Woodworking Contactors

1.High-efficiency large current control capability

High load switching：Support frequent switching of up to 800 ampere current, suitable for starting and stopping management of high-power equipment such as motors and welding machines, mechanical structure can withstand thousands of operations per hour, far beyond the limit of ordinary switches.

Arc extinguishing safety design：Equipped with a grid or vacuum arc extinguishing device, it can safely cut off 386 volts of alternating current circuit, significantly reducing arc hazards.

2.Intelligent control and safety protection

Remote and automated operation: Control the high-voltage main circuit remotely through low-voltage signals (buttons, PLCs, or sensors), achieving intelligent start- of production equipment or centralized management of building air conditioning.

Multiple protection mechanisms:

Low voltage release: Automatically cut off power when the voltage drops to 60%-75% of the rated value to prevent equipment damage from undervol.

Zero voltage protection: Avoid accidental restart of equipment after abnormal power outage of the power grid.

Interlinked protection: In combination with fuses, thermal relays, it provides overload, short circuit and leakage protection.

3.Economy and functional extensibility

Long life low cost: The cost per operation is more than 65% lower than traditional relays, and the maintenance cycle is extended threefold, significantly increasing service life of the equipment.

Flexible logic control: Self-locking and interlocking logic can be realized through normally open/normally closed auxiliary contacts (such as forward and reverse control the motor), and multi-point operation and sectional control are supported.

4.Broad applicability and scene adaptation

1）Industrial field: motor start and stop, forward and reverse control, and automated production line equipment management.

2）New energy system: photovoltaic power switching and storage device on-off management.

3）Home scene: remote control and energy-saving management of large power appliances such as air conditioners and water heaters.

4）Special environmental adaptability: such as the optimization of heat-resistant materials for Hongfa contactors to ensure stable operation in high-temperature environments.

The application scope of contactors covers industry, architecture, household appliances and emerging technology fields, realizing the safe control and automated management of large current loads

Industrial automation: control the start and stop, forward and reverse rotation of the motor and the automation of production line equipment, to improve the efficiency and reliability of the line.

Power system: used for switch power supply, generator opening and closing operation and load switching of distribution line, cooperate with protection device to prevent fault.

Building electrical: manage central air conditioning units, large lighting systems and other equipment to achieve centralized control of building energy.

Home appliances: remote control of air conditioners, water heaters and other high-power appliances to improve safety and energy conservation.

New energy field: Ensure efficient energy conversion in photovoltaic power switching and energy storage equipment management.

Special scenarios: high reliability power control in aerospace field and management of large current equipment such as welding machines and capacitor banks

The core function of a general switch (such as a circuit breaker) is circuit protection (overcurrent/short circuit tripping), while a contactor specializes automated control. The two are often used together to achieve both safety and efficiency.
