Lighting contactors that fail to closed position
Lighting contactors that fail to closed position
(OP)
I am working on a project that requires all lighting to fail to the on position but since my contactors that are owner furnished are mechanical held contactors if I lose control it will remain in the last position held.
My question is is there a way to make a mechanicaly held contactor do this or will I have to change contactors to electronicaly held contactors.

Problem is that if you need high current, it is difficult to find NC contacts with same rating as NO contacts. Most contactors above 10 - 16 A still have NC contacts rated at 10 A.
