Merlin Gerin NS250 contactor not working
Merlin Gerin NS250 contactor not working
(OP)
Hi, I have a merlin gerin compact NS250N breaker dealing with the power changeover between generators and shore power on my boat. When I change manually by pressing the buttons on the front of the breaker there is no problem. When I try to do it automatically the contacts try to close and i get a buzzing for a few seconds which then stops and the contacts stay open. I have replaced the main breaker and the front end control but it still does it. Is it a problem with the breaker or am I looking in the wrong place? Hope someone can help me
