Circuit breakers are an essential component of modern electrical systems, and the R21-2-15.0A-R101EV-S is a robust and reliable breaker design intended for residential, industrial and commercial applications. This article will explain the application field and working principle of this breaker.The R21-2-15.0A-R101EV-S breaker is designed for use in a wide range of residential and commercial applications, including residential homes, factories, warehouses, and offices. Its capability to accept alternating current ratings from 10 to 15 amps makes it an ideal choice for controlling the electric power supply to heavier-duty electrical equipment, such as large appliances, air conditioners, and heat pumps.The breaker is rated for interrupting up to 2,000A at 480V or 2,200A at 277V, which is more than sufficient for residential, commercial, and light industrial applications. Additionally, its solderless terminals provide superior connection security and its mounting brackets ensure easy installation.At the heart of the breaker is a thermal-magnetic trip curve that enables it to trip quickly in the event of an overload or short circuit. The internal thermostat of the breaker is designed to operate using either a standard off-the-shelf thermostat or one that is tailored to the specific circuit application. The basic working principle of the breaker is as follows:When current flows through the breaker, it generates heat, which is measured by the internal thermostat. If the current level reaches a pre-determined threshold, the thermostat initiates the breaker\'s electronic trip curve that causes the circuit breaker to trip. The breaker will reset itself once the temperature of the device has returned to normal. The breaker also features an electrical trip curve reset mechanism which can be used to reset the breaker in the event of an unwanted power outage.The R21-2-15.0A-R101EV-S breaker is a reliable and durable breaker suitable for a variety of applications. Its thermal-magnetic trip curve provides excellent protection against overloads and short circuits, while its solderless terminals allow for easy and secure connections. It is an ideal choice for protecting the power supply to heavier-duty electrical equipment, such as large appliances, air conditioners, and heat pumps.
