Circuit breakers are essential components of any electrical circuit, designed to provide protection against electrical overloads and short circuits. The IULNPK11-35272-150 is a high-performance circuit breaker designed for medium-voltage applications up to 35kV.

The IULNPK11-35272-150 circuit breaker is a three-pole, air magnetic circuit breaker that provides short-circuit protection and overload protection. It is characterized by its lightweight construction and stable performance with low power consumption. Its high breaking capacity and excellent interrupting performance make the IULNPK11-35272-150 circuit breaker ideal for a wide variety of applications, including renewable energy systems, industrial plants, household appliances, large mechanical and electrical machines, as well as power distribution systems.

The working principle of the IULNPK11-35272-150 circuit breaker is simple and effective. When an overload or short circuit occurs, it interrupts the flow of electricity and trips the breaker off, preventing further damage to the electrical circuit. This is done by means of a magnetic force created by a current-responsive coil, which creates an opposing magnetic field that acts on a movable contact arm, pushing it away from the main contact point to open the breaker. Due to the magnetic field, the contact arm is then held in the open position, preventing further current flow until the breaker is reset.

The IULNPK11-35272-150 circuit breaker also features an adjustable tripping mechanism, adjustable electronic time-delay relays, and adjustable sensitivity adjustments to ensure accuracy and efficient operation. In addition, it also has arc-extinguishing performance, providing additional protection against electrical arc faults. All these features make the IULNPK11-35272-150 circuit breaker an ideal choice for medium-voltage circuits.
