Siemens 3VA1120-3ED16-0AA0

The 3VA11 circuit breaker is designed for low voltage applications, offering a thermal-magnetic trip unit for effective line protection. With a rated current of 20A and a breaking capacity classified as low (Class N), it ensures reliable operation in various settings. The device has a rated short-circuit breaking capacity (Icu) of 25kA at 240V, making it suitable for environments requiring robust protection against electrical faults.

Features include a fixed overload protection (Ir) set at 20A and a short-circuit protection (Ii) calculated as 16 times the rated current. The connection is facilitated through a box terminal with a steel wrap-around lug, ensuring secure and efficient electrical connectivity. The dimensions of the device are compact, measuring 1 x 5.1 x 3.5 inches, which allows for versatile installation options.

Additionally, the circuit breaker is constructed as a built-in device with a front-side connection for the main current circuit. This model does not support DIN rail mounting. Notably, it is IP40 rated, providing adequate protection against dust and moisture ingress, which is essential for maintaining performance in industrial environments.
