Overview

Fuseholders are components used to protect electrical circuits from overloading. They contain fuses or circuit breakers that are placed in the circuit as a safety device to prevent an electrical overload that can cause permanent damage to the electrical system. 03420828HXL is one such type of fuseholder. This article will discuss the application field and working principle of 03420828HXL.

Application Field

03420828HXL is a versatile medium-sized fuseholder designed for use in industrial and commercial applications. It is applicable for 600Vac, including controls, power distribution, and equipment. The 03420828HXL is designed for direct-in-line operation as well as dead front applications and is also suitable for hazardous locations. This fuseholder can also be used for easy-to-install fused disconnect switches with amperage ratings from 10A to 60A and has a maximum watt density of 25W/in².

Installation

03420828HXL features a self-contained, 2-piece design with a removable cover and a secure, spring-loaded contact to ensure quick, safe, and accurate installation. The terminal clamp screws quickly secure wires up to 500 MCM in size and provide excellent reliability. The 1/4-filled enclosure and gasket-sealed cover also provide added protection from the environment.

Working Principle

The 03420828HXL is a thermal magnetic circuit breaker type fused disconnect switch. This means that it uses two processes to protect the circuit. The first process is a thermal protection mechanism which monitors the circuit temperature and in the event of an abnormal rise in temperature, will activate and open the circuitbreaker. This is the first line of protection and it is intended to protect the circuit from overloads. The second process is a magnetic protection mechanism which monitors the current flow in the circuit and is designed to protect from short circuits. It will activate and open the breaker when the current flow exceeds its rated value.

Conclusion

03420828HXL is a fuseholder designed to protect electrical circuits from overloads or short circuits. It is suitable for many industrial and commercial applications and is easy to install and use. It is a thermal magnetic circuit breaker type fuseholder, which combines two processes to protect the circuit: thermal protection and magnetic protection. 03420828HXL is a reliable and cost-effective solution for protecting electrical circuits.
