1D15DL

A circuit breaker is an automatic device designed to prevent an electric circuit from being overloaded or short-circuited. Its main purpose is to protect the electrical system from overload or short circuit, making the entire system safe while it is running. In this article, we will focus on one particular circuit breaker, the 1D15DL and its applicable fields, as well as its working principle.

Application Field

The 1D15DL circuit breaker is mainly used in single-phase alternating current systems. In residential and small business establishments, it can be used to protect circuits from overload, short-circuiting, and ground-fault currents, as well as to isolate electrical loads when necessary. Due to its ability to interrupt large amounts of current, the 1D15DL is also commonly used in the commercial and industrial sectors to protect complex power systems from catastrophic failure.

Working Principle

The 1D15DL circuit breaker consists of a circuit breaker body, a set of contacts, a heat element, and a trip unit. When the circuit breaker is turned on, current passes through the contacts, warming the heat element. If the current increases beyond a certain threshold, the contacts open, cutting off power to the circuit. At the same time, the heat element cools off and causes the trip unit to reclose the contacts, thereby restoring power to the circuit.

The 1D15DL is designed to provide excellent protection against short-circuits and overloads. It features a built-in reset button that allows it to be manually reset after a fault is detected, as well as an LED indicator that lights up when the circuit breaker trips and must be reset. This allows the user to quickly identify and address potential problems before they become dangerous or catastrophic.

Conclusion

The 1D15DL circuit breaker is a reliable and highly effective tool for protecting circuits from overloads, short-circuits, and ground-fault currents. Its simple design and easy reset capabilities make it an ideal choice for residential, commercial, and industrial applications.
