• Overall ratings from 400A to 2000A
• Enclosures fabricated from 316L stainless steel
• Ingress protection to IP56
• Form 4 segregation for bus bars and hard wired circuits
• Access to to termination compartments controlled by electrical or mechanical interlock.
• Use of modular RCDs with variable sensitivity, time delay and test sockets to protect higher current circuits.
• Monitored earth protection with over ride option for high current circuits.
• Doors fitted with upper and lower stays, due to high winds in exposed locations.
• Controlled access to socket outlets, to eliminate unauthorised interference with plug-in connections.
• Brushed strip protection to socket compartments to minimise foreign body ingress.
• Co-ordinated short circuit protection enabling the use of MCBs and RCCBs in locations with a high PSCC.
• Phase supply indicators for the incoming supply and for the main bus bars.
• Anti-condensation heaters with thermostat and manual control.
