Circuit breakers are an essential safety feature in any electrical system. They are designed to detect an overload or short circuit in the system, and then automatically disconnect the power to prevent any damage from happening. The UPG4-8922-1 is a type of circuit breaker designed to handle high current applications. It is a UL and CSA listed device, and is available in different sizes with various ratings.

The UPG4-8922-1 is a three-pole device, with each pole rated for up to 20,000 amperes of current. It is generally used in high-current applications such as power distribution systems, industrial motor control centers, and emergency power supplies. The device has two main functions: motor protection and overcurrent protection. The motor protection function helps to prevent damage to motors due to overheating or current fluctuations, while the overcurrent protection feature detects any current that is higher than the design capacity of the breaker.

The UPG4-8922-1 features a three-step trip curve design. The first step is a standard overload trip, which allows the device to quickly open if the current load exceeds the rated value. The second step is a long-time delay trip, which can help to protect motors and other electrical components from damage due to thermal overloads. Finally, the third step is an instantaneous trip, which will open instantaneously in the case of any short circuit or other extreme overloads.

The UPG4-8922-1 is designed to be used in applications where it must operate reliably under harsh conditions, such as high temperature, vibration, or moisture. Additionally, the device is designed to be corrosion-resistant and shock-resistant, withstanding vibration up to 100G. It also features integrated surge protection to help protect against power surges and lightning strikes.

The UPG4-8922-1 is a reliable and durable circuit breaker that is designed to provide reliable protection against electrical hazards. The trip-curve design ensures that the device can react quickly to any overcurrent or short circuit condition, while the surge protection helps protect against power surges and lightning strikes. And the shock-resistant and corrosion-resistant features ensure that the device can withstand harsh conditions. With its high current handling capacity and reliable protection features, the UPG4-8922-1 is an ideal choice for high current applications.
