Overloads are designed to protect against prolonged overcurrent of a motor which could cause the motor to overheat and burn up.Ī current sensing unit (connected in the line to the motor).Ī mechanism to break the circuit, either directly or indirectly. We could use a fused disconnect switch in place of this device. It operates to prevent large spikes of current that could be caused by a short circuit.įor more info on circuit protection, please refer to our other video.

This is a type of circuit breaker specifically designed for motor starters, that does not utilize thermal protection. Starter are commonly used in conjunction with a motor circuit protector (MCP) This can also be referred to as “Run Status” This can be normally or normally closed contact.Īllows us to control another circuit, which we can use to monitor the state of the contactor, and whether it is open or closed. Magnetic contactors use a small control current to open and close the circuit. This means that the contactor can be operated remotely, without the need for putting a person in potentially dangerous location.

(for more information on relay operations, please click on the link in the description below.)Ī magnetic contactor is operated electromechanically without manual intervention. Overload Protection protects motors from drawing too much current and overheating, from literally “burning out.”įunctions much like a relay, in that when control voltage is applied to a coil (or electromagnet) the contacts are pulled closed allowing current to pass through the contacts to the motor. Their function is to repeatedly establish and interrupt an electrical power circuit. Starters are made from two building blocks, contactors and overload protection: (however are commonly used with some form a circuit protection as well)Ĭontactors control the electric current to the motor. It is essentially a switching device.Īllows for remote operation of the motor. The primary purpose of a motor starter is to start and stop a motor which it is connected to safely.
