Round ID
Round opening in a compact casing for cables and round conductors.
Overview
Encapsulated Polycarbonate Current Transformers (Nylon Casing)
The encapsulated range pairs a polycarbonate / nylon casing with clip-in secondary terminals, making installation fast and neat. The wide choice of window shapes and terminal positions means you can match the CT to the busbar or cable and to the space available in the panel.
Configurations
6 types to match your installation
Rectangular ID – compact
Compact frame with the primary opening designed to suit smaller busbar and cable sizes.
Rectangular ID – large frame
Large-frame housing for higher-current feeders and heavier conductors.
Shorter Side Terminal
Rectangular window with the secondary terminal on the shorter side – ideal for narrow panel space.
Longer Side Terminal
Wide rectangular window with the terminal on the longer side, suited to wide busbars.
WPL
Compact block-type unit with a solid front face and top-mounted terminals.
