Circuit Breaker is an important electrical switching device used to prevent electrical circuits from being overloaded or short-circuited. The IULR1-1-52-50.0-91 Circuit Breaker, also known as a thermal-magnetic circuit breaker, is a specially designed breaker for use in the protection and control of low voltage equipment.

Application Field and Working Principle of IULR1-1-52-50.0-91

The IULR1-1-52-50.0-91 Circuit Breaker is a combination device for the protection of overload and short-circuit conditions. It can be used in a wide range of low voltage AC applications, such as in residential, commercial and industrial settings. The main components of this device are a thermal-magnetic protection, an electronic trip unit and a mechanical actuator.

The thermal-magnetic protection consists of a combination of an independently adjustable thermal element and a bimetallic actuator. The thermal element is used to detect the current overloads and control the circuit breaker opening when the current reaches a predetermined setting. The bimetallic actuator is used to detect the presence of a short circuit and open the circuit breaker when the current reaches a predetermined level. The thermal element is sensitive to excessive temperature and reacts to high levels of temperature before the bimetallic actuator. This is why this device is combination of two types of protection elements.

The electronic trip unit allows for the user to program settings for the current thresholds that will make the circuit breaker trip. This unit is also used to monitor the circuit breaker for any faults or anomalies. If the unit detects any faults or anomalies, it will automatically detect the fault and trip the circuit breaker.

The mechanical actuator is used to control the circuit breaker opening and closing. This is done by a series of springs and levers, which are controlled by the use of a handle on the front of the device. The actuator is used to open and close the circuit breaker while the electronic trip unit is used to detect the fault or anomaly.

These components work together to provide overcurrent protection, short circuit protection and even surge protection. When a load exceeds a predetermined safe level, the thermal elements in the device detect the overload and initiate the circuit breaker opening process. As the current reaches a set level, the bimetallic actuator detects the presence of a short-circuit and trips the breaker. Finally, the mechanical actuator will open the circuit breaker, disconnecting the faulted circuit from the power source.

The IULR1-1-52-50.0-91 Circuit Breaker is a reliable and cost-effective solution for a variety of applications. It is widely used in residential, commercial and industrial settings as well as in medical applications that require reliable protection. This device can provide protection from both overload and short circuit conditions, making it an ideal choice for low voltage applications.
