Schneider Electric LC1D40A6B7 Iec Contactor 40A 24V

Product Description

The SCHNEIDER ELECTRIC LC1D40A6B7 is a 3-pole, non-reversible IEC contactor rated at 40 amps at 440 volts AC, controlled by a 24 volt AC coil operating at 50/60 Hz. It includes a built-in auxiliary contact block configured with one normally closed (NC) and one normally open (NO) contact. This contactor is designed for motor control and switching applications in industrial and commercial electrical panels. Licensed electricians and controls technicians install this device as part of motor starters, control circuits, and automated switching assemblies. It conforms to EN/IEC 60947-4-1 and is UL Listed, making it suitable for installations requiring recognized third-party certification.

The LC1D40A6B7 is used in industrial control panels, HVAC equipment, pump motor circuits, and commercial building automation systems where a reliable 3-pole switching device is needed. The 24 volt AC coil voltage is common in low-voltage control circuits, making this contactor compatible with a wide range of PLC outputs and transformer-fed control systems. Its non-reversible configuration suits single-direction motor loads and general-purpose load switching in both new installations and replacement applications.

Key Features

• 3-pole configuration rated at 40 amps at 440 volts AC
• 24 volt AC coil at 50/60 Hz for compatibility with standard low-voltage control circuits
• Integrated auxiliary contacts in NC and NO configuration for control feedback and interlocking
• Non-reversible action suited for single-direction motor and load switching
• UL Listed and CSA certified; meets EN/IEC 60947-4-1 and EN/IEC 60947-5-1 standards
• RoHS compliant construction

Compatibility

Designed as an OEM-style IEC contactor replacement for 3-pole, 40-amp motor control and switching applications in industrial control panels and commercial HVAC or mechanical systems.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and applicable local codes. De-energize and lock out the control panel before handling or wiring the contactor. Verify coil voltage and pole ampacity match the circuit design before energizing. Auxiliary contact terminals should be wired according to the control schematic to avoid unintended circuit behavior.
