Siemens 3VA1163-5GF42-0AA0

The 3VA11 4P 63A 55KA circuit breaker features a thermal-magnetic trip unit, specifically designed for low voltage applications under IEC standards. With a rated voltage of 690V and an impressive breaking capacity of 55kA at 415V, this device is equipped to handle significant short-circuit conditions. The TM240 trip unit allows for adjustable overload protection, with settings ranging from 44A to 63A, and a short-circuit protection factor of 5 to 10 times the rated current.

Connection is facilitated through a lug terminal with a nut keeper, ensuring secure and reliable electrical contact. The dimensions of this built-in device are 4 inches in width, 5.1 inches in height, and 3.5 inches in depth. The unit is constructed with an IP40 degree of protection, making it suitable for various industrial environments. Notably, it does not come with an integrated earth fault protection or under voltage release, emphasizing its specific functional design for line protection applications.
