Specification & Description
The Siemens 3RV1331-4HC10 is a robust circuit breaker designed for starter combination applications, ensuring reliable protection and management of high-capacity motors and systems. This circuit breaker, part of the SIRIUS product family, is engineered to handle a rated current of 50 A and has a standard breaking capacity with a short-circuit release of 650 A. It is suitable for use in systems with operating voltages up to 690 V and can withstand a rated short-circuit breaking capacity (Icu) of 50 kA at 400 V, making it an excellent choice for industrial environments where high performance and durability are required.
The device features a three-pole design for main current circuit control and is equipped with screw-type terminals with box terminals for secure and reliable connections. Its compact dimensions allow for efficient use of space within control cabinets, and it can be mounted easily onto a 35 mm standard mounting rail according to DIN EN 50022. The 3RV1331-4HC10 is designed to operate within a wide range of ambient temperatures, from -20°C to +60°C, ensuring consistent performance even in demanding conditions.
With a mechanical service life of typically 50,000 switching cycles, this circuit breaker is built to last and maintain its functionality over time. It also features a protection class of IP20 on the front, providing a basic level of protection against solid objects. The 3RV1331-4HC10 is a discontinued product, and its preferred successor is the SIRIUS 3RV2 series, which continues to offer the same high standards of protection and reliability for industrial applications.
