Schneider Electric (Square D) LC1D50G7 Contactor

The Schneider Electric (Square D) LC1D50G7 is a high-performance 3-pole non-reversing contactor engineered for demanding motor control and resistive load applications. As part of the TeSys Deca series, this industrial-grade component is rated for 50 Amps (AC-3) and supports motor loads up to 40 HP at 480V. The integrated 120Vac coil (50/60 Hz) ensures consistent actuation, while the standard 1NO and 1NC auxiliary contacts simplify control circuit integration. Professionals often identify this unit by its legacy cross-reference RADLC1D50G7.

Built for reliability in harsh HVACR environments, the LC1D50G7 contactor features secure screw clamp terminals that maintain high-torque connections even under vibration. Its IEC rated design is DIN rail and plate mountable, providing flexibility for panel builders and technicians. With high-fault SCCR ratings up to 100kA when fused correctly, this Square D contactor delivers the robust electrical protection required for industrial machinery and commercial climate control systems.

Key Benefits:

• Enhanced 50A inductive rating for superior 3-phase motor management.
• Built-in 1NO and 1NC contacts eliminate the need for extra auxiliary blocks.
• Universal 120V coil compatibility for standard control transformer secondary circuits.
• Proven TeSys Deca architecture ensures long mechanical and electrical lifecycle.
• Terminal covers and IP20-rated touch-safe design improve safety during maintenance.

Common Questions:

Can I use the LC1D50G7 for single-phase applications?
Yes, this 3-pole contactor is rated for single-phase loads, typically handling up to 3 HP at 115V or 7.5 HP at 230V, though it is optimized for 3-phase machinery.

What is the maximum operating temperature for this unit?
The LC1D50G7 is designed to operate reliably in ambient environments ranging from -5°C to 60°C without derating performance.

Is this contactor compatible with thermal overload relays?
Absolutely. This unit is designed for direct mounting with Schneider Electric LRD33 or LR3D series thermal overload relays to provide complete motor protection.
