Circuit breakers are essential electrical components which protect systems, people, and machines from power surges or unexpected power overloads. The IULHK11-39065-3 is a single-pole temperature sensitive thermal-magnetic circuit breaker designed to protect residential electric circuits from overloading and short circuits. It is rated at 10 Amp and has a rated voltage of 250V AC.

The thermal-magnetic circuit breaker has two components which work together to protect residential electrical circuits from overloading and short circuits. The first is a bimetallic strip, which is a thin piece of metal with two dissimilar metals welded together. When the current passing through the bimetallic strip rises, it causes the alloy to expand. This expands the strip width and causes it to bend, increasing the distance between the contacts and thus breaking the circuit. This mechanical action is what protects the circuit from overload.

The second component of this circuit breaker is a magnetically operated switch, which works in conjunction with the bimetallic strip. This switch is connected to a solenoid coil. When the current passing through the breaker exceeds the rated current, the current energizes the solenoid coil, which then pulls the switch to a point at which the circuit is opened, thus breaking the circuit.

The IULHK11-39065-3, being temperature sensitive, is designed to respond quickly to heat changes in the area around it. As such, if the temperature of the area around the breaker exceeds the maximum rated temperature, it will automatically switch off the circuit, thus protecting it from overheating. In this way, it ensures the safety of those in the vicinity.

Overall, the IULHK11-39065-3 circuit breaker is an effective and efficient way of protecting residential electric circuits from potentially dangerous power overloads or short circuits. Its combination of mechanical and magnetically operated components provides a reliable and efficient level of protection. Furthermore, its temperature sensitive nature ensures it will respond quickly to sudden rises in the ambient temperature, providing further protection for residents and their property.
