Siemens 3VA2063-7HN42-0AA0

The 3VA20 4P circuit breaker is designed for low voltage applications, adhering to IEC standards. It offers a very high breaking capacity, classified as Class C, with an Icu rating of 110kA at 415V and 2kA at 690V. This model supports a rated permanent current of 63A with adjustable overload protection between 25A to 63A. The short-circuit protection is set between 1.5 to 10 times the rated current, while the instantaneous short-circuit protection is set at 12 times the rated current.

Constructed for robust line protection, this device features a connection with a lug terminal and includes a nut keeper kit. The dimensions are 5.5 inches in width, 7.1 inches in height, and 4.2 inches in depth. It is suitable for mounting on DIN rails, and it incorporates a built-in construction technique for easy integration into electrical panels.

Additional specifications include an IP40 degree of protection, ensuring resistance against dust ingress, and it is not equipped with an integrated earth fault protection. The circuit breaker utilizes a rocker lever as the type of control element and does not have an under-voltage release integrated.
