Circuit Breakers

APGN66-1REC3-7026-3 circuit breakers are units designed to protect electrical circuits from potential hazards due to overload and short circuits. The design of these breakers follows a standard performance-safety model, making them suitable for use in a variety of applications in commercial, industrial, and residential wiring. This article will discuss the application field and working principle of the APGN66-1REC3-7026-3 circuit breaker.

Application Field

The APGN66-1REC3-7026-3 circuit breaker is suitable for use in single-phase and three-phase circuits with current ratings from 10 to 63 amps. Additionally, the breaker is available with various contact positions and tripping conditions for increased flexibility. This makes the unit ideal for a variety of applications in both residential and commercial circuits, including lighting, heating, air conditioning, refrigeration, motor control, and other industrial applications.

The breaker is also ideal for panel board applications due to its small size and slim design, making it easy to mount in tight spaces. The unit is UL 489 listed and has been tested to meet various CSA and UL requirements, so it can be used with confidence in a wide variety of applications.

Working Principle

The APGN66-1REC3-7026-3 circuit breaker works by reacting to fluctuations in current draw and providing automatic overcurrent protection. This is done by using a bimetallic strip, which bends when exposed to heat generated by an increased current draw in the circuit. When this happens, the strip triggers the circuit breaker, temporarily opening the circuit and preventing an overload or short circuit from occurring.

The bimetallic strip allows the breaker to respond quickly to deviations in current and prevents the possibility of delaying relay action, which could result in a potentially hazardous situation. Additionally, the unit is capable of resetting itself automatically after the current in the circuit has returned to normal, allowing the circuit to continue functioning without any further intervention.

Conclusion

The APGN66-1REC3-7026-3 circuit breaker is designed to provide reliable overcurrent protection in single-phase and three-phase circuits. Its small size and slim design make it ideal for use in panel boards, while its UL 489 listing and UL and CSA testing ensures its high-quality performance. Finally, its bimetallic strip reacts quickly to current fluctuations, providing fast protection against overload and short circuit hazards.
