Description
HVAC CONTACTORS are essential electrical switching devices used in air-conditioning, refrigeration, heating, and industrial control systems. They are designed to handle high electrical loads, control compressor motors, manage fan operations, and provide safe switching for high-voltage components. A reliable contactor ensures smooth equipment performance, prevents electrical failures, and extends the life of the entire HVAC system.
These contactors are available in both 2-pole and 3-pole configurations with coil voltage options of 24V and 220V, making them compatible with a wide range of HVAC units and control systems.
Available Models
- Contactor 2 Pole – 24V
- Contactor 2 Pole – 220V
- Contactor 3 Pole – 24V
- Contactor 3 Pole – 220V
Details & Usage
2-pole contactors are commonly used in single-phase air conditioners, small cooling units, and residential AC systems where two power lines need to be switched. 3-pole contactors are ideal for three-phase equipment such as large compressors, industrial chillers, cold rooms, heat pumps, and commercial refrigeration machinery.
The 24V coil versions are typically used with low-voltage control circuits operated by thermostats, PCB control boards, or control relays. The 220V coil versions are designed for systems where the control signal is taken directly from mains voltage, which is common in commercial and industrial HVAC applications.
