Telemecanique CAD32BD Contactor

Description:

The Telemecanique CAD32BD Auxiliary Contactor with LAD4TBDL Suppressor Block is used in industrial control circuits to switch auxiliary loads while protecting the 24 VDC control coil from voltage transients using a bidirectional limiting diode. Commonly installed in motor control centers, PLC control panels, automation systems, machine tools, conveyors, and process control equipment requiring reliable auxiliary switching and coil suppression. Maintenance teams and system integrators use this contactor assembly for repair, retrofit, expansion, and replacement of auxiliary control circuits in industrial electrical systems.

Applications:

The Telemecanique CAD32BD is a TeSys D auxiliary control relay equipped with a 24 VDC coil and fitted with the LAD4TBDL side-mounted suppressor module. The assembly provides dependable switching for pilot circuits, interlocking, signal distribution, and PLC interface applications while the suppressor block reduces switching transients, helping protect electronic control devices and extend relay life.
