Phoenix Contact CBL-SC-24UC/31/63A 24 V AC/DC Installation Contactor 63 A 3NO + 1NC

The Phoenix Contact CBL-SC-24UC/31/63A is a rugged installation contactor suited for industrial control panels, automation systems, and load switching applications. Designed for 24 V AC/DC coil operation, this electromechanical contactor delivers reliable switching with a rated continuous current of 63 A and a contact layout of three normally open (NO) contacts and one normally closed (NC) contact — perfect for controlling motors, heaters, pumps, and lighting loads.

Built for durability and performance, this contactor features a monostable drive, a wide voltage range (20.4–26.4 V AC/DC), and a robust insulation system rated up to 440 V and 4 kV surge voltage. It supports high rated operating currents including 63 A at 24 V DC, and up to 40 kW power switching at 400 V AC under typical AC-1 load conditions.

Mounting is quick and secure on standard 35 mm DIN rail, with screw connection terminals for both coil and contacts. Designed to withstand vibration, shock, and ambient operation between -15 °C and +35 °C, this contactor is ideal for industrial automation, machinery control cabinets, and HVAC systems.
