Circuit Breakers

W68-X1Q112-20 Application Field and Working Principle

Circuit Breakers are essential components for today’s electrical systems and are used for protecting circuits from over-current overload and ground fault protection. The W68-X1Q112-20 from ABB is a versatile circuit breaker ideal for virtually any low-voltage application including residential, commercial and light industrial applications. This device employs a thermal-magnetic trip unit which utilizes both heat andmagnetic effect to operate.The W68-X1Q112-20 is rated as a Type C-A Short Circuit Current Rating of 10kA, a 480VAC and a maximum operating voltage of 600VAC. This is designed for use with a corresponding main circuit breaker and is UL recognized, CE marked and RoHS compliant. It features a snap-on under voltage release module commonly used to protect motors. This innovative design is suitable for electromechanical, motor protection and single-pole circuit outdoor applications.The W68-X1Q112-20 has a thermal-magnetic trip which utilizes both thermal and magnetic poles to provide reliable, instantaneous short circuit protection. The heater element situated in the bimetal disk heats-up due to continuous current flow and causes the disk to expand. As a result, the engine around the fixed contacts will become deformed, causing them to separate, thus opening the circuit and eliminating the possibility of an electric shock. The magnetic pole of the W68-X1Q112-20 is activated when calibration current is generated and flows through the moving contact. As the current passes through, the magnetic field generates a pressure against a metal link, pushing it and separating the fixed contacts from the moving contacts thus opening the circuit. The reset is performed by turning off the current, allowing the contacts to cool down and close again automatically. In addition to being particularly suitable for motors, the W68-X1Q112-20 also provides excellent motor protection and features a wide range of trip levels from 1.5 to 20X. This feature makes it an ideal choice for applications that require dynamic motor protection in a wide range of power distribution networks. Furthermore, the W68-X1Q112-20 also provides short circuit protection and ground fault protection, and has a compact and lightweight design making it easy to install. Overall, the W68-X1Q112-20 is an incredibly versatile low-voltage circuit breaker suitable for a range of applications including residential, commercial, and light industrial. By utilizing thermal-magnetic trip technology, it provides instantaneous protection against electrical shock and short circuit, while boasting a wide range of trip levels to ensure reliable protection against overloads and short circuits.

Conclusion

The W68-X1Q112-20 is a great choice for circuit protection in virtually any low voltage application. This device utilizes thermal-magnetic trip technology to instantly protect against electrical shocks and short circuits, while also providing excellent motor protection. Furthermore, its wide range of trip levels make it an ideal choice for industrial applications. In addition, this device is also UL recognized, CE marked and RoHS compliant, and has a lightweight and compact design which makes installation quick and easy.
