Circuit Breakers are utilized in any electrical system, regardless of size, to protect from the potentially catastrophic effects of a short circuit or overload. A circuit breaker is an automatic switching device that is designed to open and close a circuit under normal or abnormal conditions to protect electrical components from excessive current or voltage which may cause damage and/or fires. The JLE-3-37073-1 is a type of Circuit Breaker generally known as a Molded Case Circuit Breaker (MCCB), used as a method to interrupt or trip the circuit in the event of an overload or fault current.

The JLE-3-37073-1 is designed as a single phase, three pole, adjustable trip circuit breaker. It has an adjustable trip range of 70-1999 amps, and is rated for a maximum sustained current of 5000 amps. The breaker is designed to operate in a very short time, generally between 12 and 30 milliseconds depending on the fault condition. The breaker has two different tripping mechanisms. The Thermal Magnetic mechanism utilizes a combination of thermal and magnetic forces to trip the breaker when the temperature of the circuit becomes too high due to the over current. The Electronic Trip mechanism utilizes an electronic device that is triggered when a predetermined amount of current is detected. The electronic trips can be adjusted to adjust the breaker’s response time to the fault conditions.

The JLE-3-37073-1 is generally used in industrial and commercial installations to protect and isolate the electrical system from overloads or short circuits, as well as provide an indication in the event of such an occurrence. The breaker also provides an adjustable means to limit the amount of power that can be drawn from a particular source. The adjustable trip settings allow the user to ensure the safety of a particular circuit by limiting the amount of current that can flow through it. An additional safety feature is the breaker’s built-in ability to detect ground faults, helping to reduce the risk of electric shocks or fires.

The JLE-3-37073-1 is capable of being both manually and remotely operated, making it an ideal solution for controlling multiple circuits from one location. The manual trips are accessible via the breaker’s built-in handle, while the electronic trips are available from a number of remote points, depending on the type of installation. The breaker can also be equipped with a variety of accessories, including auxiliary contacts, signaling contacts, alarm contacts, and undervoltage releases.

In conclusion, the JLE-3-37073-1 is a highly versatile and reliable circuit breaker designed to provide a durable, cost-effective solution for the protection of electrical systems and components. Its adjustable tripping settings, coupled with the ability to operate remotely, make it a great option for a variety of applications.
