This weekend I decided to pull all MCE contactors ... the stock I bought to try keep the site going ... I will be returning.
It is just not worth it ... everytime I loose a contactor ... the ripple effect in the control circuits using control transfomers with low VA ratings is far out weighs the couple of rand saving using MCE ... even if I was the maintenance electrician at the factory ... the machine downtime ... production losses ... all this requires consideration.
After wasting many hours trying to find a solution to protect the transformers ... I learnt a lot but at the end of the day ... not worth hassle.
The blue flash as the contactor makes and breaks ... the high inrush current ... the higher running current compared to other contacotors I researched ... may not be an issue if you have a neutral from the DB sealed the decision.
Maybe the product is good for other applications ... as mentioned by others ... but not in my case.
You live and learn.
