Circuit Breakers are primarily used to help protect people and equipment from electric shock, over-temperature or overloads. They can also be used to guard against spikes in power use or to provide additional safety features in large industrial and commercial electrical systems. The 1E15UM application field and working principle is just one of many types of circuit breakers available today.

The 1E15UM has a rated current of 15 A, making it suitable for applications where an overload protection is required for a wide range of current levels up to 15 A. It is capable of interrupting an overload or short circuit current as much as 10,000A in no more than 30 milliseconds. The device also has an adjustable trip range that can be tailored to meet the exact needs of the application.

The 1E15UM utilizes the principle of magnetic force to open the circuit when an overload or short circuit is detected within the device. The operating mechanism consists of a bimetallic strip and an adjustable trip coil. The bimetallic strip expands or contracts due to changes in temperature created by an overload or short circuit. This action moves a lever attached to the adjustable trip coil which then produces a magnetic field. This magnetic force pulls against a pivoted armature which then opens the circuit.

The 1E15UM also contains a bi-directional element containing a pair of solid state contacts. When the circuit is energized, a current flows through the coil, causing it to magnetize the contacts. When the overload or short circuit condition is detected, the contacts open and the current flow turns off. This action of breaking the circuit helps to protect against further damage in the system.

Apart from the overload or short circuit protection, the 1E15UM also provides the necessary protection of personnel and equipment against electric shock and short circuits. The bimetallic strip and adjustable trip coil are incorporated into the device to provide this additional protection. The adjustable trip coil allows for the current flow to be interrupted at a predetermined level. This helps to reduce the potential for electric shock or damage to equipment due to a severe overload or short circuit.

The 1E15UM is suitable for a variety of applications. It can be used to provide overload protection for a wide range of current levels up to 15 A and to help protect personnel and equipment from electric shock or overloads. In addition, the adjustable trip coil helps to minimize the potential for electric shock and damage to equipment due to a sudden overload or short circuit. With its adjustable trip range and proven reliability, the 1E15UM can provide an excellent level of circuit breaker performance.
