GST18 Compact Connector The GST18 is a pluggable device connector for use in lighting and other factory-assembled equipment. Mechanical and color coding provides for a safe and easy separation of different applications, virtually eliminating mis-mating errors. An IP20 touch-safe design, a leading earth contact and an optional locking device all contribute to ensure the safest possible connections. This connector would suit the AC OUTPUT of most small Victron Multiplus units and some Phoenix Inverters.
