Abstract
A tripping solenoid is used in connection with a lockout relay and has an adjusting means for positioning a plunger end with respect to a coil of the solenoid to predetermine threshold voltage, reluctance, and response time to activation of the plunger by a magnetic field of the coil. A spring opposes movement of the plunger in a first direction toward a push rod which is separated from the plunger and mounted coaxially therewith.
