Siemens 3RV20314WA15 Circuit Breaker for Motors S2 Class 10 42-52A Screw 1NO/1NC 3RV2 Series

Product Description

The SIEMENS 3RV20314WA15 is a circuit breaker for motor protection, size S2, class 10 with A-release 42...52A and N-release 741A. It features a screw terminal and standard breaking capacity with a transverse auxiliary switch 1NO+1NC. Suitable for operation in IT systems, this device minimizes energy losses and reduces inherent power loss, leading to less heating of the control cabinet.

• Minimizes energy losses through optimization of the bimetal trip units
• Reduces inherent power loss and heating of the control cabinet
• Features a screw terminal and standard breaking capacity with a transverse auxiliary switch 1NO+1NC

Product Highlights

The SIEMENS 3RV20314WA15 circuit breaker provides reliable motor protection with efficient energy use and versatile application.
