Siemens 3VA5160-6EC31-0AA0

The 3VA51 circuit breaker is designed to provide reliable line protection with a rated current of 60A and a breaking capacity of 65kA at 480V. This device features a thermal-magnetic trip unit (TM230) with fixed overload protection (Ir) set at 60A and adjustable short-circuit protection (Ii) ranging from 5 to 10 times the rated current. The circuit breaker operates at a maximum rated voltage of 690V and is suitable for installation in various applications.

Constructed to comply with high standards, the device is rated for IP40 protection, ensuring its functionality in diverse environments with operating temperatures spanning from -25°C to 70°C. Notably, this circuit breaker does not include lugs and has dimensions of 3 inches in width, 5.5 inches in height, and 3.7 inches in depth. The 3VA51 model is equipped with a built-in technique for fixed installation, making it compatible with DIN rail mounting.

Additional specifications include a mechanical service life of approximately 20,000 operating cycles and an electrical endurance of 8,000 cycles at AC-1 under certain voltage conditions. For applications requiring integrated earth fault protection or under-voltage release, this model does not support such features.
