Overview
The Square D (Schneider Electric) LC1D123BD is a TeSys Deca IEC non-reversing contactor designed for industrial motor control and resistive load switching applications. Rated 12A at AC-3 and 25A at AC-1, this 3-pole contactor handles up to 7.5HP at 460/480VAC (3-phase) with a 24VDC control coil featuring an integral suppression device. Power circuit connections are made via spring terminals, eliminating the need for tools and ensuring consistent, vibration-resistant terminations. The open-style housing supports DIN rail or panel plate mounting for flexible installation in motor control centers, control panels, and automation enclosures.
