Circuit Breakers

Introduction

Circuit Breakers are important components within most electrical systems, providing key protection from electrical overload and short-circuits. Circuit breakers are designed to protect against the effects of electrical overloading and short-circuiting on machinery, lines, and personnel. When an over-current or overload flows through the circuit, a tripswitch within the breaker activates and the breaker trips, cutting off the safety system so that the electrical system can be shut down. In this article, we will look at the application field and working principle of the UPL111-1REC2-3307-2 Circuit Breaker.

Application Field

The UPL111-1REC2-3307-2 is a three-pole negative contact type circuit breaker with a shunt trip and fusible contact. It is designed for use in light commercial applications and is rated for up to 120/240 volts with a maximum of 40 amperes. It is suitable for compact spaces, such as load centers, panel boards, lighting control systems, and service entrance panels. The UPL111-1REC2-3307-2 circuit breaker is also designed with a black baked enamel finish, making it resistant to harsh elements and corrosion, and is UL listed for use in light commercial or open industrial environments.

Working Principle

The UPL111-1REC2-3307-2 circuit breaker works on the principle of a trip switch. When the circuit over-currents, the trip switch within the panel-board breaker trips, cutting off the safety system and shutting off the electrical system. The UPL111-1REC2-3307-2 circuit breaker has three operating stages designed to protect different components of the electrical system. The first stage is a thermal overload stage, which trips if an over-current is present in the system. This stage is designed to protect the motors within the machinery. The second stage is a motor protection stage which trips if it detects a short-circuit. This stage is designed to protect the wiring and other components used in the electrical system. The third stage is the trip switch stage, which trips with an extreme overload or short-circuit to protect the circuit. This stage is designed to protect the electrical system and personnel from any damage that could occur due to the overload or short-circuit.

Conclusion

The UPL111-1REC2-3307-2 circuit breaker is an essential component of any electrical system. It is designed to provide protection against electrical overloads and short-circuits, safeguarding personnel and equipment from serious damage. The working principle of the UPL111-1REC2-3307-2 is based on the core principle of a trip switch, which cuts off the electrical system if an extreme overload or short-circuit is detected. The UPL111-1REC2-3307-2 offers a low cost, reliable solution for light commercial applications. Its durable construction and UL listing make it the perfect choice for any commercial or industrial setting.
