WEG CWM40-00-30V18L : 3-Pole Lighting Contactor, Normally Open (3 NO), 120 VAC 60 Hz / 110 VAC 50 Hz Coil, 60A AC-1, 40A AC-3
The WEG CWM40-00-30V18L is a 3-pole CWM40 frame contactor with three normally open main contacts, no auxiliary contacts and a 120 V 60 Hz / 110 V 50 Hz coil. It is rated 60 A AC-1 at 690 V or less and 40 A AC-3 at 440 V or less. The three poles switch together and open when the coil is de-energized.
Best for: three-phase lighting and general purpose loads up to 60 A, or motors up to 30 HP at 460 V, switched from a 120 VAC control circuit.
Key Features
Three normally open poles
Switches a three-phase load, or three single-phase circuits, from one control signal. Contacts open when the coil drops out.
60 A AC-1, 40 A AC-3
Rated 60 A for resistive and general purpose loads at 55 °C and 40 A for motor duty at 440 V or less, with 33 A AC-5b (indicative) for incandescent lamp loads.
120 V 60 Hz / 110 V 50 Hz coil
Pick-up at 0.5 to 0.76 x Uc and drop-out at 0.3 to 0.65 x Uc, with 98 VA inrush.
UL motor ratings
15 HP at 230 V, 30 HP at 460 V and 25 HP at 575 V three-phase, and 3 HP at 115 V single-phase.
Panel or DIN rail mounting
Mounts on a 35 mm DIN rail or by screws to a panel.

Frequently Asked Questions
What is the coil voltage of the WEG CWM40-00-30V18L?
The V18 coil is rated 120 V at 60 Hz and 110 V at 50 Hz. On a 60 Hz control circuit in North America, use it as a 120 VAC coil.
What current is the CWM40-00-30V18L rated for?
60 A under AC-1 (resistive and general purpose loads, 55 °C, 690 V or less), 40 A under AC-3 for motors at 440 V or less (32 A at 500 V), and 33 A under AC-5b for incandescent lamps as an indicative value. For ballast and LED driver circuits, call Team Zot at 855-825-2811 and we will help size the contactor.
What is the difference between the AC-1 and AC-3 ratings?
They are IEC utilization categories for different loads. AC-1 covers resistive and slightly inductive loads such as heaters and general purpose circuits, so it is the higher figure: 60 A. AC-3 covers starting and stopping squirrel-cage motors, where inrush is much higher, so the rating is lower: 40 A at 440 V or less. Size the contactor to the category that matches your load.
What size motor can the CWM40-00-30V18L switch?
UL ratings are 10 HP at 200 V, 15 HP at 230 V, 30 HP at 460 V and 25 HP at 575 V three-phase, and 3 HP at 115 V single-phase.
Is the CWM40-00-30V18L normally open or normally closed?
Normally open. All three main contacts are open with the coil de-energized and close when the coil is energized. It has no auxiliary contacts.
How does the CWM40-00-30V18L mount?
On a 35 mm DIN rail or by screws to a panel. It weighs 0.650 kg (1.43 lb).
