General

	Type CLM Magnetically-Latched, 30-400A
	Description
	AC lighting contactors provide a safe con-
	venient means of local or remote switch-
	ing of relatively large tungsten, fluores-
	cent or mercury arc lamp loads.
	Siemens AC lighting contactors are
	designed to withstand the large initial
	inrush currents of tungsten lamp loads
	without the contacts welding. They are
	fully rated contactors and do not require
	any derating as do standard motor con-
	trol contactors. They are UL Listed and
	CSA Certified.
	Magnetic Latch Operation
	A permanent magnet is built into the con-
	tactor structure of the 30,60,100, and
	200 ampere contactors that will maintain
	the contactor in its energized state indefi-
	nitely without using control power. When
	energized, a DC current is applied that
	produces a magnetic field that reinforces
	the polarity of the permanent magnet,
	and the contactor pulls in immediately.
	The current to the coil is disconnected by
	the coil clearing interlock. In order to drop
	out the contactor it is necessary to apply
	a field through the OFF coil in the reverse
	direction to the permanent magnet. This
	momentarily cancels the magnetic attrac-
	tion and the contactor drops out.
	Cu / AI terminals are provided as stan-
	dard except on 30 ampere devices which
	are for copper wire only.
	Ballast Load:
	600 volts AC, breaking all lines. Tungsten
	Lamp Loads, Max. Volts:
	Line-to-Line, 480 AC
15
	Line-to-Neutral, 277 AC
	Combination Lighting Contactors
	It is desirable to install the branch circuit
ControlsAC	protective device and lighting contactor,
	combining switching and over-current
	protection, in one enclosure.

Type CLM Magnetically-Latched, 20A Multi-Pole

Combination lighting contactors are well suited for industrial, highway and area lighting applications, or where a lighting circuit may have to be disconnected for periodic maintenance. They may also be used for resistance heating loads.

CLM Lighting Contactors

The CLM Lighting Contactors can be used with metal halide, mercury vapor, quartz halogen, tungsten, and fluorescent lighting. They provide reliable and conve- nient lighting control in numerous applica- tions, such as industrial plants, schools, hospitals, office buildings, shopping cen- ters, airports, stadiums, etc. The CLM’s are listed under UL 508 with no derating when used open or enclosed. Optional solid-state control modules are available to allow control of the CLM lighting con- tactors directly from energy management systems, microprocessors, photoelectric cells, timers, and similar control devices. They permit programmable time schedul- ing of loads, automatic control of lighting near windows to allow the use of natural ambient lighting levels, and manual over- ride of all lighting circuits from any num- ber of local control stations or from a central location. These optional modules are integrally mounted onto the base of the lighting contactor.
