Circuit breakers are essential safety devices in electrical systems and have been widely used in many industries such as aerospace, commercial, railway, automotive and marine industries. They are used to protect against short-circuiting, over-loading and over-voltaging of electrical circuits. LEGH66-1-62-30.0-AZ-91-V is an advanced medium-voltage circuit breaker that is designed for use in challenging field/environmental applications.

The LEGH66-1-62-30.0-AZ-91-V is designed with a two-step voltage limitation system. The circuit breaker is set to react to both high and low voltage scenarios, meaning that it will turn off the power in a swift and precise manner in the case of overvoltage or undervoltage. The design of this breaker features two separate operations to ensure reliable protection against dangerous overvoltages and undervoltages.

Besides its two-step voltage limitation system, the LEGH66-1-62-30.0-AZ-91-V is also constructed with a contact protection system. This design feature ensures the protection of contacts against corrosion, oxidation, and erosion. The contact protection system is also designed to abolish any welding effects which could lead to the systems’ failure. Additionally, all LEGH66-1-62-30.0-AZ-91-V circuit breakers are ideally appropriate to be used in both outdoor and indoor installations, making them a suitable choice for challenging field & environmental applications.

The LEGH66-1-62-30.0-AZ-91-V is also equipped with a robust operation system that stands strong against variable load changes. The breaker responds quickly and accurately to these changes and prevents any electrical damage which could arise from the continuous electric current running through it. By continuously monitoring the circuit’s load, the LEGH66-1-62-30.0- AZ-91-V is able to detect any overloading and overvoltage, and then trips the circuit immediately.

All LEGH66-1-62-30.0-AZ-91-V circuit breakers are provided with a thermodynamic servo release system that constantly monitors the temperature and current within the circuit. This mechanism has been designed to protect the circuit breaker by avoiding any contact sticking, an occurrence which can occur when the contacts remain closed when the tripping mechanism trips the circuit breaker. This servo release system also keeps the breaker’s response time as fast as possible so that the circuit breaker will trip the circuit within a few milliseconds of an overload or short-circuit.

The LEGH66-1-62-30.0-AZ-91-V circuit breaker carries significant advantages by being compact while providing stable operation in high-speed and switching processes. This advanced circuit breaker is certified to be used in many different applications such as aerospace, commercial, railway, automotive and marine industries. Its combination of high-quality components, reliable construction, and scientifically-proven features make the LEGH66-1-62-30.0-AZ-91-V a suitable option for challenging environmental applications.
