    Product Description

    WEG CWM40-10-30V37 Contactor | 40A, 3-Pole, 30 HP | 277V AC Coil (V37)

    Includes 1 N.O. Auxiliary Contact | Direct Replacement for GE CL45A310M

    The WEG CWM40-10-30V37 is a durable, 3-pole IEC contactor designed for motor control in applications where 277V AC control voltage is required (V37 code). This unit is rated for 40 AMPS (AC-3 duty) and handles motor loads up to 30 HP at 460V (3-phase) or 15 HP at 230V.

    Ideal for commercial and industrial use, this contactor comes standard with one Normally Open (1 N.O.) front-mounted auxiliary contact (BCXMF10) for control circuit signaling. It is the authorized, dimensionally, and electrically compatible replacement for the obsolete GE CL45A310M contactor, ensuring a straightforward and reliable system upgrade.
