The 1G4UM is a combination of two important circuit breaker technologies: the cutter circuit breaker and the dual-hump arc-chute. Developed by ABB, the combination of these two technologies as a unified whole was designed to provide an advanced level of safety and reliability. The use of the 1G4UM is well suited for a wide range of applications from residential to industrial environments, making it an ideal solution for many different scenarios.

The 1G4UM was designed to provide advanced protection for areas when two circuit breakers are necessary for adequate protection. This means that the use of two circuit breakers is necessary: one being a traditional circuit breaker, and the other being the 1G4UM. The 1G4UM works in combination with the traditional circuit breaker by providing an increased level of protection. The 1G4UM works by preventing the arc current that may arise from an overcurrent fault from passing through the main contacts of the circuit breaker. It does this by providing an arc-chute, which is essentially a second arc-chute located between the two circuit breaker contacts. This arc-chute is equipped with an advanced arc-interrupting mechanism, which quickly shuts off the arc current before it passes through the main contacts of the circuit breaker.

The 1G4UM also features a built-in cutter circuit breaker, which is located in between the two circuit breaker contacts. This cutter switch works by cutting off the power supply to the load, if too much current is flowing through the circuit. This prevents any additional damage to equipment, and helps reduce the risk of fire. This is especially beneficial in industrial environments, where a significant number of faults can occur due to overloads.

In order to ensure that the 1G4UM works properly, it needs to be connected in a specific manner. The 1G4UM must be connected in series with the two other circuit breaker contacts, so that the arc-chute and the cutter switch can function properly. Additionally, the circuit breaker must be connected to the ground, so that any arcing or excess currents will be safely grounded away from the equipment. This also helps reduce the risk of potential shocks or fires.

The 1G4UM is an important addition to the world of circuit breakers and provides an enhanced level of safety and reliability. Its use in a variety of settings, from residential to industrial settings, ensures that it is a valuable addition to any safety and reliability system. With its advanced features and vast array of applications, the 1G4UM is a powerful and valuable tool.
