Why Choose the ABB OT63EAUU4CZ 63 A Enclosed Change-Over Switch?
The ABB OT63EAUU4CZ, order number 1SCA139889R1001, is a robust 63 A enclosed change-over switch designed for dependable manual switching between two electrical supplies or circuits. As part of ABB’s metal-enclosed load-break switch range, it combines a 4-pole change-over switching mechanism with a durable steel sheet enclosure for industrial and commercial electrical installations.
The OT63EAUU4CZ provides an I-O-II change-over function, allowing an operator to select either of two circuits with a defined OFF position between them. The supplied black operating handle incorporates cover interlocking and a defeatable interlock function, helping provide controlled and convenient operation during normal use and maintenance.
With an AC-22A and AC-23A rated current of 63 A at 415 V, the OT63EAUU4CZ is suitable for demanding load-transfer applications. The unit includes N and PE terminals and has blank cable entries at both the top and bottom, providing flexibility when preparing the enclosure for the required cable installation.

Reliable Manual Change-Over Switching
Change-over switches provide a controlled method of selecting between two electrical supplies or circuits. The ABB OT63EAUU4CZ uses an I-O-II operating sequence, providing a defined OFF position between the two selectable switching positions and making it suitable for applications requiring deliberate manual source selection.
The enclosed construction combines the switching mechanism, operating handle and protective steel housing into a complete assembly. Its 4-pole configuration enables simultaneous switching of four conductors, while the included neutral and protective earth terminals support straightforward integration into three-phase electrical distribution systems.
Typical Applications
- Manual change-over between two electrical supplies.
- Main and alternative supply selection.
- Generator and mains change-over applications.
- Industrial electrical distribution systems.
- Commercial building electrical installations.
- Machinery and production equipment supply selection.
- Maintenance and alternative-feed switching arrangements.
- Three-phase systems requiring 4-pole change-over switching.
