Schneider Electric LC2D18B7 Iec Reversible Contactor 18A 24V

Product Description

The SCHNEIDER ELECTRIC LC2D18B7 is a 3-pole IEC reversible contactor designed for motor control and switching applications in industrial and commercial electrical systems. Rated at 18 amps at 440 volts AC, it operates on a 24 volt AC coil at 50/60 Hz, making it compatible with standard low-voltage control circuits. The reversible configuration allows forward and reverse motor operation from a single contactor assembly. It includes both a normally closed (NC) and normally open (NO) auxiliary contact configuration, supporting interlocking and status signaling without additional add-on blocks. Licensed electricians and industrial controls technicians are the primary installers of this device.

This contactor is suited for reversible motor starter applications in light industrial, commercial HVAC, and process control panels. The 24 volt AC coil voltage is a common choice for control transformer-fed panels operating at 50 or 60 Hz. The included auxiliary contacts support standard interlocking schemes required in reversing motor control circuits. It is packaged individually and ships as a single unit.

Compatibility

Designed as an OEM-style replacement or new-installation IEC contactor for reversible motor starter applications in control panels meeting IEC and UL 508 panel standards.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. De-energize and lock out the control panel completely before mounting or wiring the contactor. Verify coil voltage matches the control circuit supply before energizing. In reversing starter configurations, confirm mechanical and electrical interlocking is properly configured before commissioning to prevent phase-to-phase faults.
