PBC-009A1F7

Contactors (Electromechanical)

A contactor is an electrically controlled switch used for switching an electrical power circuit. Contactors are often used to control motors, lighting, heating, and other electrical loads directly or for protection against overloads.

The PBC-009A1F7 is a type of contactor commonly used in industrial settings. It is designed as a three-pole contactor with a built-in overload protection relay. It is suitable for use in motor circuits where frequent switching is required and the contactor can be operated up to a rated current of 40A.

Application Field

The PBC-009A1F7 three-pole contactor is suited for a variety of industrial applications. It is especially suitable for applications that require frequent switching, such as motor circuits where the contactor can be used to switch off the motor in the event of an overload or to provide control of the starting/stopping of the motor.

The contactor can also be used for switching any number of other electrical loads, such as lighting or heating circuits. In addition, it can be used in combination with protective devices such as overload relays or circuit breakers to provide additional protection against overloads and short circuits.

Working Principle

The PBC-009A1F7 contactor utilizes an electromagnet as the actuator to open/close the contactor. When the electromagnet is energized, it generates a magnetic field which actuates the contact elements to close, thus allowing current to flow through the contacts. When the electromagnet is de-energized, the contact elements open, thus breaking the current flow. The built-in overload protection relay is designed to detect overloads and prevent prolonged current flow in the event that an overload is detected.

The contactor can be controlled manually by means of a toggle switch, or it can be controlled remotely via a control circuit. Furthermore, the contactor is provided with adjustable current limit settings, allowing the switching operation to be fine-tuned according to the application.
