Circuit breakers are specialised electrical switches designed to protect against overcurrent, overload, short circuits, and ground faults, by automatically disconnecting a circuit when too much current flows through it. The LEGBX66-36225-15-V, manufactured by GE, is a circuit breaker tailored to be used in a range of low voltage applications, from 110V to a maximum of 600V. With a wide range of features and various rated characteristics available, the LEGBX66-36225-15-V is perfect for applications such as security systems, electronic equipment, and process control systems.

In terms of construction, the LEGBX66-36225-15-V features a thermoplastic composite enclosure and two terminals, an operating handle, and an Output slide, for connecting multiple circuits. The LEGBX66-36225-15-V has a switching capacity of 15A, which corresponds to a maximum current rating of 6kA under short circuit conditions. It also features a range of settings that can be adjusted according to the application, including a short delay of up to 120 seconds, adjustable trip curves, and adjustable time delays. Additionally, the LEGBX66-36225-15-V is rated UL1077, ensuring that the design meets the necessary industry standard for safety and reliability.

The working principle of the LEGBX66-36225-15-V is based on the concept of thermal-magnetic protection. This protection occurs in two stages. During the first stage, a thermal-magnetic cut-off switch is activated when the amount of current flowing through the circuit exceeds a predetermined level. This in turn activates a heater, which then generates heat that causes a bimetallic strip to bend, which in turn shuts off the power in the circuit. The second stage is the magnetic cut-off switch, which works by amplifying the current flow through a magnet, which causes a plunger to make contact and shut off the circuit.

The LEGBX66-36225-15-V offers various features that make it suited for all types of applications, from low-cost projects to high-end ones. It is available in either single or multi-pole configurations, allowing users to select the appropriate circuit configuration in order to suit their needs. Additionally, it is designed to operate at temperatures between -211F (-20C) and 149F (65C), making it suitable for use in both indoor and outdoor applications. In addition, its dual-pole and single-pole operation provides greater flexibility in how the device is used and in the type of load it is intended to protect.

In summary, the LEGBX66-36225-15-V circuit breaker is a reliable and safe device, designed for low voltage applications such as security systems, process control systems, and electronic equipment. It has a wide range of settings that can be adjusted to suit the application and is rated UL1077 for safety and reliability. It also features a thermal-magnetic working principle which allows it to effectively protect against overcurrent, overload, short circuits, and ground faults. Lastly, its dual-pole and single-pole operating features provide greater flexibility and make it suited for use in both indoor and outdoor environments.
