Where are klixon discs mostly used in?
Where are klixon discs mostly used in?
Inherent protection devices for approximately 1/2 to 5 h.p. motors used in applications such as industrial motors, agricultural equipment, well and sump pumps, fans, air conditioners, refrigerators, home appliances, etc.
What is a motor Klixon?
KLIXON® Phenolic Motor Protectors are equipped with a bimetallic snap acting disc, on which the contacts are mounted, and through which the current flows. When the disc reaches the calibrated setpoint, the KLIXON® protector automatically opens and shuts down the motor, limiting the winding and shell temperature.
What is a klixon relay?
KLIXON® 4CR current type motor starting relay is a compact, high capacity relay, designed for universal application to split phase and capacitor start, single-phase motors with start-winding currents up to 25 amperes.
What is thermal overload protector?
Thermal overload relays are economic electromechanical protection devices for the main circuit. They offer reliable protection for motors in the event of overload or phase failure. The thermal overload relay can make up a compact starting solution together with contactors.
How do you protect a motor thermally?
When the motor temperature lowers, the thermal protection function automatically restarts the motor. To ensure safety, turn OFF the power supply before starting to work on the Fan. Do not use the Fan at a temperature or voltage that exceeds the operating temperature or operating voltage.
Why must the motor needs thermal overload installed?
In order to avoid unexpected breakdowns, costly repairs and subsequent losses due to motor downtime, it is important that the motor is fitted with some sort of protective device. This article will deal with built-in motor protection with thermal overload protection to avoid damage and breakdown of motor.
How does a klixon work?
The heart of the thermal circuit breaker is the KLIXON® metal disc. At a predetermined overload, the heat caused by current passing through the disc causes the disc to reverse its curvature, or snap. This snapping action separates the electrical contacts and opens the circuit.
What is a thermally protected motor?
Thermal protection is a method of fan motor protection that is activated when a motor operating at the rated voltage locks up for some reason with the power still being supplied. It uses a thermal relay inside the motor to break the circuit to the winding coil at a temperature below the level that would cause burning.
How does a klixon relay work?
The KLIXON 9660 Series motor starting relays are designated for use on single phase a-c hermetic refrigeration motors and other splitphase and capacitor – start single-phase a-c motors. When the motor is started, the relay coil is energized and lifts the armature to close the contacts.
What causes compressor thermal overload?
An overload might open due to: A lack of maintenance. If the outdoor coil gets dirty it can raise the head pressure and make the unit run hot. A defective run or start capacitor.
