Circuit Breakers

A circuit breaker is an electrical protection device designed to disconnect the electrical circuit automatically when there is an overload or short-circuit. Circuit breakers provide protection against overloads in the system, by preventing an excessive current flow, they also limit short circuit currents and allow service personnel to safely disconnect the system. The BR3D16UC is a circuit breaker designed for use in industrial and commercial applications.

Application Field and Working Principle of BR3D16UC Circuit Breaker

The BR3D16UC circuit breaker is designed to protect single- and three-phase motor loads in industrial and commercial applications against both overload and short circuit conditions. The BR3D16UC breaker is rated for up to 16 Amps and is UL listed for use in 110V AC and 240V AC applications.

The circuit breaker works by sensing the current in the circuit and comparing it to the rated current. When the rated current is exceeded, the circuit breaker trips and automatically disconnects the circuit. When this happens, the handle of the breaker will snap to the OFF position, cutting off the power to the circuit. There is also a Test/Reset button that will reset the circuit breaker if it has tripped. If the breaker will not reset, then there is likely an issue with the wiring or a fault in the circuit that must be corrected in order to reset the breaker.

The BR3D16UC circuit breaker is designed with several safety features to ensure it operates as expected and does not trip unnecessarily. The unit is rated and tested to UL 489 standards, ensuring it meets the industry standards for safety and reliability. It also features an auxiliary switch for automatic disconnection, dual indicators to show if tripped, plus an adjustable trip sensitivity in both overload and short-circuit settings.

The BR3D16UC circuit breaker also features a quick-make/quick-break operating mechanism, making it easier to engage and disengage the contacts. This is important in applications where the circuit must be switched regularly or in applications dealing with high levels of surge voltage. In addition, the BR3D16UC has a double-pole design, meaning that each pole can act as a single-pole breaker, protecting two different circuits or one split-phase circuit.

The BR3D16UC circuit breaker is a reliable and robust solution for protecting electrical circuits in industrial and commercial applications. Its high performance ratings, as well as its adjustable trip sensitivity and reliable operation, make it an ideal choice for applications of all types. It is a compact and low-cost solution for many of today’s applications, making it a great choice for protecting electrical circuits in various environments.
