Specification & Description
The Siemens 3RV1331-4EC10 is a robust circuit breaker designed for industrial applications requiring reliable protection and control. This three-pole device is engineered to handle a rated current of 32 A and an operating voltage up to 690 V ac, making it suitable for a wide range of electrical circuits. Its DIN Rail mount design allows for easy installation within control panels, and with a standard breaking capacity of 50 kA at 400 V, it offers substantial protection against short-circuit currents.
Constructed to meet the demands of modern industrial environments, the 3RV1331-4EC10 features a compact form factor with dimensions of 55 x 149 x 140 mm, ensuring it does not occupy excessive space within electrical enclosures. The circuit breaker is designed without an overload protection function, focusing on short-circuit protection, and it does not include an auxiliary switch or undervoltage release mechanism as part of its standard configuration. However, it does allow for the addition of an auxiliary switch if needed.
The device's screw-type terminals with box terminals provide a secure and reliable connection for both solid and stranded conductors, accommodating a range of wire sizes for flexible installation options. The 3RV1331-4EC10 is also characterized by its mechanical durability, with a mechanical service life of typically 50,000 switching cycles, ensuring long-term reliability and reduced maintenance needs.
This circuit breaker is a discontinued product, and its preferred successor is the SIRIUS 3RV2 series. However, for those in need of this specific model for compatibility or replacement purposes, the 3RV1331-4EC10 remains a trusted choice for safeguarding electrical systems against the damaging effects of short-circuit events.
