mcb circuit breaker Long life , high reliability:

Contactor life and reliability is mainly composed of a coil and contact life decisions. Because of the traditional AC contactor coil and core work when it may have a fever, especially voltage, mcb circuit breaker‍ easily lead to fever current, the magnetic gap increases the coil burned, while the permanent magnet AC contactor coil may be burned does not exist. Contact ablation mainly by opening, closing arc generated when due. Compared with conventional contactors mcb circuit breaker, the role of permanent magnet AC contactor in the closing, in addition to the same electromagnetic force, but also with permanent force, thus closing speed is much faster than traditional AC contactor, after testing, permanent magnet AC contactor closing time is generally less than 20ms, while the traditional contactor closing speed is generally about 60ms. Sub-gate, in addition to the permanent magnet AC contactor opening action of the spring, but also has the effect of magnetic repulsion force, these two effects makes opening speed faster than the traditional number of contacts, after testing, permanent magnet AC contactor points opening time is generally less than 25ms, while the traditional contactor opening speed is generally more than 80ms. In addition, the heating coil and core capacity will reduce the main contact, suction voltage fluctuations caused by insufficient or tremor causes fever traditional contactor main contacts, arcing or welding. Permanent magnet AC contactor contact life compared with conventional AC contactor contacts, under the same conditions Voltage stabilizer‍ improve life 3-5 times.

. ⑥ anti-electromagnetic interference:

Permanent magnet AC contactor using magnetic circuit is completely sealed,, in the course will not be subject to external electromagnetic interference, nor will the external electromagnetic interference.

. ⑦ intelligent anti Akira power:

Electronic control module controls the release voltage value can be delayed by a certain time and then send a reverse pulse current to achieve low voltage power-off delay time release or release it from the motor control voltage fluctuations (Akira power) and jump stop, so as to maintain stable production system. Especially the device type continuous production enterprises can reduce venting and resume production of electricity, steam, natural gas Inverter Power Supply‍ consumption and labor costs, equipment repairs and other damage.
