What is Blue Jay Arc Guard?
Blue Jay Electrical Arc Guards are comprehensive arc protection solutions. They detect current and arc flash simultaneously and then send arc fault or current signals to the circuit breaker. The arc-flash mitigation strategies include Light-Sensing Only, Light Flash Supervised by Current, and Light Flash Supervised by Pressure(Optional). Take our AFR-3S Arc guard relay as an example, it is mainly used to detect arc faults in electrical systems and protect switchgear from arc faults. The arc guard system can detect arc flash by monitoring current or light, and quickly disconnect the power supply before an electrical fire occurs.
What Is ABB Arc Guard?
ABB Arc Guard is an optical arc flash mitigation device. It can detect arc flash and send the signal to the circuit breaker. How does the ABB Arc Guard system work? Firstly, detect light from an arc flash. Secondly, recognize whether it is an arc fault and not another light source. Finally, send signals to trip breakers.
