Product Description
3 phase Voltage Protector with auto-reclosing function (automatic voltage protector) takes miniature circuit breaker with short circuit overload protection as the main switch, equipped with the ultra-miniature intelligent electric operation device with the relay, to detect the power supply voltage, and to achieve functions of over-voltage or undervoltage trip protection and automatic recovery circuit after voltage recovery, to ensure safe operation of the load device in the normal voltage range. Theautomatic voltage protectoris integrated OUPA, compared with the ordinary split, it eliminates the wiring troubles, without considering the upper and lower wiring problem, more convenient to install. Integrated OUPA has more compact and comfortable shape, is the best choice for high-end residential sites, mainly applied to the occasion of voltage instability or the device protection that is sensitive to voltage changes.
Automatic voltage protectorsmeet the JGJ242-2011 "Design codes for residential buildings" and "Over-voltage and under-voltage protective device with auto-reclosing function (OUPA) standards." The seriesautomatic voltage protectors have compact size, high breaking capacity, more reliable action, human-computer interaction interface of good performance.
3 phase Voltage Protector Details
1.The overall use integrated design structure, 35mm standard rail to fix, to quickly install, repair or replace for customers;
2. Detect voltage with the relay for opening and closing operation, to protect too low or too high circuit voltage;
3. Fast and reliable opening-closing operation, and the choice of 3 phase miniature circuit breaker platform, high breaking capacity;
4. 2P/1P+N or 4P/3P+N miniature circuit breakers or the corresponding leakage circuit breakers can be chosen;
5. Over-voltage protection, overload and short circuit protection, protection states indication
6. Co-opted function of automatic voltage protector: leakage protection, remote control, fault alarm
