Introduction

Circuit breakers are important pieces of safety equipment for industrial, commercial, and residential electrical systems. They provide protection against electrical faults, such as over-voltage, over-current, and short circuits, as well as protection against fire and other hazardous conditions. The IUG21-39918-16 circuit breaker is a robust, reliable, single-phase, three-pole unit designed for industrial applications. This article will discuss the features and working principles of the IUG21-39918-16 circuit breaker, with a focus on the application field.

Application Field

The IUG21-39918-16 circuit breaker is rated for currents of up to 16A and can be used in a wide range of applications including:• Industrial Settings: Factories, workshops, and other industrial settings rely on circuit breakers to provide safety for personnel and equipment. The IUG21-39918-16 is designed to provide maximum protection in these environments, withstanding temperatures up to 131°F.• Commercial Applications: Businesses of all sizes use circuit breakers for protection and to maximize the efficiency of electrical systems. The IUG21-39918-16 is an excellent choice for these applications, providing reliable and effective protection.• Residential Applications: Homes and other residential buildings use circuit breakers to prevent dangerous situations associated with power surges. The IUG21-39918-16 is UL-listed, ensuring that it has been tested and proven to be a safe and reliable breaker for these applications.

Working Principle

The IUG21-39918-16 circuit breaker uses a thermal-magnetic trip unit, meaning that the breaker is sensitive to both increases in temperature and increases in current. The thermal components are designed to detect changes in temperature that could indicate a short circuit or dangerous overload condition. When activated, they open the circuit quickly and effectively, preventing further damage.The IUG21-39918-16 also uses magnetic protection components to detect increases in current. When current reaches a certain point, the magnetic forces in the trip unit activate, opening the circuit before catastrophic damage can occur.

Conclusion

The IUG21-39918-16 is a robust, reliable, and UL-listed three-pole, single-phase circuit breaker designed for use in industrial, commercial, and residential settings. It utilizes a thermal-magnetic trip unit to detect changes in temperature and current, and quickly activate and open the circuit when necessary. This feature ensures maximum safety and protection in all applications, making it an excellent choice for a wide range of needs.
