Schneider Electric (Square D) LC1D40AF7 3-Pole 40A Non-Reversing Contactor, 110VAC Coil

Description

The Schneider Electric (Square D) LC1D40AF7 is a heavy-duty, non-reversing IEC contactor engineered for dependable motor and load control in commercial and industrial HVAC applications. Designed to handle demanding electrical environments, this contactor delivers consistent switching performance and long service life.

Product Overview

The LC1D40AF7 features a 110VAC coil that energizes a robust 3-pole switching configuration rated at 40 amps, making it well-suited for controlling compressors, fan motors, pumps, and other HVAC equipment. Its Everlink power connection technology ensures a secure, vibration-resistant terminal interface that maintains contact integrity over time — reducing the risk of loose connections and associated failures.

Key Features

• 3-pole, non-reversing contactor configuration
• 40-amp continuous current rating
• 110VAC control coil (AF7 coil designation)
• Everlink power connection technology for secure, vibration-resistant screw terminal connections
• One Normally Open (NO) auxiliary contact included
• One Normally Closed (NC) auxiliary contact included
• Screw terminal power connections for easy field wiring
• IEC-style contactor design for compact panel integration

Auxiliary Contacts

The integrated auxiliary contact block provides both a Normally Open (NO) and a Normally Closed (NC) contact, enabling flexible control circuit interlocking, status indication, and safety logic without requiring additional add-on blocks.

Everlink Power Connection Technology

Everlink terminals use a captive screw and spring-loaded pressure plate to maintain consistent clamping force on conductors, even under thermal cycling and mechanical vibration. This technology reduces maintenance intervals and improves long-term connection reliability in demanding HVAC environments.

Typical Applications

• HVAC compressor motor control
• Condenser and evaporator fan motor switching
• Pump and blower motor control panels
• Commercial rooftop unit electrical panels
• Industrial motor control centers (MCCs)
• Building automation and energy management systems
