Starter Accessories & Equipment

Contactor auxiliary contact blocks are used in a relay logic circuit typically switching 120 Volt AC power, instead of the motor voltage. A contactor is a relay that is used to switch a large amount of electrical power through its contacts. Contactors usually have multiple contacts that are normally-open, so that power to the load is shut off when the coil is de-energized. The most common industrial use for contactors is the control of electric motors. 

Starter replacement coils are part of contactor used in the control of electric motors. When a contactor is closed, current flows to the coil (electromagnet) creating a magnetic coupling between contacts allowing current to flow to the motor. When de-energized, a spring causes the contacts to separate and stop the flow of power to the motor.

Starter thermal elements are part of thermal overload relays that indirectly measure motor heating by monitoring the amount of electrical current being delivered to the motor. Current flowing to the motor also flows through thermal overload relays by wiring them in series. When the current reaches or exceeds a preset limit, the relay activates a mechanism that opens one or more contacts to interrupt the current flow to the motor.

Starter disconnects and breakers are devices that work together to interrupt the flow of electricity along a circuit when an overcurrent occurs. Circuit breakers are designed to remove the current from a circuit when it exceeds a preset limit to prevent damage to connected devices. It does this automatically and immediately. A disconnect switch controls the flow of current to a circuit. It manually starts and stops power from an electrical supply by opening or closing an air insulation gap between two conduction points.
