Introduction

Circuit breakers are essential components in electrical systems used to prevent an overload. Without circuit breakers, a short circuit or other strong electrical current overloads could quickly cause costly and dangerous damage. IUGH62-35499-1 is a manual operation circuit breakers used to control and protect circuits and equipment from damage due to overcurrent, overload, and short circuit. In this article, we discuss the application field and working principle of IUGH62-35499-1.

Application Field

IUGH62-35499-1 circuit breakers are used in circuits with AC nominal voltage between 230V and 500V, rated current not exceeding 63A, and mounted on DIN rails. They offer a very high quality of protection against overcurrent and short circuit. They are mainly used in residential areas but can also be applied in industrial control distribution systems.

Working Principle

When an overcurrent or short circuit occurs, the IUGH62-35499-1 circuit breaker trips to cut off the circuit and thus protect the circuit from damage. To start the breaker, a handle is pressed down or pulled up to the “ON” position. To trip the breaker, the handle is moved to the “OFF” position.The mechanism of the IUGH62-35499-1 circuit breaker works by detecting the magnitude of the current and tripping the breaker when it reaches the overcurrent level. It operates according to a “time–current characteristic”, which is a curve that illustrates how the circuit breaker trips at different magnitude of current and time.When the main current surpasses a threshold, the trip time of the circuit breaker is determined by the position of the actuating arm and the inertia disk of the mechanism. A higher position of the actuation arm means a longer trip time at the same magnitude of overcurrent. The breaker will trip rapidly at low overcurrents and trip more gradually at higher currents.

Conclusion

IUGH62-35499-1 manual operation circuit breakers are used in circuits with AC nominal voltage between 230V and 500V, rated current not exceeding 63A, and mounted on DIN rails. It offers high quality protection against overcurrent and short circuit. The mechanism of the circuit breaker works by detecting the magnitude of the current and tripping the breaker when it reaches the overcurrent level. This article has discussed in details the application field and working principle of the IUGH62-35499-1 circuit breaker.
