Circuit breakers are a fundamental part of the electrical system, protecting appliances, circuits, and parts of the electrical system from overcurrents and circuit faults. The IULK2-39261-80, much like other circuit breakers, is designed to provide reliable and safe protection of electric circuits in a wide range of industrial and commercial applications.

The IULK2-39261-80 is a three-phase circuit breaker which comes in a solid and reliable design. It is constructed with a breaker main contact to protect from faults and overloads and is rated to handle a maximum of 125 Amps of current. The three phase circuit breaker also includes an auxiliary contact which can be used for signaling or controlling external circuits.

The IULK2-39261-80 is typically used in industrial and commercial applications for providing electrical short circuit protection in AC power systems. It is suitable for installations up to 690 Volts AC, rated for breaking capacities up to 100 KA and with a short circuit interrupting rating of up to 25 KA. It is designed to withstand abnormal voltage and temperature conditions and meet all international safety standards.

The working principle of the IULK2-39261-80 is relatively simple. When the current is measured to be above the set current level, the circuit breaker will trip and cause it\'s associated circuit to open. The actual tripping process occurs when a magnetic field, generated by the currents flowing through the circuit breaker, exceeds a certain threshold. This ballasts the current, tripping the breaker and safely completing the current interruption.

The IULK2-39261-80 has a wide variety of selectable features such as adjustable time delay, automatic reset, manual reset, and horizontal mounting. This allows the circuit breaker to be used in a variety of applications. Additionally, the circuit breaker comes with a UL1077 safety rating, making it suitable for protecting large machinery, commercial facilities, and AC motor circuits.

In summary, the IULK2-39261-80 is a reliable three-phase circuit breaker, used mainly in industrial and commercial settings. It offers a wide range of selectable features, making it suitable for a variety of environments. It comes with a UL1077 safety rating, making it suitable for protecting larger machinery, commercial facilities, and critical AC motor circuits. The working principle of the IULK2-39261-80 is based on the measurement of the current and the generation of an electrical field, which in turn trips the breaker and safely interrupts the current.
