Circuit Breakers

Circuit breakers are switch-like electrical safety devices which protect against excessive electrical currents. They can be used to protect electrical wiring, appliances, and other components from damage caused by overload. The UPG11-1773-1 is a circuit breaker specifically designed for high-voltage applications. It is a multi-stage, thermal-magnetic circuit breaker with a rated operational voltage of 1000 VAC or 1500 VDC.

UPG11-1773-1 Application Field

The UPG11-1773-1 is designed for a wide range of applications. It is commonly used in high-voltage applications as part of the power distribution system. It is suitable for both indoor and outdoor applications. It can be used in telecom and industrial environments. It is also commonly used for main power lines, back-up power supplies, and emergency power systems.

UPG11-1773-1 Working Principle

The UPG11-1773-1 features a multi-stage, thermal-magnetic trip mechanism. This means it has two separate mechanisms for detecting over-currents and tripping the circuit breaker. The first mechanism is a thermal setting, which uses a bimetallic strip that can detect when the current flow is exceeding the safe limit. When this happens, the strip will bend and cause the circuit breaker to trip. The second mechanism is a magnetic setting, which is used to detect very high current flows. This setting uses a magnetic field to detect the current flow and trigger the trip mechanism when the current flow is too high.

Overall, the UPG11-1773-1 is designed for a wide variety of application fields and offers high performance and reliability. Its multi-stage, thermal-magnetic trip mechanism ensures that it can protect against both short-term and long-term current overloads.
