Siemens 3VA1120-4ED36-0AA0

The 3VA11 circuit breaker is designed for low voltage applications, featuring a thermal-magnetic trip unit that provides reliable line protection. This unit operates within a rated voltage of 690V and has a high breaking capacity classified as Class S, handling up to 36kA at 415V. The device is equipped with a TM210 trip unit, characterized by a fixed overload protection setting (Ir) of 20A, and a short-circuit protection setting (Ii) that is 16 times the rated current.

With dimensions of 3 x 5.1 x 3.5 inches, the breaker supports a clamp connection method and is capable of DIN rail mounting. It features a built-in device construction with a degree of protection rated at IP40, ensuring durability in various environments. The absence of integrated earth fault protection and under-voltage release highlights its specialized design for specific applications.

This device is constructed for fixed installation, offering an adjustment range for undelayed short-circuit release up to 320A, making it suitable for a range of industrial contexts.
