Circuit breakers are essential pieces of protective equipment used in electrical systems. Without them, an overload of current could cause an emergency system failure. The APGN6-87060-LL Circuit Breaker can be used to address these issues in an efficient and cost-effective manner. This article will provide an overview of its application field and working principle.

Application Field

The APGN6-87060-LL is a thermal-magnetic type Circuit Breaker that provides overload and short circuit protection for AC systems with a rated operating voltage of up to 690V, and a nominal current up to 63A. Its vapor-proof enclosure ensures safety and fast response in the case of high-current overloads. This type of breaker can be integrated into a range of applications, including machine tools, lighting, HVAC, control systems, and in distribution systems.

Working Principle

APGN6-87060-LL Circuit Breakers combine two protection elements – magnetism and heat which both work on the same sequence. When a fault occurs, the magnetism element trips the mechanism immediately as the current exceeds its rating. The heat element then kicks in a few milliseconds later, providing additional protection by tripping the breaker at a higher current level. This means the APGN6-87060-LL Circuit Breakers can detect small overloads before they become a more serious problem.

The thermal-magnetic operating principle also ensures the breaker’s longevity, as the heat element does not wear out from continuous or pulsed overloads. This type of breaker can be used in both AC and DC circuits, and has an endurance rating of 10,000 cycles.

Conclusion

The APGN6-87060-LL Circuit Breaker is a cost-effective breaker that offers reliable overload and short circuit protection for AC systems with a rated operating voltage of up to 690V, and a nominal current up to 63A. Its thermal-magnetic operating principle ensures durability, and its vapor-proof enclosure makes it suitable for harsh environments. It can be used in a variety of applications, including machine tools, lighting, HVAC, control systems, and in distribution systems.
