The CNC YCBZ-63 4P 50A is a robust manual changeover switch designed to transfer power between two sources—typically grid and generator—in three-phase systems. It functions as a switch disconnector, capable of switching on, loading, and breaking circuits under normal operating conditions.
Rated at 50A and 230/400V~, this 4-pole configuration ensures safe and complete disconnection across all phases and neutral. It features a 1-0-2 contact form for clear source selection and mounts easily on a DIN rail EN60715 (35mm) using a fast clip system.
The YCBZ-63 series is available in 1P, 2P, 3P, and 4P versions and includes overload and short-circuit protection. It complies with IEC/EN60947-3, making it ideal for residential, commercial, and industrial environments requiring manual power transfer and system continuity.
