220V 2-pole 25A AC day/night contactor on DIN rail for lighting, heating and ventilation

1. [Principle]: The AC contactor uses electromagnetic, pneumatic, or hydraulic principles to switch the main circuit on and off via the control circuit, thus achieving the goal of low-current control for high-current equipment. 2. [Application]: The manual/automatic AC contactor can be used for remote control, lighting, heating, ventilation, roller shutters, public hot water, mechanical ventilation systems, and low-inductance micro-inductive loads. 3. [Design]: The AC contactor adopts a unique four-position switch design, supports manual control and automatic operating parameters, and the reliable electromagnetic system ensures fast response and switching. 4. [Installation]: The domestic AC contactor adopts a standard 35mm rail design and can be quickly installed in the distribution box or industrial circuit. 5. [Features]: The size of the rail contactor module is reduced by 70%, and the operating noise is less than 15dB, which is better than the performance of traditional contactors.
