Circuit breakers are a type of electrical safety device that mounts on the electrical panel of homes and industrial facilities to protect against overloads, shorts, and other possible malfunctions. The UPL11-31369-2 circuit breaker is a three-phase, circuit breaker with four-pole switching capacity for medium voltage applications. It is designed to be used with three-phase AC motors and other electrical systems.

The UPL11-31369-2 circuit breaker features high continuous current and short-circuit ratings, making it suitable for protection and switching in systems with higher rated current. It is also equipped with an electromagnetic relay for trip circuit monitoring and a manual operation handle for manual testing.

The UPL11-31369-2 is a popular choice for industrial applications such as HVAC, marine, and factory automation systems. It is available in both panel mount and freestanding versions, with the panel mount version having the highest continuous current rating of 70 A.

The UPL11-31369-2 operates on a simple yet effective principle: when the current level exceeds a set limit, the bimetal strips in the breaker will heat up and expand, causing a plunger to trip the breaker and shut off power to the system. This prevents the system from being damaged by an overload or short.

The UPL11-31369-2 is designed for both residential and light commercial applications. It is UL Listed, meeting all safety standards and providing users with a lifetime of reliable, energy-efficient protection. This circuit breaker cannot be reset manually, but an auxiliary switch allows for circuit testing and it can be reset through the switch.

In addition to its high current ratings, the UPL11-31369-2 offers several features that make it an attractive option for industrial applications. It has an adjustable current trip level, meaning that it can be calibrated to match the current level of your particular system. This means that your system is never overloaded and it is always operating within its recommended parameters.

The UPL11-31369-2 also offers exceptional insulation material, meaning it is highly resistant to arc fault current. This makes it suitable for a wide range of industrial applications, both residential and commercial. It is also resistant to corrosion and environmental fluctuations, meaning it is well-suited for outdoor installations.

The UPL11-31369-2 circuit breaker is a popular option for medium voltage applications, offering reliable, energy-efficiency, and ease of installation. With its adjustable trip level, solid insulation material, and corrosion-resistant design, it is a great choice for protecting your system in harsh environments.
