Circuit breakers are electrical protection devices designed to ensure the safety of electrical circuits from damage caused by overcurrent, short circuit, and ground faults. A 1G15UM is a type of circuit breaker that is used to protect medium-voltage installations from overloads and short circuits. It is suitable for both indoor and outdoor use from 0.23 kV up to 5.6 kV.

The basic purpose of a 1G15UM circuit breaker is to interrupt the circuit flow and protect the electrical circuit when the current reaches a point that may cause damage. This is done by a device called a trip unit, which detects when a certain amount of current or voltage is exceeded and activates the breaker. When the trip unit activates, the breaker trips and opens, disconnecting the current flow. This protects the circuit and the people connected to it from harm or damage.

A 1G15UM circuit breaker is also equipped with a thermal-magnetic trip unit, meaning that it can detect both overcurrent and over temperature. The thermal-magnetic trip unit is designed to detect when the current is too high and reach a level that can cause overheating, and the magnetic trip unit is designed to detect when a short circuit is present. Both of these devices help to protect the circuit from damage.

The 1G15UM circuit breaker features a compact design, easy installation, and a built-in relay for ease of access and control. It also features indicator LEDs which show whether the breaker is activated and in operation. The breaker also has fault current ratings ranging from 10-46 kA, making it suitable for a wide range of applications.

The 1G15UM circuit breaker is an important component in any electrical system, and its use helps to ensure the safety of the system, its components, and the people that use it. This makes it an essential part of any electrical system.
