The AVP3-63 adjustable voltage and current protector with rated currents of 63A, 80A, and 100A, offering over-voltage, under-voltage, over-current, asymmetry, and phase sequence protection, plus automatic recovery and real-time voltage/current display. It features adjustable settings (voltage, current, time, etc.) and a 100,000-time electro-mechanical life, with 35mm DIN rail installation.
Ideal for protecting industrial motors, CNC machines, air compressors, refrigeration units, pumping stations, and other critical three‑phase equipment against unstable grid conditions, phase loss, phase sequence reversal, and over‑current damage. The built‑in self‑recovery function automatically restores power after fault clearance, eliminating manual reset intervention.
Normal Operating & Installation Conditions
- Ambient temperature: -20°C to +70°C.
- Altitude: ≤ 2000m.
- Relative humidity: ≤ 90% (non‑condensing).
- Pollution degree: 2 (typical for protected indoor environments).
- Installation type: 35mm DIN rail (top‑hat rail).
- Terminal capacity: Suitable for copper conductors — refer to terminal marking for torque and wire size.
