Thermally protected motor switch.

Hubbell circuit lock nema 1 enclosures with switch are suitable for use in indoor environments to manually control single or three phase ac motors. Electric motor thermal overload switch location. Electric motor thermal overload switch location. Klixon and thermik are examples of thermal switch these devices are also called pto protection thermique à ouverture.

Built for commercial and industrial installations up to 60 amps leviton offers a line of industrial grade ac single phase and three phase manual motor controllers with a continuous current rating at all voltages up to 600v. Combine a switch and a thermal overload element to build a starter that can handle high current rated motors. Assemble your own motor starter by combining a switch and a thermal overload element. The thermal protection is present to turn the motor off when excessive heat is generated within the motor circuitry.

These motor switches come mounted in an enclosure for protection against dust or damage from solid objects. Nema 4 and 12 rated switches are protected from washdowns and oil coolant dripping. For instance if on the nameplates is a marking. This safety feature halts the temperature climb before it can burn up the motor.

Thermal overload elements shut motors off if current exceeds the full load current rating. Provide on off control for a motor and protect it from overloads. Please specify the full load current rating of your motor. That means that there s a switch which protects the motor of overheating.

Powerswitch manual motor controllers heavy duty horsepower rated switches capable of providing manual on off control to higher motor loads than standard toggle switches. Thermal protection built into the windings. Rated nema 4x these enclosed starters are protected from corrosion and washdowns. Bear in mind that the resulting switch acts like an on off toggle not a push button start push button stop like a normal 3 phase starter.

The thermal protector consists of one or more heat sensing elements built into the motor or motor compressor plus an external control device. They are commonly used on industrial equipment such as conveyor systems and industrial fans.
