VOLTAGE AND CURRENT PROTECTION RELAY
Model VAP-63/3PN
| iLEC VAP-63/3PN is a voltage and current protection device for 3P+N 63A system, designed to monitor and protect against overvoltage, undervoltage, overcurrent, phase loss, and phase imbalance conditions. It features automatic switching and automatic recovery after faults. |  |
Features
- Overvoltage, undervoltage, overcurrent, phase loss, and phase imbalance protection to help prevent electrical system failures.
- Compact design with flame-retardant engineering plastic housing, providing excellent insulation and heat resistance.
- DIN rail mounting module, suitable for residential, commercial, and industrial electrical panels.
- LED display for clear real-time monitoring of voltage, current, and operating status.
- Adjustable voltage, current protection thresholds, and recovery delay time.
- Parameters can be easily configured via front-panel function buttons.
- Screw-type terminals ensure fast, secure, and safe wiring connections.
- High-durability conductive alloy relay contacts for stable operation.
- Automatic power cut-off and automatic reconnection when voltage and current return to normal conditions.
- Effectively protects electrical equipment, machinery, control cabinets, and power distribution systems.
Product Characteristics
- Microcontroller-based design for stable and reliable operation.
- Synchronous (SYN) and Asynchronous (ASY) operating modes.
- Voltage measurement accuracy: ±1%.
- 6-module DIN rail mounting design.
Front-Face Panel
Reset/start delay display:
Voltage operating values display on L1-L2-L3 and current. The current is displayed on the second row, they will be normally ON after the display is over and the output relay closes.
Indication for incorrect phase sequence:
Display L1-L3-L2 when phase failure fault occurs. User can change the position of L2 and L3 after disconnected supply.
Indication of continuous over current faults:
Display for continuous over current faults after reset/start delay is over. Over current faults times is more than preset times. Disconnect the overload device. Start the relay after reset manually.

Operating Instructions
▪ Voltage Fault Detection
If a voltage fault is detected during the relay reset/start delay countdown, the output relay will disconnect and the fault indication LED will light up.
▪ Normal Operation
During normal operation, the display shows real-time voltage and current values. If a voltage or current fault is detected, the output relay disconnects and the fault indication LEDs light up.
▪ Voltage Fault Recovery
When the input voltage returns to the hysteresis threshold (Hys) after a voltage fault trip, the relay resets automatically.
During the reset/start delay countdown, the fault indication LEDs turn off and the operating voltage and current values flash on the display.
▪ Current Fault Recovery
After the relay trips due to an overcurrent fault, it resets automatically.
During the reset/start delay countdown, the fault indication LED turns off and the operating voltage and current values flash on the display.
