At a Glance
A see-through solution for three-wire metering circuits, this transparent junction box pairs a full-length 188 mm body with a clear shell, so terminal condition and wiring can be inspected instantly. It is sized for three-phase three-line metering with two CTs and fully supports live changeover and on-site verification.
Recommended Applications
Meter panels where wiring must be visible for routine checks
Three-line circuits for industrial and commercial metering points
Replacement of old opaque terminal blocks with transparent versions
Advantages
Clear shell shows every connection without opening the cover
Red separation markers help installers tell phases apart quickly
Stable contact terminals stay secure under repeated testing
Long body leaves generous room for tidy three-wire routing
