Frozen Contactor Relay Model I-F

The Bramco I-F has been designed to detect a voltage leak across the contacts of any type of electrical switching device for the protection of personnel from electrical shock or the risk of electrical sparking.

Any type of deals can happen during one of the stages.



The I-F will detect a leakage of voltage across a switching device of 24 volts or more when the switching device is supposedly in the open or tripped position. A barrier is used in conjunction with this relay. The barrier is a three phase unit used to isolate high voltages from the detection equipment. As the barrier is a three phase unit leakage on any or all of the phases being monitored will detected and cause a trip. The detection circuit is non fail safe and energises on detection of leakage. The unit is internally powered from the power supply card.
