Siemens 3RV20314XA10 Molded Case Circuit Breaker

Siemens 3RV20314XA10 is a three-pole motor-protective circuit breaker from the SIRIUS 3RV2 family, designed to guard motors and motor-driven loads. It is a Class 10 device with a nominal current rating range of 49–59 A (In), suitable for motor circuits where fast protection within Class 10 tolerances is required. The unit is rated for up to 400 V AC and carries a short-circuit current rating (Icu) of 65 kA, enabling it to interrupt high fault currents typical of industrial motor applications. Wiring uses screw terminals for secure field connections, and the 3-pole configuration supports protection of three-phase motors. Common applications include protection for motors in panels, motor control centers, pumps, fans and compressors, where reliable motor protection and defined trip characteristics are required. This model is identified by Siemens as 3RV20314XA10, part of the 3RV2 Sirius motor protection MCCB lineup, delivering precise overload protection combined with short-circuit protection in a compact three-pole package.
