Circuit breakers are very important safety devices that protect electrical circuits from damage caused by overloads. The J7MN-3R-2E5 circuit breaker is a three-pole thermal-magnetic circuit breaker designed for use in low voltage applications. It provides protection against overloads and short circuits, and is suitable for UL, IEC, CSA, and CE applications.

The Working Principle

The J7MN-3R-2E5 circuit breaker is a thermal-magnetic breaker, which means it has two different types of operating mechanisms. The first type is a thermal mechanism, which senses the heat produced by an overloaded circuit and trips the breaker in the event of a dangerous surge. The second type is a magnetic mechanism, which uses a magnetic field sensing circuit to detect short-circuit current and trips the breaker if a dangerous level of current is detected.

The J7MN-3R-2E5 circuit breaker offers adjustable overload current ratings, from 6 to 25A. This enables users to choose the ideal setting to protect the specific application. The adjustable overload current ratings also allows the J7MN-3R-2E5 circuit breaker to be used in a wide variety of applications, from residential and commercial to industrial.

The Application Field

The J7MN-3R-2E5 circuit breaker is an ideal solution for a variety of low-voltage applications, such as residential, commercial, industrial, and military. It can be used in systems with a voltage range from 2.5 to 250V AC, and can be mounted in both circuit compartments and enclosed boxes.

It is also suitable for use in hazardous areas, and is compliant with UL 489, UL 508, and UL 943 safety standards. This makes it an ideal choice for applications such as motor control, UPS systems, and emergency lighting.

The J7MN-3R-2E5 circuit breaker can also be used in motor winding protection. It is designed to detect winding faults and prevent them from causing more extensive motor damage, and is ideal for use in safety-critical applications.

The J7MN-3R-2E5 is also suitable for renewable energy applications, such as solar panels and wind turbines. It can be used to protect electrical systems from overvoltage and short-circuit current, ensuring that power sources are not damaged.

Conclusion

The J7MN-3R-2E5 circuit breaker is a reliable and safe device found in a variety of low-voltage applications. It offers adjustable overload current ratings, is compliant with UL safety standards, and is suitable for hazardous areas. It is an ideal solution for motor winding protection, emergency lighting, and renewable energy applications.
