DIN To Rail AC Contactor

The LDX2(CJX2) series AC contactor is designed for remote making and breaking of circuits and for frequent starting and control of AC motors. 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 used with an appropriate thermal overload relay, the contactor can form an electromagnetic starter for motor overload protection. The series is based on a proven LC1-D style structure and is suitable for distribution panels, industrial machinery, HVAC control cabinets, pump panels, and general automation systems where compact installation and reliable switching are required.

• Designed for remote circuit making and breaking and frequent AC 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.
• Multiple control coil voltage options are available, including 36V, 110V, 220V, and 380V AC at 50Hz.
• 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.
• Can be mounted by screws or on 35mm / 75mm DIN rail according to product size and configuration.
• Designed according to GB14048.4 and IEC947 reference requirements shown in the supplied material.

• Compact structure supports space-saving electrical cabinet design.
• Low weight and low coil power consumption reduce panel load and heat generation.
• Optional auxiliary contact blocks, delay heads, mechanical interlock mechanisms, and thermal relay accessories can be combined into derived 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.

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

• 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) contactor configuration for your panel or motor control application.
