Circuit breakers are electrical safety devices used to limit the current flowing through devices and circuits. A breaker is designed to automatically open and close a circuit as needed to protect devices and people from electrical shock and other hazardous conditions. The 8345-F01A-R0M1-DB1B2B-30A circuit breaker is a medium voltage (MV) magnetic breaker designed to safely and reliably operate in industrial and commercial applications.

Application Field

The 8345-F01A-R0M1-DB1B2B-30A circuit breaker is specifically designed for use in industrial and commercial applications, including:

• Electric utilities and distributed power systems
• Motor control centers
• Portable generator and large motor applications
• Metal-enclosed switchgear
• Circuit breaker equipment in buildings and industrial complexes
• Power meter boxes

The breaker is designed to provide reliable operation and protection of circuits and equipment from the dangers of overloading or short-circuiting. The breaker is available in three sizes – 800, 1200, and 1600 amps – to meet the varying demands of different applications. The breaker utilizes an air gap between the primary contact and secondary contact to ensure a safe, reliable, and efficient operation.

Working Principle

The 8345-F01A-R0M1-DB1B2B-30A breaker functions by shutting off the flow of current when an overload or a short circuit occurs. The breaker is designed to be highly sensitive and quickly detect changes in current, and is capable of sensing both overloads and fault currents. When an overload or short circuit is detected, the breaker’s contacts open, interrupting the flow of electricity.

When the breaker senses a potentially hazardous situation, it will trigger a trip. This trip is an action that causes the breaker’s contacts to open and prevent the further flow of current. Trips occur due to electrical faults, overloads, or other circumstances that generate high or low current levels. The breaker is designed to be highly sensitive to such situations and is capable of responding quickly.

The 8345-F01A-R0M1-DB1B2B-30A circuit breaker is also equipped with a thermal automatic reset. This reset occurs when a high temperature is detected in the breaker, which can be caused by an overload. When a high temperature is detected, the breaker will automatically reset itself and allow the flow of current to resume as normal.
