Circuit breakers are an integral part of electrical systems. A 1G05UM circuit breaker is a type of circuit breaker used in medium voltage applications. It is designed to protect the electrical system and associated components when an overload or short circuit event occurs. The 1G05UM is a fast-acting, thermal-magnetic device that is easy to install, maintain, and reset.

Design and Features

The 1G05UM has a unique design that allows it to be used in a variety of applications. It has a two-pole, low-voltage, thermal-magnetic design with automatic reset. It has a rated voltage of 600VAC, a rating of 400A, and a power supply frequency of up to 400Hz. The trip time is adjustable, allowing for quicker or slower tripping depending on the application. The 1G05UM is built with an easy-to-install mounting base and is easy to maintain and reset.

The 1G05UM is designed for reliable operation in demanding power and utility applications. It features a built-in disconnect switch for emergency cutoff, a current-limiting feature that reduces damage in the event of an overload or short circuit, and a long, adjustable time delay before tripping. It also features a built-in light that indicates the status of the circuit breaker and is visible from the front and side of the unit.

Applications

The 1G05UM can be used in a variety of applications, including but not limited to:

• Industrial power systems
• Power distribution systems
• Power systems in buildings and buildings automation
• HVAC and motor control systems
• Data centers
• Distributed networks
• Renewable energy systems and Smart Grids
• Lighting and emergency systems

Working Principle

The 1G05UM is a fast-acting thermal-magnetic circuit breaker. The thermal element of the circuit breaker monitors the temperature of the electrical device and trips the circuit breaker when the temperature exceeds a preset safety threshold. The magnetic element monitors the current flow of the electrical device and trips the circuit breaker when the current flow exceeds an adjustable preset limit. The time delay feature of the 1G05UM allows for a longer or shorter time delay before the circuit breaker trips, depending on the application. The adjustable time delay can be set before the device is installed.

Conclusion

The 1G05UM is a fast-acting, easy-to-install, and easy-to-maintain thermal-magnetic circuit breaker. It is designed for reliability in medium-voltage applications, and it has a variety of features and applications. The 1G05UM\'s adjustable time delay, disconnect switch, and current-limiting capabilities make it an ideal device for a variety of power and utility applications.
