The 50A slip ring collectors have 50A line rings (maximum 16 rings) and they are supplied either with or without protection.
The protection has small downward holes to allow air circulation and the lower support plate is provided with three holes to drain the moisture which may form inside the unit.
All slip ring collectors are tested to operate at a maximum ambient temperature ranging from -25°C to +70°C. Slip ring collectors have a shock-resistant thermoplastic protection to prevent accidental contacts with live parts. They are fitted with phosphor bronze or graphite brushes.
All the materials and components used are weather resistant.
