Contactor Schneider Electric LC1D, 3-pole, rated insulation voltage 600 V, Uimp 6 kV, 45×92×85 mm

Schneider Electric LC1D is a three-pole electromagnetic contactor engineered for switching and control of AC circuits in industrial and commercial installations. The device provides reliable make-and-break operation for motors, lighting and general power loads. With a rated insulation voltage of 600 V and an impulse withstand voltage of 6 kV, this compact contactor measures 45 mm wide, 92 mm deep and 85 mm high, making it suitable for installation in distribution boards and control panels with limited space.

Advantages

The LC1D contactor combines a compact footprint with robust electrical characteristics, offering stable switching performance and a high rated insulation level for safety in harsh electrical environments. Its three-pole construction supports three-phase load switching while the standardized dimensions simplify panel mounting and replacement of similar modular contactors. The product is compatible with typical auxiliary and control circuit accessories used in motor starters and lighting control systems.

Suitable for

• Three-phase motor starters and soft starter bypass switching
• Switching and control of industrial and commercial lighting circuits
• General-purpose switching of resistive and inductive loads within rated voltages
• Control panels and distribution boards with space constraints

Key specifications

• Poles: 3-pole configuration for three-phase circuits
• Rated insulation voltage: 600 V suitable for typical industrial AC systems
• Rated impulse withstand voltage (Uimp): 6 kV for transient overvoltage resistance
• Dimensions (W×D×H): 45 × 92 × 85 mm for compact panel installation
• Electromechanical operation: electromagnetic contactor suitable for AC switching tasks

How to use

Mount the contactor on a DIN rail or panel according to local electrical codes and the enclosure layout, ensuring adequate clearance for ventilation and wiring. Connect the three input and three output power conductors to the main poles and wire the control coil to the appropriate control circuit voltage. Verify that the system voltage and anticipated transient levels do not exceed the contactor's rated insulation and impulse withstand voltages. Perform functional checks by energizing the coil and observing correct make-and-break operation before placing the contactor into continuous service.

Recommendations

Use the contactor within its rated voltage limits and pair it with suitable overload protection and auxiliary devices when used for motor control. Periodically inspect contactor contacts and terminal connections for wear and tightness in accordance with maintenance schedules to ensure long-term reliable operation.
