Introduction

A circuit breaker is a device that can protect electrical circuits from overcurrent, overvoltage or overload. The 295-111-1REC2-4851-9 is an advanced type of breaker designed for high performance applications. This article will discuss the application field and working principle of the 295-111-1REC2-4851-9 circuit breaker.

Application Field of 295-111-1REC2-4851-9

The 295-111-1REC2-4851-9 is mainly used for medium voltage electricity distribution in industrial and commercial applications. It has a wide range of features that make it suitable for use in such applications. These features include:•High speed switch and trip-free design which can quickly detect and respond to overcurrents or short circuits.•Highly accurate ratings with independent trip setting which provides high accuracy and safety.•Current limiting protection circuit that prevents overcurrents from damaging electric equipment and wiring.•Automatic reconnection that reduces downtime and maintenance costs.•LED trip indication and LCD display for continuously monitoring and displaying circuit parameters.•Remote alarm and control signals for monitoring and controlling the circuit breaker from a distance.•Low-noise design for quiet operation in tight spaces.All of these features make the 295-111-1REC2-4851-9 a reliable and versatile breaker for any medium voltage distribution application.

Working Principle of 295-111-1REC2-4851-9

The working principle of the 295-111-1REC2-4851-9 circuit breaker revolves around its two main components; the trip coil and the current transformer. The trip coil is used to detect and respond to abnormal currents. It consists of a primary coil and a secondary coil. The primary coil is connected to the breaker, while the secondary coil is connected to an auxiliary switch. When an overload or short circuit occurs, the primary coil produces an electromagnetic field. This field then induces a voltage in the secondary coil, which in turn causes the auxiliary switch to trip the breaker.The current transformer is a type of transformer specifically designed to sense and measure currents. It is composed of a primary coil surrounding a soft iron core, and a secondary coil surrounding the primary coil. When an abnormal current passes through the primary coil, it induces a voltage in the secondary coil, which is then detected by the breaker’s internal circuitry. This voltage is used to trip the breaker in the event of an overcurrent or a short circuit. In summary, the 295-111-1REC2-4851-9 circuit breaker works by monitoring and responding to abnormal currents, either through the trip coil or the current transformer.

Conclusion

By combining advanced features and a reliable working principle, the 295-111-1REC2-4851-9 circuit breaker is an excellent choice for medium voltage distribution applications. Its high speed switch and trip-free design make it able to quickly detect and respond to overcurrents and short circuits. With its current-limiting protection circuit and other features, it provides reliable protection and enables efficient operation.
