Circuit breakers are key elements of an electrical power system. They are utilized to interrupt current in case of extreme conditions, protecting downstream systems and personnel from injury. The UPG666-24257-15 model of circuit breaker is one of the most popular circuit breakers available on the market today. In this article, we will discuss the application field and working principle of a UPG666-24257-15 circuit breaker.

UPG666-24257-15 circuit breakers are used in a variety of applications. The most common of these is as the main switch in service entrance panelboards and in load centers. This type of circuit breaker is designed for use in low voltage (240 VAC) residential and light commercial applications. As the main switch, the circuit breaker provides both overload and short-circuit protection for all circuits downstream of it. The UPG666-24257-15 is also suitable for motor loads, such as compressors, pumps, and fans, and can be used in range, stove, and dryer circuits.

The UPG666-24257-15 circuit breaker operates on the thermal-magnetic principle. When it is energized and an overload or short circuit condition is present, an internal bi-metal strip expands and causes the trip mechanism to open the breaker’s contacts. The speed with which this happens is controlled by a combination of the size of the internal current transformer and the design of the bi-metal strip. The trip mechanism is also tamper-resistant so that it cannot be reset when it has tripped.

The UPG666-24257-15 circuit breaker is UL 489-Listed and meets the standards of the National Electric Code. It is designed to provide superior protection against both overloads and short circuits. It provides an adjustable trip setting range from 20 to 60 amperes. It also features a trip indication flag that is visible from outside the enclosure, allowing quick identification of a tripped breaker. The circuit breaker also features an auto-reset operation, allowing it to reset itself after a power outage or other overload condition.

The UPG666-24257-15 circuit breaker is a reliable and user-friendly circuit breaker suitable for use in a wide variety of applications. Its applications range from residential and light commercial applications to motor loads, such as compressors, pumps, and fans. The circuit breaker operates on the durable thermal-magnetic principle and features adjustable trip settings and a visible trip indication flag. It is UL- 489 listed and meets the standards of the National Electric Code. It is a reliable and cost-effective option for providing superior protection against both overloads and short circuits.
