Sequestr Low-Amp External Disconnect Type 4 12 and 3R
Isolate low-amp disconnect switches and breakers in the Sequestr external disconnect enclosure to mitigate arc flash incidents. Install on free-stand or floor-mount disconnect enclosures to reduce exposure to incoming power. When the disconnect handle is turned OFF, there is no live power on the load side cables passing through to the main enclosure. The Sequestr enclosure is sized for use with up to 200A disconnect switches or up to 400A breakers dependent on NEC 430.10(B), and is designed to fit with bulletins A34, A35, A28, A21 and A4L3D main enclosures. Refer to installation manual for configuration mounting and hole pattern.
