Siemens 3VA2225-8HM32-0AA0

The 3VA22 circuit breaker is designed for low voltage applications, complying with IEC standards. It has a rated current of 250A and an exceptionally high breaking capacity of 150kA at 415V, making it suitable for various line protection scenarios.

This model incorporates the ETU330 electronic trip unit for precise overload and short-circuit protection with adjustable settings. Specifically, the overload protection current can be set between 100A and 250A, while the short-circuit release is adjustable from 1.5 to 10 times the rated current. Additionally, ground-fault protection can be configured between 0.2 and 1 times the rated current, with a time delay of either 0.1 or 0.3 seconds.

Featuring a robust IP40 protection rating, the device is intended for fixed installation and includes a connection with a lug terminal and nut keeper. The dimensions are 4.1 x 7.1 x 4.2 inches. This circuit breaker is suitable for mounting on DIN rails, providing versatility in installation.

Constructed for reliability, this device does not include a built-in motor drive or under-voltage release, ensuring a straightforward integration into existing systems. The main current circuit connections are made via a screw connection at the front side, facilitating ease of access during installation and maintenance.
