Industrial SW182B-102 Contactor

The SW182B-102 is a dual, 24 V DC coil motor-reversing contactor assembly built from two SW181 contactors mounted on a common bracket to deliver a DPDT configuration for reversing DC motors in industrial equipment. Each half provides a SPDT contact set rated for up to 150 A continuous, enabling robust switching in medium-power drive applications. The unit is designed to operate from standard 24 V DC control circuits and is compatible with the SW181 family for easy substitution or field upgrades. A range of options supports harsh environments and custom wiring, including IP66-enclosed versions, vacuum impregnation, flying leads, coil suppression, and terminal configurations such as M4 stud terminals or M5 terminal boards. The compact two-unit assembly simplifies mounting and wiring in control panels and on equipment frames, with clear top-cover polarity markings to aid correct installation. Typical uses include motor reversing in DC drive systems where compact, reliable DPDT switching is required, such as material-handling equipment, winches, and industrial conveyors. The SW182B-102 variant confirms a 24 V DC coil and two SW181 contactors on a single bracket, enabling streamlined integration with standard control logic while preserving performance and serviceability. Note that coil and main-contact orientation can be polarity-sensitive according to the top-cover markings, so proper wiring and mounting ensure correct operation in reversing applications.
