Siemens 3RV2011-1EA10 Motor Protection Circuit Breaker

Siemens SIRIUS 3RV2 motor protection circuit breaker, model 3RV2011-1EA10, is a 3‑pole, size S00 device designed for motor protection in 690 VAC systems. It provides thermomagnetic protection with an A‑release rated for 2.8–4 A (continuous) and a separate N‑release rated at 52 A, with a continuous current rating of 4 A, making it suitable for protecting small to medium motors from overload and short circuits. The unit includes an auxiliary switch and uses screw terminals for simple field connections, enabling easy integration into standard motor control circuits. It offers front IP20 protection, 6 kV surge voltage resistance, and 6 kV impulse withstand, supporting reliable operation in industrial environments. Mechanical service life is specified around 500 switching cycles, with total power loss approximately 6 W (2.4 W per pole) at rated current, reflecting its compact, energy-conscious design. This 3RV2011-1EA10 variant is part of the SIRIUS 3RV2 family and is intended for motor protection applications where a compact, high-visibility disconnector with a thermal‑magnetic trip is required, compatible with standard Siemens motor control schemes and standard switching capacity in 690 V networks.
