Motor thermal protectors are a necessary safety device that is now required in many commercial and industrial applications. This blog will discuss five important things you need to know about this important device and what you should do if you have one installed in your facility.
Information of motor thermal protector
A motor thermal protector is a device that is used to protect motors from overheating. It is typically installed in the winding of the motor and monitors the temperature of the winding. If the temperature of the winding exceeds a certain threshold, the thermal protector will open and disconnect the power to the motor. This will prevent the motor from overheating and being damaged.
Why You Need a Motor Thermal Protector?
There are many reasons why you might need a motor thermal protector. If your motor overheats, it can cause serious damage to the winding insulation and other components. A thermal protector will shut off the power to the motor before it gets too hot, preventing this damage from occurring.
Another reason to use a thermal protector is if your motor is exposed to excessive moisture. This can happen if the motor is located in an environment where there is high humidity or if it is frequently exposed to rain or snow. The moisture can cause the insulation on the windings to break down, leading to shorts and eventually failure of the motor. A thermal protector will shut off the power to the motor before the insulation gets too wet, preventing this from happening.
Finally, you may need a thermal protector if your motor is subject to wide temperature swings. This can happen if the motor is located in an area where there are drastic changes in temperature, such as near a furnace or in a garage that isn’t well insulated. The changing temperatures can cause the windings to expand and contract, leading to fatigue and eventual failure. A thermal protector will shut off the power to the motor before the windings get too hot or too cold, preventing this from happening.
Types of thermal protectors
There are three main types of thermal protectors: fusible links, bimetallic strips, and thermal cutoffs. Fusible links are the most common type of thermal protector. They are made of a metal alloy that melts at a specific temperature, which causes the circuit to break and the motor to shut off. Bimetallic strips are made of two different metals that expand at different rates when heated. This causes the strip to bend, which breaks the circuit and shuts off the motor. Thermal cutoffs are devices that contain a liquid or gas that expands when heated and breaks the circuit.
