit terminals are screw-type box terminals accepting solid 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²), or stranded 2x (0.75…25 mm²) and 1x (0.75…35 mm²). Auxiliary and control circuit terminals are also screw-type. The auxiliary switch is a transverse design and is field-installable as a product extension.

Front-face protection class IP20. RoHS compliance date 07/01/2006. Power dissipation in hot operating state is 19 W.
