Circuit breakers are integral components of electrical systems used to interrupt and connect an electrical conductor and protect wiring and components from damage due to excessive current. JLE-3-37073-2 is an example of a circuit breaker from Siemens. It is used in applications that require reliable protection from overcurrent and short circuit. In this article, we will discuss the application field and working principle of the JLE-3-37073-2 circuit breaker.

The JLE-3-37073-2 is a two-pole circuit breaker rated for a maximum current of 220 amperes and a maximum voltage of 7700 volts.It is UL, cUL, CE, and IEC compliant for safety and reliability. It is used in switchgear and panelboards that require the highest level of overcurrent protection. It can be used in substations, industrial installations, residential and commercial buildings, and in any other application where a reliable circuit breaker is needed. It is most commonly used to protect wiring and components from damage due to a short circuit or an overload.

The working principle of the JLE-3-37073-2 is based on electromechanical operation. When an overload or short circuit occurs, the circuit breaker’s built-in heat-sensitive element detects the surge of heat and current and triggers the trip mechanism. The breaker opens and cuts off the power to the circuit, thereby protecting the wiring and components from damage. The JLE-3-37073-2 also offers various other features such as automatic reset, surge protection, current limiting, and protection against system disturbances.

The JLE-3-37073-2 is an excellent choice for applications that require reliable protection from short circuits and overloads. It is easy to install and maintain, and it offers reliable protection in any application. With its UL, cUL, CE, and IEC compliance, the JLE-3-37073-2 is an ideal choice for any application.
