Circuit Breakers

Circuit breakers are a type of electrical protection device that are used to prevent short circuits and protect against electrical faults. They are designed to operate automatically when an overload or short circuit occurs, by interrupting the electrical flow. Circuit breakers can be used in a variety of applications to protect a variety of different circuits, ranging from industrial machinery to home electrical systems. In this article, we will discuss the 209-1-1-51-2-8-10 Circuit Breaker, its application field and working principle.

209-1-1-51-2-8-10 Circuit Breaker Features

The 209-1-1-51-2-8-10 Circuit Breaker is a two-pole, three-line, 30A unit with a thermally-sensitive tripping mechanism. It is most commonly used in residential, commercial and industrial applications. Its features include:

• UL Recognized
• Meets UL, CSA, IEC and other safety requirements
• High Interrupting Capacity (HIC)
• Switch Ratings: AC/DC 20A, 120/250V
• Contact Form: DPST (double-pole, single-throw)

Application Field

The 209-1-1-51-2-8-10 Circuit Breaker is designed for use in a variety of applications. It is most commonly used in residential circuit breaker panels, industrial control panels, and distribution/motor control panels. It can be used as a main line disconnect, a lighting disconnect, or a circuit protection device in a breaker panel to protect circuits from overloads or short circuits.

Working Principle

The 209-1-1-51-2-8-10 Circuit Breaker is a thermal-magnetic circuit breaker. It is an electronic device that uses a combination of thermal and magnetic forces to protect a circuit from overcurrents and short circuits. When an overcurrent occurs, the heater coil inside the breaker heats up and expands, which causes a mechanical movement that trips a release switch. Once the switch is tripped, the breaker trips and disconnects the power supply from the circuit.

The 209-1-1-51-2-8-10 Circuit Breaker also has a magnetic trip feature. If a short circuit or an overcurrent occurs, the movement of the current causes a magnetic field to be generated. This magnetic field acts as an overload protection and trips the breaker without having to wait for the thermal element to react and heat up. This is sometimes referred to as "magnetic only" protection.

Conclusion

The 209-1-1-51-2-8-10 Circuit Breaker is a two-pole, three-line, 30A unit with a thermally-sensitive tripping mechanism. It is most commonly used in residential, commercial, and industrial applications. It can be used as a main line disconnect, a lighting disconnect, or a circuit protection device in a breaker panel to protect circuits from overloads or short circuits. The 209-1-1-51-2-8-10 Circuit Breaker uses a combination of thermal and magnetic forces to protect a circuit from overcurrents and short circuits.It has a high interrupting capacity, meets all UL, CSA, IEC and other safety requirements, and has a contact form of DPST (double-pole, single-throw).
