Schneider Electric LC1K Series Contactor, 9A Operational Current, 24V Control Circuit Voltage Uc - LC1K0901B7


This contactor is a compact, three-pole switching device designed to control motors and resistive loads in industrial installations. It operates on a 24V AC control supply and is suitable for use where space is limited and frequent switching is required. The unit is intended for panel or DIN-rail installation in automation and electrical distribution panels.

Features & Benefits


• 9A operational current allows control of small motors
• 4 kW motor power rating at 380 to 415V supports medium-load drives
• 1 NC auxiliary contact provides a dedicated signalling contact
• Screw-clamp terminals permit secure connections to 0.34 to 4mm² conductors
• High impulse withstand of 8 kV improves transient tolerance
• Rated making capacity 110A AC reduces contact stress during start-up

Applications


• Suitable for controlling three-phase motors in factory automation
• Ideal for switching resistive heating elements in process panels
• Used with control systems requiring a 24V AC Coil Interface
• Can be used for Compact machine control panels with limited space
• Suitable for rail or plate mounting in distribution enclosures

What electrical environments can it handle regarding voltage and frequency?


The power circuit is rated up to 690V AC and will operate up to 400 Hz for signalling and power circuits.

How does it behave under heavy starting currents?


It offers an AC making capacity of 110A and specified short-time withstand currents, for example 90A for 1 s at 50 °C, to manage inrush events.

What are the connection options for field wiring?


Terminals accept 1.5 to 4mm² solid conductors, 0.75 to 4mm² flexible without ferrule, and smaller flexible conductors with ferrules per Terminal arrangements.

How tolerant is the device to temperature extremes and altitude?


It is specified for storage and operation between −50 °C and +80 °C and can be used at altitudes up to 2,000 m without derating.

What mechanical endurance can installers expect under nominal load?


Mechanical life is rated at 10 M cycles and electrical endurance at 1.3 M cycles for 9A AC-3 switching at up to 440 V.
