Description
The Schneider Electric (Square D) LC1D50AB7 is a heavy-duty, non-reversing IEC contactor engineered for demanding electrical control applications in HVAC, commercial, and industrial systems. Rated at 50 amps across three poles with a 24VAC control coil, this contactor delivers dependable switching performance and long service life in motor and load control circuits.
Key Features
- 3-pole, non-reversing contactor configuration for straightforward load switching
- 50-amp continuous current rating for robust motor and resistive load applications
- 24VAC coil voltage for compatibility with standard low-voltage control circuits
- Everlink power connection technology with screw terminals for secure, vibration-resistant wiring
- One Normally Open (NO) and one Normally Closed (NC) auxiliary contact included for control circuit flexibility
- IEC-rated design from Schneider Electric’s trusted TeSys D series
Everlink Power Connection Technology
The Everlink screw terminal system provides a highly reliable power connection that resists loosening due to thermal cycling and mechanical vibration — a critical advantage in HVAC compressor and fan motor applications where connection integrity is paramount.
Auxiliary Contacts
The integrated 1 NO + 1 NC auxiliary contact block enables status indication, interlocking, and control circuit feedback without requiring additional add-on accessories, simplifying panel wiring and reducing installation time.
