A circuit breaker is a device that opens and closes a circuit in response to a detected overload or short circuit. The IELHK111-1-61-70.0-K-01-V circuit breaker is one of the most popular choices for industrial, commercial and residential power systems. It is rated for up to 70 amperes. It also has a high voltage rating, making it suitable for high-power applications.

This circuit breaker is manufactured in accordance with UL 489 and CSA C22.2 No. 5-11 standards. It features a UL listed draw-out latch mechanism to disconnect the current from the load in an emergency situation. The circuit breaker comes with a manual reset switch, a digital delay timer and two auxiliary contacts. The auxiliary contacts can be used to control an alarm or signal system.

The IELHK111-1-61-70.0-K-01-V circuit breaker is mainly used in commercial, industrial and residential applications where a controlled disconnection of current is required. It is used to prevent electrical overloads and short circuits. It can be used to protect electrical circuits from damage caused by excessive current. It can also be used to control circuits for lighting and motor controls.

The working principle of the circuit breaker is based on the rapid heating of a bimetallic strip when an overcurrent passes through it. A bimetallic strip is a rectangular metal strip composed of two strips of two different metals. When the current passes through it, the different metals expand at different rates due to their different expansion coefficients. This expansion causes the strip to bend, which somehow trips a switch inside the circuit breaker.

Once the circuit breaker is tripped, the switch is open and the circuit is disconnected. The switch can be reset manually by pressing the reset button. This manually closes the switch, restoring the power to the circuit. The digital delay timer acts as a safety feature to prevent the circuit breaker from being turned back on too quickly.

The IELHK111-1-61-70.0-K-01-V circuit breaker is a reliable, versatile and cost-effective protection device for high-power applications. It is easy to install and comes with a comprehensive manual. It has a robust construction and is designed to last for many years. It is the ideal choice for a wide range of commercial, industrial and residential power applications.
