Linkage mechanism mounted on the contactor of the permanent magnet fixed polarity

Linkage mechanism air circuit breaker on the contactor of the permanent magnet fixed polarity, and curing the base of the contact on the soft magnetic interaction variable polarity, so as to pull, to maintain and release purposes. The variable soft magnetic polarity is cured together with an electronic module electric meter a dozen to two dozen milliseconds forward and reverse pulse current, and to produce different polarities. According to the site needs, with control mcb circuit breaker to control the release of the set voltage value, can also be a delay before issuing reverse pulse current to reach the low-voltage power-off delay release delayed release or purpose to control the motor Akira power from the grid and a jump stop, so as to maintain the stability of the production system.
