Introduction

A 9912200003 Circuit Breaker is a device used to interrupt an electrical circuit in the event of an overload or short circuit. This type of breaker is used in industrial and commercial environments to protect personnel, as well as, electrical or electronic equipment from harm due to an overload or short circuit current. This article will explain the application field and working principle of the 9912200003 Circuit Breaker.

Application Field

The 9912200003 Circuit Breaker is primarily used in larger scale commercial and industrial applications. This breaker is typically rated at 200 amperes, which makes it well suited for electricity distribution panels and other larger electrical/electronic equipment. It is also commonly used in residential applications, although not as often as other types of breakers. In addition, this breaker is designed to be compatible with the Neutral-Line system, which is used in many countries to meet safety requirements.

Working Principle

The 9912200003 Circuit Breaker operates on the principle of electricity being measured in terms of current flow. When the current flow in a circuit exceeds the normal operating range, the breaker is triggered, protecting both the equipment and personnel in the area. The breaker is designed to open the circuit when the current exceeds the rated amperage, therefore preventing further damage. This type of breaker also has the ability to automatically reset itself after the current has been reduced to a safe level.

The Tripping Mechanism

The 9912200003 Circuit Breaker works using a mechanical tripping mechanism. This mechanism has two main components: the thermal contacts and the bimetallic element. The thermal contacts sense the increase in the current flow and cause the bimetallic element to move. Once the bimetallic element moves, it causes the breaker to trip and open the circuit. This mechanism is designed to quickly and reliably interrupt the current in the event of an overload or short-circuit.

Overload Protection

The 9912200003 Circuit Breaker also provides overload protection. This is accomplished by the use of a time-delay mechanism, which consists of an adjustable screw that can be turned to adjust the tripping time. This allows the breaker to remain closed, even when the current rises above the rated value, until the time-delay has passed. This feature helps to protect against false tripping and premature wear on the breaker.

Conclusion

The 9912200003 Circuit Breaker is a reliable and effective means of providing protection from overloads and short circuits. This type of breaker is commonly used in industrial and commercial applications and is designed to be compatible with the Neutral-Line system. The breaker works using a mechanical tripping mechanism that is triggered by the increase in current, and also provides overload protection with the use of a time-delay mechanism. With proper installation and maintenance, the 9912200003 Circuit Breaker can provide reliable protection for years to come.
