Circuit Breakers are widely used in many applications to protect electrical systems from overload and short-circuit damages. One such device is the 412-K14-N2-7.5A circuit breaker, which is used in many different applications and industries. Its working principle is based on its ability to cut off the flow of electricity when an overload or short circuit occurs.

Overview

The 412-K14-N2-7.5A is a single-pole, thermal-magnetic circuit breaker intended for applications with a rated current of 7.5A. It is composed of a Reset Button and a Contact Block, along with a Thermal Magnetic Release. The Reset Button is used to manual reset the circuit breaker after an overload or short-circuit condition has been cleared. The Contact Block is the part of the breaker which makes contact with the line wire, allowing current to flow. The Thermal Magnetic Release is what detects an overload or short-circuit condition and trips the breaker off automatically.

Application Fields

The 412-K14-N2-7.5A is used for low-amperage overload or short-circuit protection in a variety of applications, such as electrical control systems, digital circuits, lighting systems, automotive circuits, and other smaller applications. In the industrial and manufacturing industries, it is used for motor circuits, pumps and other electrical systems.

Working Principle

The 412-K14-N2-7.5A works by detecting an overload or short-circuit condition and trips the breaker off automatically. When a current is applied to the contacts connecting to the line wire, the Contact Block will close and allow electric current to flow. The Thermal Magnetic Release then detects the current passing through and compares it to the set threshold, and if the current exceeds the set threshold, then the release will trip and cut off the electric flow.

In order to reset the breaker, then the Reset Button is used. In order to avoid reapplication of unintentional short-circuit or overload conditions, the breaker must first be manually reset before it will allow current to pass again. This ensures that any further overload or short-circuit conditions will not cause further damage to the electrical system.

Conclusion

The 412-K14-N2-7.5A is a thermal-magnetic circuit breaker used mainly in applications that require low-amperage overload or short-circuit protection. As it is not intended for applications with a high current, it can protect the electrical system from any further damage that would be caused by an overload or short-circuit. Its device resets using a Reset Button, and it can be used in a variety of applications, such as electrical control systems, digital circuits, lighting systems, automotive circuits, and other smaller applications.
