Neutral contactor rating dxtdh

Which method is best for switching the neutral: 3-pole transfer switches with overlapping neutral contacts or 4-pole switches? The answer may surprise you. You want to preserve the integrity of your ground fault protection system without compromise, so what do you do when it comes to switching the neutral? Among many benefits, you've heard 3-pole transfer switches with overlapping neutral contacts Cressall manufactures neutral earthing resistors for voltages up to 132kV and for any current and time rating. Earthing resistors are a key component of the earth fault protection scheme in the majority of medium voltage electricity generation and distribution systems. When we design or replaced the magnetic contactor for motor starter or for others application,the important point is how to sizing the size of magnetic contactor.This is critical point because if we not sizing properly,it can cause a serious damage and our application maybe failure to perform in perfect condition.
