Circuit Breakers are electrical switches that can be opened or closed depending on the current flowing through the circuit. In order to protect the circuit from fault, overload, and surge current, a switch is used to interrupt the circuit. 992218 is a Circuit Breaker that has evolved to meet the requirements of the modern society. It is unique compared to other circuit breakers due to its reliable temperature compensated arc chute technology.

Applications of 992218

The 992218 Circuit Breaker has numerous applications due to its innovative design. It is used primarily in medium voltage distribution circuits, but it can also be found in industrial applications. It is also often used in remote switching applications, such as remote control of Street Lights. The 992218 main contact block is designed in such a way that it can easily adapt to different configurations of circuit breaker blocks. This allows for easy engineering changes or modifications to the circuit.

Features of 992218

The 992218 Circuit Breaker has numerous features that make it an excellent electrical switch for many applications. It has a one-piece frame and handle, so it can withstand high levels of shock and vibration. The handle can also be locked in open and closed positions with a unique simple latch. The 992218 offers overload and thermal protection, due to the internal phase-time delay relay. This relay senses both motor current overload and temperature, cutting the power when either criterion is exceeded. It also has a wide range of ratings, from 12-38 Amps at 480 volts (V) and 24-46 Amps at 600 V.

Working Principle of 992218

The 992218 Circuit Breaker relies on several mechanisms to protect the circuit from fault, overload, and surge current. The main contact employs Positive-Make-Break (PMB) technology, where electrical current flows through the contacts when closed and when opened, the contact opens cleanly, away from the contacts. This ensures that no contact welding occurs and no arcing occurs, which can cause damage to the contacts. The breaker also relies on a unique temperature compensated arc chute technology. This technology limits the amount of arcing during an electrical fault and ensures that the breaker can safely and quickly clear the fault from the system.

The 992218 also uses an arc flash monitoring system. This system measures the temperature of the arc and cuts the power if it exceeds a certain temperature. This prevents the arc from becoming too hot, which can cause permanent damage to the electrical system. The breaker is also protected from high fault currents by its over-current protection device, which operates on two levels. The first level is thermal protection, which cuts off the power if the current exceeds a certain level. The second level is motor overload protection, which cuts off the power if the motor is overloaded.

Conclusion

The 992218 Circuit Breaker has numerous features that make it an excellent electrical switch for many applications. With its one-piece frame and handle, as well as its overload and thermal protection, the 992218 is an ideal choice for medium voltage distribution circuits and industrial applications. Furthermore, its temperature compensated arc chute technology and arc flash monitoring system make it the perfect choice for remote switching applications. With these features and more, the 992218 is an unbeatable choice for any circuit breaker need.
