Smart Volt-Amp Protection Relay

VAP-63/3PN

1. General Description

The iLEC VAP-63/3PN is an advanced 3-phase 63A automatic voltage and current protection relay designed to effectively protect electrical equipment, machinery, control cabinets, and power distribution systems from hazardous electrical system failures. It features comprehensive protection and automatic power cut-off to isolate faults, followed by an automatic reconnection (auto-reclose) function once power parameters return to safe levels. With its compact design and professional features, this device is perfectly suited for installation in residential, commercial, and industrial electrical panels.

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.
