Product Details
LV Distribution Panelboard TUR8-1200 panelboard ACG wiring
TUR LV distribution panelboard is used to protect and control low-voltage (LV) distribution networks in medium-voltage/low-voltage (MV/LV) substations. It's installed right after the 630kVA transformer.
LV Distribution Panelboard comes with a four-pole LV load break switch that has a visible break point. LV Distribution Panelboard also features interchangeable 400A outgoing feeders with a distributed neutral system. Each of these feeders is fitted with three voltage-operable fuses, plus a rotary link that lets you disconnect the neutral wire when needed.
◎Easily supply the electric power with a small-scale and adjustable configuration (up to 4, 5 or 8 outgoing feeders),
◎Isolate the low voltage by switch disconnector (power up to 1000kVA).
◎Protect by HPC fuses the outgoing feeders.
TUR panelboards comprise:
• A four-phases load break switch-disconnector with a visible opening: 800 A, 1200 A or 1800 A.
• Low-voltage outgoing feeders are fully interchangeable, fitted with three load-operable fuses rated up to 400A. Easily cut off the neutral line using the built-in rotary lever.
• Optional:
- Public lighting protection device (ACG).
- Station lighting protection device (EP).
- Reservation panels (to avoid active parts touching when no outgoing feeder is mounted on the panelboard).
- Lock panels (to condemn an outgoing feeder when fuses are removed)
