Circuit breakers have been around for decades and play a critical role in keeping people and equipment safe from over-currents and short-circuits. UPL1-27936-7, also known as a low-voltage drawout circuit breaker, is a device designed to protect circuits from mechanical, thermal and electrical overloads, as well as against contact arcing. It is used in electrical systems to break circuits and thus protect personnel and equipment from injury and fire.

UPL1-27936-7 is a three-pole circuit breaker with induction trip technology. It has a separate construction design, which includes a main contact group, main protective apparatus and draw out mounting frame secured together in a single unit. In general, this type of circuit breaker has two main parts: the main contactor and the arcing contacts. The main contactor is a mechanical device that carries the electrical load and opens the circuit when the load is too large. The arcing contacts contain an arc extinguish chamber and enable the high-voltage arcs caused by an overload or short circuit to be safely contained. When an overload or short circuit is detected, the main contactor opens and the arcing contacts in the arc chamber separate, suppressing the electrical arc.

The working principle of UPL1-27936-7 is based on the fundamental principle of electromagnetic induction. That is, when a current passes through a coil, an electromagnetic field is generated which then interacts with a small magnet within the circuit breaker, causing a bimetallic strip to bend. The amount of bimetallic strip bending is proportional to the load current, and when the load current passes a predetermined threshold level, the bimagnetic strip bends further and activates the circuit breaker trip. This causes the main contactor to disconnect the load from the power source, thus preventing the circuit from being overloaded or short-circuited.

The UPL1-27936-7 is suitable for a variety of applications, such as power distribution systems, lighting, heating systems, and even motor control applications. Being UL-certified and having been tested for high-voltage applications, it is an ideal choice for commercial, industrial, and residential applications. Its high-accuracy rating increases the prevailing confidence in the device’s stability and accuracy and the separate construction design allows it to easily be mounted in restricted spaces, such as metalclad switchgear.

In conclusion, UPL1-27936-7 is an ideal choice for many circuit breaking applications. It is designed with a separate construction that enables it to easily be mounted in restricted spaces, and it operates on the principle of electromagnetic induction, thus ensuring high accuracy and reliability. Its UL-certification and high-voltage ratings make it suitable for industrial, commercial, and residential applications, and it is an ideal choice for protecting circuits from overloads and short-circuits.
