Siemens 3VA1132-3GE42-0AA0

The 3VA11 frame circuit breaker is tailored for low voltage environments, adhering to IEC standards. It is equipped with a thermal-magnetic trip unit and operates at a rated voltage of 690V. The device has a breaking capacity classified as N, with Icu rated at 25kA when measured at 415V. The trip unit, TM220, allows for adjustable overload protection settings from 22A to 32A, ensuring precise response to varying load conditions.

Notably, the circuit breaker features a front-side connection for the main current circuit and utilizes screw connections for electrical integration. The dimensions of the unit are 4 inches in width, 5.1 inches in height, and 3.5 inches in depth, making it suitable for space-constrained installations. Additionally, the device lacks integrated earth fault protection and under voltage release, confirming its specific application focus.

For installation, it is important to note that this circuit breaker is not suitable for DIN rail mounting but includes a connection with a lug terminal and nut keeper for secure installation. The rated short-circuit breaking capacity is consistent at 25kA at a frequency of 50Hz, confirming its operational reliability.
