With the widespread use of electronic devices, thermal protection, and heat dissipation problems have attracted attention. Especially in equipment like motors, fans, power supplies, etc., overheating can lead to failure or even burnout of components that are essential for operation. Fortunately, thermal protector products exist, and they can prevent this outcome effectively.
From motors and fans to transformers, coils, and more, a thermal protector is effective for a wide range of equipment. Some of the top applicable equipment include the following:
A motor can overheat due to various reasons, e.g., something locking the motor shaft, the bearing seizing up, etc. A thermal protector automatically shuts down the motor to prevent overheating and resets once it cools down to a safe operating temperature.
- Water Pumps
Water pumps also require thermal protection for safe operation. Too many amps can overheat the water pump and cause damage. A thermal protector for the motor prevents this outcome by shutting off the water pump before it overheats.
Fans can overheat due to increased voltage and other factors. A thermal protection switch helps prevent damage to the winding by ensuring it functions within a safe operating temperature.
- Power Supply & Power Pack
Power supplies and power packs generate heat, and hence, they require sufficient active or passive cooling. If there is a problem with their cooling or airflow, the temperature of the unit can increase greatly, leading to malfunction or shortening the unit’s life. The solution is a thermal protection switch that monitors the temperature and prevents overheating.
Why is Thermal Protector Switch Important for Equipment?
Thermal protector plays an important role in the protection of electrical devices. It is designed to prevent overheating that can cause severe damage to the electrical equipment. It achieves this by performing these two primary functions:
- Monitor the Temperature of the Equipment
The thermal protector has one or more temperature monitoring sensors that measure the temperature of various components of an electrical appliance. The purpose is to take immediate action when the temperature of any of these components rises above the safety threshold.
- Automatically Shut Off the Electrical Circuit
When the temperature of the unit or any of its key components exceeds a safe level, the thermal protector for the motor automatically shuts off the electrical circuit to prevent damage. The thermal protection switch resets when the unit’s temperature falls to a safe level.
