ASAP Semiconductor LLC
Relays is de-energized, ensuring the presence of an air gap within the circuit. When current is induced to the relays, the coil will become energized and will produce a magnetic field. This magnetism attracts the armature assembly, adjusting the positioning of the movable contacts to either make or break a connection. Upon the loss of power, the magnetic field will drop and the armature will return to its de-energized position with the aid of the spring so that contacts can readjust. While such methods...

S. Himmelstein & Company
OVERLOAD/OVERRANGE - WHAT’S THE DIFFERENCE? Two easily overlooked, yet extremely critical parameters when evaluating and specifying torque transducers are - Mechanical Overload Rating and Electrical Overrange. Each is important, but often confused and misunderstood. Overload - represents a mechanical safety factor for the sensor element. Normally expressed as a percentage of the sensor full scale rating, it is the maximum load limit of the sensor before yield or physical deformation. S Himmelstein and Company products are available... (read more) -

Discussion on ¿Excess-current protection by over-current relays on medium-voltage circuits¿ before the Installations Section, 3rd May, 1945
With a thermal relay this is usually quite correct, but with magnetic overload relays having oil dashpots certain specifications call for adjustments of .the time-lags; in most cases this is done by means of a leak valve.
