Advanced control technologies and long life

As a result of high-performance permanent magnetic materials and the use of high-end microprocessor controller designed by the company's proprietary control technology, permanent magnetic actuator coil drive power adjustment to get the best breaker points, closing the curve and make points, co-the end of the effective realization of the soft landing, a significant reduction in the mechanical impact, greatly improves the life of mechanical components, but also eliminates the process of operation, the dynamic and static conductive rod accumulated due to mechanical collision caused by mechanical deformation and ultra-stroke, open from change. Users do not need to make further adjustments. Performance of the circuit breaker has reached unprecedented heights in the industry, using a period of 20 years, the normal load current during operation, maintenance, adjustment-free. Place more frequent operation of the circuit breaker to highlight the superiority.

Simple structure, high reliability

ith a new design of permanent magnetic actuator, large output, light weight, easy to operate, reliable action. Reduce the number of permanent magnet machine parts than the original spring mechanical quantity more than 90% in the sub-closing position no mechanical fasteners. In the closed position, the use of a permanent magnet moving, low-impedance path static magnetic core provided will be kept in closed position the plunger. In the open position, by opening spring retained. Simple mechanical transmission, vacuum interrupter touched movement balance, no Resist, resist points and misuse together, misclassification phenomenon. Manual dexterity easy opening.

Featured

Power applicable ability, different external AC / DC power supply via the controller through modern technology conversion, the working mechanism in case the optimum voltage, the operating power is small.
The controller has provided 'anti-jump', 'free trip' and perfect 'lockout protection' function as the circuit breaker.
Controller software upgrades 'online programming', so that the controller can easily meet the growing demand for protection.
