COIL-C4-AC24V is a widely used industrial thermal relay. It is mainly used for starting, locking, cut off, overcurrent and overvoltage protection of motors with rated operation current of AC motor up to 52A. It is easy to install and use, and the protection effect is very good. It has become the choice of users in many fields.

The application field of COIL-C4-AC24V can be found in the electrical industry of manufacturing, water, petrochemical, refineries, oilfield, hydropower, metallurgy, power industry and other industries. Such as grain milling, paper-making, printing, plastic injection double-color, electro-hydraulic servo . The electric equipment of these industries is usually AC motors with rated operations current up to 52A. This device can be used for its starting, locking, cutting off, overcharging and overcurrent protection.

The working principle of COIL-C4-AC24V is mainly based on the K type thermoelectric power.When the current-carrying wire is twisted and heat-insulated, it will produce an induced electric current, and when the coil temperature is higher, the induced current gradually increases. When the current is large enough, the contacts are turning on. If the temperature of the surrounding environment drops, the current decreases, and the contacts turn off. Since the temperature rise generated by the rated current is relatively small, resistors with different resistances must be connected in series to ensure that the contact can be instantaneously turned on or off when the current is within the range of 0.15-1Ie.

Therefore, the working principle of COIL-C4-AC24V is suitable for use in various industrial fields. It can provide accurate and reliable protection to ensure the safe operation of motor systems. Its easy installation and use, along with its long service life, make it one of the most preferred thermal relays of today.
