4. Варијанти на производи

The TOVPD3 series is available in several configurations to suit different electrical systems. The primary differences lie in the current rating and the presence of a neutral (N) connection, which affects the voltage display and wiring:

• 63A With N (3X120V/3X220V/3X230V): Designed for 3-phase systems with a neutral line. Each phase voltage (L1, L2, L3) is displayed relative to the neutral. For example, in a 3*220V+N system, each phase will display 220V.
• 63A without N (380V): Designed for 3-phase systems without a neutral line. The device displays the line-to-line voltage for each phase (e.g., L1-L2, L2-L3, L3-L1), typically showing 380V across all phases.
• 100A With N (3X220V): Similar to the 63A With N variant but with a higher current capacity.
• 100A without N (380V): Similar to the 63A without N variant but with a higher current capacity.

Ensure you select the correct variant for your specific electrical installation.

6. Инсталација

6.1 Монтирање

The TOMZN TOVPD3-63VA is designed for Din Rail mounting. Ensure the Din Rail is securely installed in an appropriate electrical enclosure, away from moisture and excessive heat.

6.2 Wици

IMPORTANT: Disconnect all power before proceeding with wiring.

1. Identify the input (IN) and output (OUT) terminals on the device. The terminals are typically labeled L1, L2, L3, and N (if applicable).
2. Connect the incoming three-phase power supply to the 'IN' terminals (L1, L2, L3). If your model includes a neutral connection, connect the neutral line to the 'N' terminal.
3. Connect the load (equipment to be protected) to the 'OUT' terminals (L1, L2, L3). If your model includes a neutral connection, connect the load's neutral line to the 'N' output terminal.
4. Ensure all connections are tight and secure to prevent loose contacts, which can cause overheating or malfunction.
5. Double-check all wiring against your system's electrical diagram and local codes before restoring power.
