3 To Pole AC Contactor

The LDX2(CJX2) series three-pole AC contactor is designed for remote making and breaking of circuits, frequent starting of AC motors, and reliable control in electrical panels. It is suitable for AC 50Hz or 60Hz applications with rated operating voltage up to 660V, and the AC-3 motor-control current range covers compact cabinet applications up to 95A at 380V.

When matched with a suitable thermal overload relay, the contactor can form an electromagnetic starter to support motor overload protection. The product family is based on a proven LC1-D style structure, offering compact size, low power consumption, flexible auxiliary contact options, and practical mounting choices for motor control cabinets and automation systems.

• Three-pole main contact structure for AC motor control and power switching.
• Designed for remote circuit making, breaking, and frequent motor starting.
• Rated for AC 50/60Hz systems with insulation voltage up to 660V.
• AC-3 motor-control rated current range covers 9A to 95A at 380V.
• Coil voltage options include 36V, 110V, 220V, and 380V AC at 50Hz, with other configurations available by requirement.
• Optional normally open and normally closed auxiliary contacts support control circuit expansion.
• Compact body, light weight, low coil power consumption, and long service life support dense cabinet layouts.
• Supports screw mounting, 35mm rail installation, and selected 75mm rail installation depending on product size.

• Three main poles are suitable for standard three-phase motor control circuits.
• Optional auxiliary contact blocks, delay heads, mechanical interlock mechanisms, and thermal relay accessories can be combined into derived control products.
• Models below 32A usually provide one pair of auxiliary contacts; 40A and above can provide auxiliary contact combinations according to configuration.
• Except for screw mounting, the series supports 35mm rail installation and selected larger sizes can also use 75mm rail installation.
• Control coil terminal markings A1 and A2 help simplify wiring identification.
• Compact structure supports space-saving design in distribution cabinets and machine control panels.

This three-pole contactor series is suited to control systems that need reliable AC motor switching, compact installation, and flexible auxiliary control options.

• Three-phase motor control cabinets and electromagnetic starters
• Pump, fan, compressor, and conveyor control circuits
• HVAC and building automation panels
• Industrial machinery control systems
• Distribution boards and automation cabinets
• Frequent start-stop motor applications
• Control panels using contactor plus overload relay combinations

• Before installation, verify that coil voltage, rated current, and operating frequency match the power supply and load.
• Tighten terminal screws correctly and check the wiring before energizing the main contacts.
• Avoid dropping washers, wire ends, and other foreign objects into the contactor during installation.
• If abnormal noise occurs during operation, clean the pole surface or check for foreign matter.
• Regularly inspect product parts during use; replace damaged components promptly.
• When ordering, specify contactor model, coil rated voltage and frequency, quantity, and whether auxiliary contacts or standard rail accessories are required.

Send us your rated current, coil voltage, control frequency, auxiliary contact requirement, mounting method, and project quantity, and we will recommend the proper LDX2(CJX2) three-pole contactor configuration for your panel or motor control application.
