Does anyone know a manufacturer of Electrical Door Interlocks for electical panels. The company that we usually buy ours from has upped their prices ten times since this time last year.
It is a solenoid with a clapper arm that keeps the door shut until power has been de-energized. Then the clapper latch opens and allows the door to be opened. We use them on galvanized NEMA 3R enclosures.
Thanks,
Robert
