An electrically controlled switch called a power contactor is used to switch a power circuit. A circuit that is often considerably weaker than the switched circuit, such as a 24 volt coil electromagnet controlling a 240 volt motor switch, controls the contactor.

An electrical motor's speed is managed by an AC drive, which can be used to improving process control lessen mechanical stress on motor control applications, generate energy more efficiently, and improve the performance of a variety of applications that use electric motors.

A moulded case circuit breaker (MCCB) is a type of electrical protection device that is used to protect the electrical circuit from excessive current, which can cause overload or short circuit.

A device for repeatedly establishing and interrupting an electric power circuit under normal conditions .A contactor is a special type of relay used for switching an electrical circuit on or off. They are most commonly used with electric motors and lighting applications.

An overload relay, also referred to as a relay switch, is a device that opens the circuit in the event of an electrical, thermal or power overload. When mounted with a contactor they create a motor starter. Overload relays are normally closed, meaning they only open if they experience an overload.

FASD starters are basic electrical starters with contactor and relay combination for ON-OFF operation and overload protection of the pump-sets.
