How to Apply Corrosion Protection to MCCs#
- Electrical contacts should be sprayed with ElectriCorr™ VpCI®-239, which dries into a very thin film that protects against aggressive conditions.
- VpCI® emitting devices can also be placed inside MCC components for vapor-phase protection throughout the enclosures according to the space’s volume (VpCI®-101 Devices for 1 ft³ [28 L], VpCI®-105 for 5 ft³ [0.14 m³], and VpCI®-111 for 11 ft³ [0.31 m³]). MCCs the size of an entire room can be protected by adding one VpCI®-308 Pouch per 35 ft³ (1 m³) of internal space.
- MCCs in need of external protection can be wrapped in VpCI®-126 HP UV Shrink Film, which contains contact and vapor-phase inhibitors along with special UV properties for outdoor durability. (If desired, a VpCI®-308 Pouch can be added in between the film and the MCC sides for additional external protection.)
