Siemens 3VA4150-5ED34-1AA0

The 3VA41 Circuit Breaker is a low-voltage device that provides reliable protection for electrical systems. This model supports a rated permanent current of 50A with a medium breaking capacity classified as Class M. It is engineered to handle 35kA at 480V and 18kA at 600V/347, ensuring effective circuit protection.

Equipped with a TM210 trip unit, this circuit breaker utilizes a fixed overload protection setting (Ir) of 50A and a fixed short-circuit protection (Ii) rated at 10 times the nominal current. The device is specifically designed with lugs installed on the load side only, making it suitable for naval applications with an operational temperature of up to 50°C.

In terms of physical dimensions, the circuit breaker measures 3 x 5.5 x 3.7 inches and is constructed as a built-in device with a fixed mounting technique. The IP40 rating ensures a degree of protection from solid objects, making it suitable for a range of industrial applications.
