Panel Builders

PANEL BUILDERS,

CONSULTANTS AND

CLIENT/END USERS

Recommend rear access of 800mm with a minimum of 600mm for completely isolated panels.
- Operational front access of 1200mm
- All panels are supplied with the option of extension on either end.
- All shipped sections can be moved / rigged with standard 2,5T forklift.
- Merlin Arc Pressure Valve (MAPV) requirement to be advised at time of quote / order.
- Standard heavy-duty base of 3mm mild steel welded construction and powder coated black.
- Frame, covers and chassis plates made of Aluzinc, giving good bonding properties with powder coating optional.
- Gland plates of 2,5mm galvanized plates as standard, 3mm galvanized and 5mm aluminium is optional.
- Doors and covers standard colours: light grey or orange. Additional colour options available.
- We recommend using ACB’s for main incoming and any outgoing circuit of 800A, 1000A, 1250A, 1600A, 2000A, 2500A and 3200A.
- IP3X recommended for internal panels as higher IP ratings cause switchgear components to operate at higher temperatures thus reducing the service life.
