In the capacitor compensation system, because the capacitor is often automatically switched, it is necessary to use the contactor as the frequent operation of the circuit breaker. So, what technical requirements do qualified contactors need to meet?The operating voltage and release voltage of th

Why do mechanical interlocking contactors have noise and poor contactMechanical interlock contactor is blocked, poor contactCause analysis: 1. Reaction spring falls off, contact spring falls off,2. Contact surface oxidation,3. Foreign bodies on the contact surface.4. Mechanical c
