Selection Notes

The LV848535 has no reset function, so the 5-digit count is a permanent maintenance record of total operations rather than a figure that can be zeroed after service; track remaining mechanical life against the breaker's rated endurance using this count. It is purely mechanical, with no electrical output for remote monitoring — pair it with the EIFE Ethernet module if operation count needs to be read remotely. It fits both fixed and drawout MTZ2/MTZ3 breakers. Because the display is mechanical, it continues to show the correct count even with no control power applied to the breaker.
