Siemens 3VA2163-6HM42-0AA0

The 3VA21 4P circuit breaker integrates an electronic trip unit (ETU330) and is designed for low-voltage applications. With a rated permanent current (Iu) of 63A, it offers exceptional performance and reliability. This device supports a breaking capacity of 85kA at 415V and 2.5kA at 690V, making it suitable for a variety of electrical protection needs.

Constructed for a 4-pole configuration, the breaker includes features such as adjustable overload protection (Ir=25A to 63A) and short-circuit protection (Ii=1.5 to 12 times In). It also provides ground-fault protection adjustable between Ig=0.25 to 1 times In with a time delay of tg=0.1/0.3s. The design accommodates convenient installation with a front-side connection for the main current circuit and is compatible with DIN rail mounting.

Additional specifications include an IP40 degree of protection, indicating resistance to dust and water ingress, and the option for motor drive integration. This model does not include a switched-off indicator, and the control element is a rocker lever. Notably, the 3VA21 4P circuit breaker is constructed as a built-in device, ensuring a fixed installation technique.
