Siemens 3RV2711-1ED10 Sirius Modular Circuit Breaker

Siemens SIRIUS 3RV2711-1ED10 is a compact S00-size three-pole motor-protection circuit breaker in the SIRIUS 3RV2 family, engineered for system protection in three-phase circuits up to 690 V and carrying UL 489 and CSA C22.2 No. 5-02 approvals for reliable, factory-floor use.

This DIN-rail mounted unit uses screw terminals and provides a fixed 4 A nominal current rating, aligning with Siemens' modular 3RV2 protection scheme for motors and other equipment in industrial control panels.

Key electrical specs include 690 V insulation, 6 kV surge withstand, IP20 front protection, and optional lateral or transverse auxiliary switches that can be ordered to suit control wiring and diagnostics.

Power loss typically runs around 7.25 W total (2.4 W per pole) in normal operation, reflecting its thermal-magnetic trip design and suitability for motor-protection roles in three-phase systems.
