Circuit breakers are a vital part of modern electrical systems, providing necessary protection from overloading or other dangerous conditions. They come in a variety of shapes and sizes, from small residential devices to large industrial or commercial equipment. One type of circuit breaker in particular, the UPL111-27936-3, is used in a variety of settings for safety applications. This article will discuss the application field and working principle of the UPL111-27936-3.

The UPL111-27936-3 is a medium-sized, three-pole electrical circuit breaker designed for use in commercial and industrial settings. It is unique in that it contains a built-in switch, allowing the user to quickly and easily switch the breaker on or off. This is often convenient in regulating electrical loads on machinery or equipment, ensuring that no one appliance or device is receiving too much power.

The UPL111-27936-3 also has a built-in current sensing relay. When the current draw exceeds a certain threshold, the relay triggers the breaker to trip, cutting off the current supply. This helps to prevent the build-up of dangerous heat, as well as overloading the device or wiring, both of which can cause permanent damage.

One of the main applications for the UPL111-27936-3 is in industrial motor control systems. In these settings, the breaker works to protect both the motor and the surrounding wiring from any operation beyond its safe limits. It is also designed to handle the varying load demands of the motor, as most motors will require more power at times than they do during operation at lower speeds.

The UPL111-27936-3 can also be used in other application fields, such as in the protection of electronic equipment from hazardous power fluctuations. Although these power surges are generally short-lived, they can be dangerous to vulnerable components if they are not quickly identified and addressed. The UPL111-27936-3’s current sensing relay is designed to detect any sharp spikes in the current draw and, if necessary, trip the breaker to protect the components.

In addition to its safety features, the UPL111-27936-3 is also equipped with a built-in auxiliary contact. This contact can be used to connect an external alarm system, alerting operators of an unexpected circuit trip. This can be particularly valuable in industrial settings, where circuit trips can potentially shut down production lines or other operations.

The UPL111-27936-3 is a medium-sized circuit breaker with safety and alarm features designed for use in commercial and industrial applications. In these settings, the breaker works to protect devices or machinery from overloading or other dangerous conditions, providing a dependable and essential safety measure. It is equipped with a built-in switch, current sensing relay, and auxiliary contact, making it an excellent option for use in motor control systems and electronic equipment.
