WEG CWB12 Contactors

Technical description

WEG CWB12 series contactors are compact, with 45 mm width available up to 38 A (18.5 kW at 380 V AC-3 three-phase), 54 mm width available from 40 to 80 A (37 kW at 380 V AC-3 three-phase), and 72 mm width available from 95 to 125 A (55 kW at 380 V AC-3 three-phase), CWB contactors lead to an overall reduction in the size of electrical panels compared to traditional contactor solutions with the same specification.

Built-in 1NA + 1NF Auxiliary Contacts
They meet most applications without the need for additional contacts, allowing a reduction in stock items. They have self-cleaning characteristics where, through sliding contacts, they provide high reliability in low voltage and current maneuvers (17 V / 5 mA). Easy front access even with power cables connected.

Assembly Efficiency
Mounting via 35 mm DIN rail (EN 50022-35) allows for faster and more efficient assembly. Its oblong screw fixing base is fully compatible with most existing contactors, allowing for easy replacement with the CWB line. It has a place for passing control cables, enabling the use of a single channel, saving space and assembly time.
