Thermally Protected Motor Switch

Provide on off control for a motor and protect it from overloads.

Thermally protected motor switch. These motor switches come mounted in an enclosure for protection against dust or damage from solid objects. For instance if on the nameplates is a marking. Rated nema 4x these enclosed starters are protected from corrosion and washdowns. Assemble your own motor starter by combining a switch and a thermal overload element.

Thermal overload elements shut motors off if current exceeds the full load current rating. F it means that the motor is protected up to 155 c. You could also add triple pole double throw tpdt switch or use a triple pole triple throw to begin with to be able to reverse the motor direction in addition to turning it on or off. Electric motor thermal overload switch location.

Hubbell circuit lock nema 1 enclosures with switch are suitable for use in indoor environments to manually control single or three phase ac motors. Thermal protection to be connected in series with the winding or to a control circuit in the motor. They are commonly used on industrial equipment such as conveyor systems and industrial fans. 17am d 65c 250v 10a motor thermal protector thermal cut out switch self hold 17am d manual reset motor thermal protection for garden tooling 17am d ptc 250v 8a 125v 10a motor thermal protector 50 170 ul kc vde approved.

Electric motor thermal overload switch location. Thermal protection built into the windings. That means that there s a switch which protects the motor of overheating. Combine a switch and a thermal overload element to build a starter that can handle high current rated motors.

Klixon and thermik are examples of thermal switch these devices are also called pto protection thermique à ouverture. Nema 4 and 12 rated switches are protected from washdowns and oil coolant dripping. The thermal protection is present to turn the motor off when excessive heat is generated within the motor circuitry. Please specify the full load current rating of your motor.

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.
