Circuit breakers are essential components of any electrical system. They protect both personnel and equipment when an overcurrent or other hazardous current occurs in the system. The LELH111-31364-4, made by the company LELH, is a circuit breaker designed for the protection of larger systems and components, such as transformers, switchgear, and other high-voltage systems. This article will explore the application field of the LELH 111-31364-4, as well as its working principle.

The LELH111-31364-4 is designed for the protection of medium-voltage electrical circuits, such as those found in industrial and commercial locations. The breaker is suitable for currents up to 5kA and can be connected to single-phase, three-phase, or split-phase electrical systems. In addition, the breaker has numerous safety features designed to protect personnel and equipment from dangerous overcurrents. These include short-circuit protection, overload protection, and thermal protection against rising temperatures. The LELH111-31364-4 also has a built-in fault indicator, allowing technicians to quickly identify and isolate a fault when one occurs.

The LELH111-31364-4 works by sensing the circuit current, and, if the current exceeds the breaker’s pre-determined trip point, the breaker will automatically open the circuit. This action prevents hazardous currents from flowing through the system and protects the equipment from damage. The LELH111-31364-4 uses a combination of thermal and magnetic tripping mechanisms to achieve this. When an overcurrent is detected, the breaker will first open the circuit using its thermal component. If this does not sufficiently reduce the current, a magnetic field will then be created and the circuit will be opened using this additional method. In either case, the breaker will remain open until the current is brought back within its pre-determined limits.

The LELH111-31364-4 is a reliable and highly efficient circuit breaker that can be used to protect a wide range of electrical systems and components. Its combination of thermal and magnetic tripping mechanisms ensures a fast and efficient response when an overcurrent is detected, while its various safety features provide further protection against hazardous currents. By making use of the LELH111-31364-4 circuit breaker, technicians and electricians can be reassured that their electrical systems are reliably and safely protected.
