Product Description

Special 3-pole and 4-pole high-voltage vacuum contactors for starting and dynamic braking of electric control equipment for mine hoists. After installing a mechanical interlock shaft between two vacuum contactors, mechanical interlocking can be achieved, and electrical interlocking can also be realized.

A 5-pole high-voltage vacuum contactor for the forward/reverse reversing cabinet of mine hoists. After installing a mechanical interlock shaft between two vacuum contactors, mechanical interlocking can be achieved, and electrical interlocking can also be realized, providing dual safety protection for phase reversal.

The above-mentioned high-voltage vacuum contactors are suitable for 7.2kV power systems. They are capable of frequent operation and offer advantages such as long mechanical life, high reliability, low failure rate, and strong breaking performance.
