Contactors (Electromechanical)

A 3100-20T6999 contactor is an electromechanical device that consists of one or more sets of movable contacts within a stationary frame that is actuated by an external control signal. Contactors are often used in industrial applications for power switching. They can be used to switch electrical equipment on and off, often in mechanically hazardous environments. Contactors are generally used when a large current must be switched or when very high voltages must be insulated. They can also be used with an auxiliary contactor to provide interlocking or protection from overload current.

Working Principle

The 3100-20T6999 contactor works on the principle of electromechanical action. When the control current flows through the coil, it creates a magnetic field, which attracts the armature. This, in turn, causes the moving contact points to close the connection and completing the circuit. Once the current flow stops, a spring on the armature, along with gravity, will cause the contact points to open. An auxiliary contactor can be used to provide additional safety or provide additional control such as switch interlocking.

Applications

The 3100-20T6999 contactor can be used in a wide variety of industrial applications including process control, motion control, motor control, and power switching. In process control applications, they are often used for controlling process valves, fans, pumps, and other process equipment. In motion control applications, they can be used for controlling the speed of motors or to provide limits to the speed of a process. In motor control applications, they are used to control the on/off switching of a motor or several motors in parallel. Contactors can also be used in power switching applications for controlling the on/off switching of circuits or machines such as conveyors.

The 3100-20T6999 contactor is suitable for motor ratings up to 25 HP at 480 Vac and 30 HP at 600 Vac. It can also be used in applications up to 600 Vac and with resistive or inductive loads of up to 40A or 85A respectively. This contactor is designed for use in hazardous environments, with an auxiliary contactor providing the necessary overload protection. It is UL listed and CSA certified and comes in a range of sizes from 4 to 10 poles.
