Siemens SIRIUS Innovation Motor Protection Circuit Breaker, 42 to 52A Current Rating - 3RV2 Series - 3RV2031-4WA10
Use this circuit breaker from Siemens to protect your 3-phase motor. It automatically cuts off current in the event of overload or unwanted interruption and stops your motor from running in seconds. This prevents damaged parts and minimises maintenance downtime. The breaker is part of the Sirius Innovation range of switching devices for load feeders, including contactors and both overload and current monitoring relays. It has a slim design, with a width of 55mm, and a screw terminal to mount quickly to any flat surface in your control cabinet. It can also be snap-fitted onto a standard 35mm DIN rail.
• High-capacity control voltage of 42 to 52A
• Operating temperature can reach +60°C without affecting performance
• Top and bottom electrical connectors offer flexibility during installation

What does Class 10 trip class refer to?
Class 10 tripping means the circuit breaker will trip in 10 seconds or less when six times the maximum thermal current rating is reached. This quick response means the unit improves workplace safety and limits potential damage to connected components.
