16A 5-pin CEE diagnostic plug with built-in LED indicators for testing three-phase industrial power. It reads rotating field direction, phase presence, neutral and earth continuity in real time, the quick check that catches a reversed rotation before it damages a hoist or a motor. Operates at 400V, 50–60Hz.

Tests
A diagnostic plug is a check, not a substitute for testingIt confirms rotation and continuity at the socket. It does not replace a proper installation test, and it will not detect a high-resistance earth. Treat it as the fast pre-use check it is.
