Control relay for control-circuit switching
The CAD32ABD is a TeSys Deca control relay from Schneider Electric, configured with 3 normally-open and 2 normally-closed contacts. It is designed for control-circuit duty in industrial panels, switching loads per utilisation categories AC-15, AC-14, and DC-13. The 24 V DC standard coil operates within the rated voltage range, and the snap-in terminals mount directly onto a DIN rail — no tools required for installation or removal.
The AC-15 and DC-13 utilisation categories per EN/IEC 60947-5-1 define this relay for switching electromagnetic loads — contactors, solenoid valves, and small motor starters — where inrush currents can exceed steady-state. AC-14 covers switching of loads with moderate inrush, such as pilot lamps and resistive loads. The 3 NO + 2 NC contact arrangement gives you three independent make circuits and two break circuits, which suits interlocking or dual-channel safety circuits where you need both a positive-opening NC and a separate NO for feedback. The operating temperature range spans -40 to 140 °F (-40 to 60 °C), with derating permitted up to 158 °F (70 °C). The IP2X front-face protection per VDE 0106 means the relay's live parts are protected against finger contact from the front — standard for enclosed panel-mount gear. Altitude rating to 9842.52 ft (3000 m) without derating covers installations in high-altitude facilities, such as mining or mountain-based processing plants. The TH protective treatment per IEC 60068 indicates the relay is treated for tropical humid conditions — relevant for coastal or unconditioned environments.
