WEG CWCA0-40-00V18 is a four-pole IEC control relay with four normally open (4NO) contacts and a 120VAC coil. Part of the CWCA0 series, this compact relay is designed for industrial control circuits, providing reliable switching for auxiliary functions in motor starters, automation panels, and machine controls. It features a plug-in design for easy installation and maintenance, meeting international IEC standards for safety and performance.

Developed for different applications on control circuits. They can be directly mounted on DIN rail EN 50.002 or tightened with screws, and offer compact size and a full line of accessories.

The auxiliary minicontactors and contactors of the CAWB, CWCA0 and CAW04 line are designed for a variety of applications in control circuits.

• Directly mounted on DIN rail 35 mm or tightened with screws;
• Protected against foreign bodies and touch;
• High reliability of the contacts (17 V - 5 mA);
• CWCA0 compact contactor with low-consumption DC coils, enabling direct connection to PLCs;
• Same dimensions (AC or DC coil) for the CWCA0 models;
• The CWCA0 compact contactors meet the requirements of IEC 60947-5-1 regarding contacts mechanically linked.
