Siemens 3VA2216-5JP42-0AA0

The 3VA22 4P 160A 55KA ETU5-LSI NUT is designed for low voltage applications as a molded case circuit breaker. It supports a rated voltage of up to 690V and is equipped with a class M breaking capacity, making it suitable for medium-voltage environments. The device features an overload protection setting adjustable from 63A to 160A, with a short-circuit protection range of 0.6 to 10 times the rated current.

With a compact design measuring 5.5 x 7.1 x 4.2 inches, it includes a nut keeper for secure connections via lug terminals. This breaker is built to meet IP40 protection standards, ensuring reliable operation in various conditions. It is suitable for DIN rail mounting, which facilitates installation in control panels.

Notably, the ETU550 electronic trip unit provides advanced monitoring capabilities, enhancing safety and operational efficiency. The lack of integrated earth fault protection and under voltage release indicates a focus on specific applications where these features are not required.

Overall, this circuit breaker combines robust construction with essential functionalities, making it a critical component in electrical distribution systems.
