Description
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).

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.

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
40
have 'off state' leakage currents. They may also pass utility
40
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
10A
and above should be discouraged. If higher voltages cannot
28VA
be avoided, an interposing relay should be used.
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.
