About this item

• 1. ADVANCED 3-PHASE VOLTAGE & OVER CURRENT PROTECTION The Leyden LE-VAPTP 63A is designed to monitor and protect three-phase electrical systems against abnormal voltage and excessive current conditions. It provides adjustable under-voltage, over-voltage and over-current/overload protection, helping protect connected equipment from potentially damaging electrical conditions.
• 2. WIDE ADJUSTABLE PROTECTION RANGE Configure the protection parameters according to your application requirements. Under-Voltage / Phase Protection: 80–210V, Over-Voltage Protection: 130–300V, and Over-Current Protection: 1–63A. This adjustable design makes the device suitable for a wide range of three-phase electrical applications.
• 3. ADJUSTABLE POWER-ON & PROTECTION RECOVERY DELAY The device features an adjustable Power-On Delay Timer from 1–999 seconds and Protection Recovery Delay Timer from 1–999 seconds. These adjustable timers help manage equipment startup and allow a suitable recovery period after an abnormal voltage or current condition has been cleared.
• 4. SYNCHRONOUS & ASYNCHRONOUS MODES WITH PHASE SEQUENCE PROTECTION Select Synchronous Mode or Asynchronous Mode according to your system requirements. The device also provides Phase Sequence Protection to help identify incorrect three-phase phase rotation conditions, making it suitable for phase-sensitive equipment such as motors and pumps.
• 5. PASSWORD PROTECTION & DIGITAL MONITORING Password protection helps prevent unauthorized changes to configured protection parameters. The digital display provides convenient monitoring of the three-phase electrical system and helps users identify protection status and abnormal conditions.
