The TY-SY3W-Z08 residual current electrical fire monitoring detector is a highly sensitive smart electrical fire monitoring detector (hereinafter referred to as the monitoring detector) to monitor eight ways of residual current (compliant with GB14287.2-2014). With built-in high-performance MCU, the detector features reliable performance, powerful function, flexible installation, and simple operation. In addition to effective cost reduction, the monitoring detector uses fully digital processing technology to effectively avoid missed and false alarms.

? The monitoring detector is designed to feature good applicability, stable and reliable performance, low false alarm rate, and flexible and convenient installation. In addition, one monitor can monitor up to 8 residual current transformers.
? It is especially suitable for an electrical fire monitoring system monitoring multiple ways of residual current simultaneously. Users no longer need to select multiple monitoring detectors, effectively reducing the operating cost of the system.
