The 3VA51 circuit breaker is designed for low voltage applications and incorporates a thermal-magnetic trip unit. It is rated at 70A with a high breaking capacity classified as class H, allowing it to handle up to 65kA at 480V and 25kAIC at 600Y/347. This model, devoid of lugs, has dimensions of 2 x 5.5 x 3.7 inches.
With a two-pole configuration, the circuit breaker provides reliable line protection through its TM210 trip unit, which offers fixed overload protection at 70A and a short-circuit protection setting of 10 times the rated current. The device is constructed for built-in applications and is suitable for DIN rail mounting, ensuring compatibility in various installation environments.
Additional specifications include an IP40 degree of protection and a rated voltage of 415V, making it suitable for a range of industrial applications. The circuit breaker does not feature an integrated earth fault protection or under voltage release, emphasizing its focused role in overload and short-circuit protection.
