Introduction

Circuit breakers are devices used to protect electrical systems and components from overload or short-circuiting. They provide a safe and efficient way to interrupt high-voltage or power cycles to prevent damage to the components and to people. The IEGH11-33128-7-V circuit breaker is one such product that is specifically designed to meet certain safety and performance requirements. This article examines the application field and working principle of the IEGH11-33128-7-V circuit breaker.

Application Field

The IEGH11-33128-7-V circuit breaker is designed to be used in the low-voltage electrical distribution boards of 600 Volts or less. It has a pickup voltage ranging from 6-30 Volts. It is also UL recognized and approved, making it suitable for use in domestic contexts. It is also recommended for applications that involve motor loads in commercial, residential, and industrial settings.

Working Principle

The IEGH11-33128-7-V circuit breaker employs an self-adjusting overload protection system. The system functions by the use of a bimetallic strip, which is designed to heat up when a high-current situation is detected. As the strip heats up, it bends and ultimately trips a self-adjusting switch, thereby interrupting the current and disconnecting the power.The bimetallic strip is designed to move through a predetermined process to actuate the circuit breaker. As the current passes through the strip, it heats up. As it heats up, it bends increasingly, which pulls against electric terminals. As it pulls against these terminals, it triggers a movable contact, which trips the breaker. The actuation mechanism is designed to be able to detect and recover low influxes, such as those due to motor inrush and start-up, without tripping.The IEGH11-33128-7-V circuit breaker also features a manual trip function. This allows the user to manually initiate a trip of the breaker in the event of a power surge. It also features an electromagnetic protection system, which acts as a backup in the event that the bimetallic strip fails to trip the breaker.

Conclusion

The IEGH11-33128-7-V circuit breaker is a reliable and safe device for protecting electrical systems and components from overload and short circuiting. It is specifically designed for low-voltage applications in domestic, commercial, and industrial settings. The circuit breaker employs an self-adjusting overload protection system, which utilizes a bimetallic strip, and also features a manual trip function and a backup electromagnetic protection system.
