Circuit breakers are a critical component of any electrical system. They are used to protect circuits from short circuits, overcurrent, overloads, and other potentially hazardous conditions. The 285-111-30758-2 (FBX2) circuit breaker is one such device, designed specifically for applications where space is at a premium such as lighting, building automation, and control systems. This article provides an overview of the FBX2’s application field and working principle.

In terms of application, the FBX2 circuit breaker finds its use in a wide range of electrical systems. These include residential and commercial lighting systems, HVAC systems, industrial process controls, automated control systems, networking and communication installations, and other industrial equipment. Depending on the application, the FBX2 can be rated from 8A to 50A, making it suitable for low to medium current applications. In addition to its current ratings, the FBX2 has also been tested and certified according to UL489, IEC 60947-2, and CSA22.2-109 safety standards.

The FBX2 circuit breaker operates by monitoring both the current and the voltage in an electrical system. When either of these values exceeds the rated specifications for the breaker, the FBX2 opens the circuit, preventing further current flow and protecting the system from harm. It then sends notifications to the system operator, allowing for prompt corrective action. The FBX2 also has a built-in thermal protection that opens the breaker in the event of an overload.

The FBX2 is a compact and lightweight device, making it easy to install and maintain. It is designed to mount directly into an electrical box, allowing for an easy plug-and-play type installation. Additionally, the FBX2 has a mounting bracket with a built-in ground lug, which makes it easy to connect to the ground system. The FBX2 also features an easily accessible manual reset button, which allows for a manual reset if necessary.

In short, the FBX2 circuit breaker is a versatile and reliable device that is suitable for a wide range of applications. Its small size and easy installation make it ideal for space-constrained installations. And its built-in thermal and overcurrent protection ensure the safety and longevity of the system. The FBX2 is a great choice for protecting circuits from high currents and overloads.
