CONTACTOR - THERMAL OVERLOAD RELAY SHIHLIN

In the electrical industry, protective and control devices are essential elements that help ensure the stability and safety of the system. The contactor and thermal overload relay are two of the most important devices in electrical systems, especially in motor applications. In this article, we will explore the contactor and thermal relay, the quality of Shihlin's contactor and thermal relay products, and introduce Promax Electric Co., Ltd. – the exclusive distributor of Shihlin in Vietnam.

What is the contactor?

Contactor are electrical devices used to control large electrical equipment such as motors, pumps, fans, or other industrial loads. They have the ability to open and close electrical circuits remotely using a control signal, allowing the system to operate easily without the need for direct handling of high-power circuits. Although their primary function is to open and close circuits, contactor also play an important role in protecting equipment from issues such as overloads or short circuits.

Contactor are widely used in industrial electrical systems because they can withstand high currents, operate stably, and are easy to maintain. This device works based on the principle of magnetic fields to pull contacts together, allowing current to flow through the circuit. Some common applications of contactors include starting and stopping motors, controlling lighting systems, or being used in automated electrical systems.

What is the Thermal overload relay?

Thermal overload relay are important protective devices in industrial electrical circuits, especially in motor control systems. Thermal overload relay are designed to protect motors from overload conditions, ensuring that the motor does not get damaged due to overheating. When the current through the motor exceeds the safe level for an extended period, the thermal relay is activated and disconnects the circuit, stopping the motor and preventing serious damage.

Thermal overload relay operate based on the principle of temperature change, typically using bimetallic strips. When the current through the motor increases and raises the temperature of the relay, the bimetallic strips bend, causing the circuit to disconnect and protecting the motor from overload damage.

Thermal overload relay are combined with contactors in motor control applications to protect the motor from overloads or high-temperature issues. This helps minimize maintenance and repair costs and extends the motor's lifespan.
