Correct upstream circuit protection and installation by a qualified electrician are required.

Product Title

CNC Electric YCBZ 63A 2-Pole Manual Changeover Switch – 230/400V AC I–0–II

Short Description

The CNC Electric YCBZ 63A 2-pole manual changeover switch provides deliberate I–0–II selection between two AC power sources. The supplied unit is marked 230/400V AC, 50/60Hz and AC-22A, with a linked red operating handle and eight numbered terminals.

Long Description

Designed for controlled manual source selection, the CNC Electric YCBZ 63A changeover switch allows a connected load circuit to be switched between two independent AC supplies. Its three-position I–0–II mechanism provides Source I, centre-off isolation and Source II selection through a linked red two-pole operating handle.

CNC Electric's official YCBZ product page classifies the series as a changeover switch used as a switch-disconnector and states compliance with IEC 60947-3. The official series supports 63A, 80A, 100A and 125A ratings, 1P to 4P configurations, 50/60Hz operation and 1–0–2 contact form. The attached 63A 2P unit is marked 230/400V AC and AC-22A.

The switch is appropriate for professionally designed utility/generator, utility/inverter and other dual-source AC systems requiring manual transfer. It does not automatically detect source failure or transfer the load. Enclosure selection, upstream protection, cable sizing, earthing and installation must follow the applicable electrical code.
