Grounding resistance exceeds the limit alarm
Zero ground voltage overlimit alarmReal-time monitoring ground resistance, accuracy 0.5Ω, resolution 0.1Ω
Real-time monitoring of voltage between neutral line and wire
Monitor 220VAC input voltage status, over and under voltage alarm
36mm width, standard rail mounting
