Application and source arrangement
The original reference labels source A as city power and source B as generator. This is the 110–120 V L+N unit; do not substitute the separate 230 V or PV/inverter versions. The source does not establish generator starting/stopping control.
Automatic switching
The manufacturer gives both switching and action time as less than 50 ms. This is a finite transfer-time reference, not a zero-break UPS specification.
Terminal protection
The original illustration shows the terminal shields and contact barriers intended to reduce accidental contact.
Manual and automatic modes
Select manual mode before operating the source handle. The original front-panel diagram identifies the manual handle and mode selector.
Mounting
The switch is designed for 35 mm DIN-rail mounting with access to the power and control terminals.
Original two-pole parameter reference
The manufacturer’s parameter image below shows the common 125 A two-pole sample at 110 V. The offered 63 A current is explicitly in the written family scope; no photo rating has been changed.
Dimensions
The original two-pole drawing retains the 108 × 109 mm outline references. The separate side drawing gives a 78 mm reference.
Side and load-terminal view
The original side view identifies the load-side arrangement and depth reference.
