Theory of Operation

Each contactor contains a permanent magnet built into its struc-

ture that will maintain the contactor in its energized state indefi

-

nitely without using control power. When energized, DC voltage 

is applied to produce a magnetic field that reinforces the polarity 

of the permanent magnet and the contactor closes. Immediately, 

the current to the coil is disconnected by the coil clearing aux-

iliary contact. In order to open the contactor, it is necessary to 

create a field through the OFF coil in the reverse direction to the 

permanent magnet. This momentarily cancels the magnetic at-

traction and the contactor drops out.

Magnetically latched CLM lighting and heating contactors can 

control tungsten, fluorescent and metal vapor lamp or heating 

loads. (Table 1 below shows the voltage and current rating for 

various loads). Each contactor and its associated load should be 

protected against short circuits by a suitable branch circuit pro-

tective device selected in accordance with the National Electric 

Code (NEC).

Care should be taken when servicing that leads do not be-

come changed from their factory installed terminals, or im

-

proper operation and possibly permanent damage to the 

contactor could result.

CAUTION: Do not apply AC voltage directly to the coil 

terminals of this device! The permanent magnet will be 

demagnetized and the rectifier will be damaged if alter

-

nating current or wrong polarity direct current is ap-

plied directly to the coil.

Each CLM contactor has an electronic control module 

“CLMKCMR” which is used to energize and close the 

contactor and for the release circuit. It is designed for short 

time actuation of 1-3 cycles only. All coils are designed with 

a small wattage resistor in addition to a diode at coil voltages 

higher than 120 volts. Remote solid state switching devices 

have ‘off state’ leakage currents. They may also pass utility 

transient voltages through to the device electronics. The low  

level ‘off state’ voltages are insufficient to actuate the contactor 

but large enough to burn out the resistors. Normal actuating 

voltages are quickly disconnected from the coils and control 

module by the latch clearing contacts. Coil and module 

failures are possible when used with solid state relays and 

PLC outputs. 24-volt systems are ok to use, but 120 volts 

and above should be discouraged. If higher voltages cannot 

be avoided, an interposing relay should be used.
