| Current : | 100A |
The OBCH OBS7-6-VA/1P+N is a DIN-rail mounted voltage and current protector available in 80A and 100A heavy-duty ratings. Designed for single-phase systems, it supports a wide voltage range of 80–300V, making it ideal for unstable power grids worldwide.
This adjustable voltage protector features a dual digital display showing real-time voltage and load current. Front-panel buttons allow users to customize over-voltage, under-voltage, and delay reclosing thresholds. As an auto-reset voltage protector, it automatically reconnects power once grid voltage normalizes, delivering 3-in-1 protection against over-voltage, under-voltage, and overload.
Key Features:
Dual digital display – Red and green screens simultaneously show voltage and current for real-time monitoring.
80–300V ultra-wide voltage range – Delivers stable protection in fluctuating grid environments worldwide.
80A / 100A high current capacity – Handles heavy loads for residential and commercial applications.
Adjustable parameters – Four buttons allow customized over-voltage, under-voltage, and reclosure delay settings.
Auto-reclosing function – Power restores automatically when voltage stabilizes – no manual reset needed.
DIN-rail mounting – Modular snap-on design for quick installation in distribution panels.
3-in-1 protection – Integrated over-voltage, under-voltage, and overload limiting to safeguard appliances.
