The Schneider Electric LC1N0901 220VAC is a compact 3-pole magnetic power contactor from the EasyPact TVS LC1N series. Rated for 9A (AC-3) motor loads up to 4kW at 400V, this contactor is engineered for standard industrial motor starting, resistive heating control, and main power switching applications. Equipped with a 220V AC operating coil and an integrated 1 NC (Normally Closed) auxiliary contact, it provides reliable switching and circuit interlocks.

Features

• Compact 3-Pole Power Architecture: Handles three-phase AC loads up to 4kW while taking up minimal space on mounting rails inside industrial control cabinets.
• Built-In 1 NC Auxiliary Contact: Features an integrated Normally Closed auxiliary contact out of the box, ideal for electrical interlocking setups (e.g., preventing two contactors in a reversing starter from closing simultaneously) or triggering fault/off status indicator lights.
• Dual DIN-Rail / Panel Mounting Base: Snaps directly onto standard 35mm DIN rails or mounts via M4 screws through the rear mounting base plate.
• Direct Thermal Overload Relay Compatibility: Designed to pair seamlessly with Schneider LREN series thermal overload relays (e.g., LREN09), plugging directly into the bottom power terminals to build a complete Direct-On-Line (DOL) motor starter assembly.

Common Applications

• Direct-On-Line (DOL) Motor Starters: Controlling small 3-phase AC induction motors (0.5HP to 5.5HP) in industrial machinery, pumps, exhaust blowers, and conveyor systems.
• Electrical Safety Interlocking: Using the 1 NC auxiliary terminal on reversing starters or star-delta transition control panels to isolate counter-running contactors.
• HVAC & Resistive Heating Switching: Switching single-phase or three-phase heating elements, ventilation fans, and industrial lighting banks up to 20A (AC-1).

Professional Installation & Usage Tips

• Distinguish Between 01 (1 NC) and 10 (1 NO) Variants: The 01 suffix in LC1N0901 indicates that the contactor includes an integrated 1 NC contact. If your control circuit requires an auxiliary contact that closes when the motor turns on (to illuminate a green "RUN" light, for instance), choose the LC1N0910 (1 NO) variant or snap an auxiliary block onto the top face.
• Verify Coil Operating Voltage (220V AC): Connect the control circuit to pins A1 and A2 using a 220V AC control signal. Applying 24V DC or 415V AC to the coil terminals will cause the contactor to fail to pull in or burn out the coil winding.
• Protect the Coil with a RC Suppressor: When controlling the coil via a delicate PLC relay output, consider adding an RC surge suppressor module across terminals A1 and A2. This suppresses high-voltage inductive spikes produced when the coil magnetic field collapses.
• Torque Terminal Screws Correctly: Tighten main power terminal screws to a torque of 1.2N⋅m to prevent loose terminal connections, high electrical resistance, and terminal overheating under full motor loads.
