Product description

The reversing contactor BH 9255 is used to reverse the direction of 3-phase asynchronuos motors by switching 2 phases (L1 and L2). An electrical interlocking disables the control of both directions at the same time. The reversing contactor has a short on and off delay time. When reversing the phases a switchover delay is guaranteed. The motor current is monitored in phase L1. If the current rises above the tripping value the device is able to switch off the motor.
