Circuit breakers are essential components of any electrical system, and the IULHPK12-38515-150 is a prime example of this technology. This circuit breaker is designed to protect circuits from thermal overloads, excess currents, and automatic switching off of the power in the event of an overload or short circuit. In this article, we will take a closer look at the application field and working principle of this circuit breaker.

Application Field

The IULHPK12-38515-150 is a single-phase circuit breaker designed for residential and commercial applications. It is designed to protect light-duty motor loads such as pumps, air conditioners, heaters, and other motor-driven equipment. It can handle a nominal voltage of 125 volts AC and a maximum current of 15 amps. It also comes with a manual reset handle for manually switching off the power in the event of an overload or short circuit.

The IULHPK12-38515-150 is designed for indoor use only; it should not be used in outdoor applications. It also comes with a UL-listed interrupting capacity of 10 kA@120VAC, which is suitable for residential and commercial applications.

Working Principle

The IULHPK12-38515-150 circuit breaker operates using a thermal tripping principle. This means that when the temperature of the device exceeds a certain level, it will trip and automatically switch off the power. This is done to protect the circuit from thermal overloads, such as an excessive current or a short circuit.

The device comes with an adjustable thermostat that allows the user to adjust the temperature at which it will trip. This makes it easier to customize the breaker for specific applications, as well as providing extra protection in the event of an overload or short circuit.

The IULHPK12-38515-150 circuit breaker also comes with a differential trip function. This feature allows the device to detect an imbalance in the current, and when the imbalance exceeds a certain level, the breaker will trip and switch off the power. This is done in order to protect the circuit from ground faults, which can result in overheating and damage to the equipment.

Finally, the IULHPK12-38515-150 also comes with a mechanical indicator to show when the breaker has tripped. This makes it easy to identify a problem with the device, as well as providing an indication of when maintenance is required.

In conclusion, the IULHPK12-38515-150 is an ideal choice for residential and commercial applications. It can protect circuits from thermal overloads, excess currents, and automatic switching off of the power in the event of an overload or short circuit. Thanks to its adjustable thermostat, differential trip function, and mechanical indicator, it is highly reliable and effective at protecting circuits.
