Circuit breakers are increasingly becoming an integral part of modern electrical systems and for a good reason. Circuit breakers protect people and home appliances, by automatically disconnecting the power if an overload or short circuit is detected. The UPG4-5538-1 is a specific type of circuit breaker that offers a wide range of applications in residential, commercial, industrial, and other specialty circuits. In this article, we will briefly look at the application field and working principle of the UPG4-5538-1 circuit breaker.

The UPG4-5538-1 circuit breaker is a three pole breaker, designed for use in 120V and 240V circuits. It is rated between 15 and 40 Amps and is available in single or double-pole options. The single-pole option is suitable for use in applications such as bathroom circuits, laundry rooms, garages, dens, and bedrooms, whereas the double-pole version is perfect for dedicated circuits such as kitchen appliances, heating systems, and outdoor lighting. Both single and double pole UPG4-5538-1 circuit breakers have a maximum trip current rating of 10kA. Additionally, they are made from an impact-resistant and flame-retardant thermoplastic enclosure.

At the heart of the UPG4-5538-1 circuit breaker is a thermal-magnetic tripping mechanism. This mechanism consists of a bimetallic strip and a magnetic circuit. When the circuit is closed, current passes through the bimetallic strip, which heats up and expands. When the current exceeds the rated value, the bimetallic strip will expand and release the latch, which in turn opens the circuit breaker. This cutting-off of the current prevents any electrical shock or damage to certain appliances, wiring, and other electrical components. Additionally, the magnetic circuit acts as an overcurrent protection by instantaneously tripping at a higher current level, thereby providing extra protection.

The UPG4-5538-1 circuit breaker is a dependable yet cost-effective choice when it comes to protecting electrical systems. Not only is it UL listed, but it also features advanced electronic trip unit technology, which provides superior protection against overloads, short circuits, and ground fault circuits. In addition, its modern design ensures easy installation and long-lasting performance.

In conclusion, the UPG4-5538-1 circuit breaker is an excellent choice when it comes to protecting electrical systems from dangerous overloads and short circuits. It is suitable for use in a wide range of residential, commercial, industrial, and specialty circuits, and its advanced electronic trip unit technology, thermoplastic enclosure, and attractive design make it a cost-effective and reliable solution for protecting your electrical system.
