Contactors (Electromechanical)

A contactor is an electrically-controlled switch used for switching an electrical power circuit. The contactor is designed for high-voltage/high-current control applications such as electric motors, lighting, and heating systems. They typically consist of a fixed contact, a movable contact, an actuator, an electrical coil and a coil power source. The actuator is used to open and close the contacts, either manually or remotely, and the electrical coil creates a magnetic field to engage and release the contacts.

CC150SD24 Application Field and Working Principle

The CC150SD24 contactor is a high-performance, low-cost, short-circuit contactor designed for general-purpose applications in residential and commercial buildings. It is most commonly used to switch power circuits in air conditioners, heat pumps, refrigeration units, and other HVAC equipment. The contactor utilizes a UL recognized low-voltage, short-circuit control device that can be triggered by a single-pole switch or other low-voltage external control device. The contactor is rated for 120VAC single phase, and can be used with both the commercially available and custom-made enclosures.

The CC150SD24 contactor is made of durable phenolic material and features mechanical, electrical, and thermal overload protection. It features a 24-amp current rating at 120VAC, and has a power ON/OFF indicator. The contactor has a quick-connect terminal block that allows for ease of wiring and installation. The contactor is also UL recognized and cUL listed for safety and reliability.

The working principle of the CC150SD24 contactor is relatively simple. When the contactor is closed, the current flowing through the coils creates a magnetic field that pulls the movable contact towards the fixed contact, allowing the current to flow. When the contactor is opened, the current stops flowing, the magnetic field dissipates, and the movable contact is released. This switching of the contacts on and off helps protect electrical equipment from short circuits, power outages, and thermal overload.

In summary, the CC150SD24 contactor is an effective, reliable, and cost-effective way to switch power circuits in residential and commercial buildings. It is UL recognized and cUL listed for safety and reliability, and its quick-connect terminal block allows for ease of wiring and installation. Thanks to its mechanical, electrical, and thermal overload protection, the contactor is able to protect electrical equipment from short circuits, power outages, and thermal overload.
