Siemens 3VA4120-4ED34-0AA0

The 3VA41 circuit breaker is designed for low voltage applications and incorporates a thermal-magnetic trip unit, classified as Class S for its breaking capacity. With a rated voltage of 690V and a permanent current rating of 20A, it effectively provides line protection. The unit includes lugs installed solely on the load side, enhancing installation efficiency.

Measuring 3 inches in width, 5.5 inches in height, and 3.7 inches in depth, this built-in device is suitable for DIN rail mounting. Its configuration does not support motor drive integration, and it lacks earth fault protection. The device is equipped with a rocker lever control element and does not indicate switched-off status. The short-circuit protection is fixed at 15 times the rated current, ensuring robust overload protection.
