ABB’s broad range of protection devices for equipment and installation protect against short circuit, overload, phase loss and unbalance protections. It set the standard in sustainable performance and reliability, and shape your daily life. Manual motor starters save costs, space and ensure a quick reaction under short-circuit condition by switching the motor off within milliseconds in almost every situation including hazardous areas. The Circuit breaker for transformer protection will provide overcurrent protection on the primary side of the transformer. This avoids expensive protection on the secondary side.
