For the flameproof vacuum solenoid, the product is used to absorb and consume electromotive force electrical disconnect of inductive loads, which can effectively prevent the burn out switch contact, and can effectively restrain the operation of instant oscillation and high frequency voltage and current to voltage waveform is slow, steep amplitude decrease, coupled with the resistance the damping effect, the high frequency oscillation decays rapidly. Resistance capacitance is divided into two voltage levels 600/380V, 1140/600V, the price is also different. Vacuum electromagnetic starter suitable for voltage level to 1140V.
