The CB range includes enclosed ON/OFF pushbutton switches with painted iron or reinforced plastic housings, plus flush mounting versions for installation in a panel. The three-phase CBSN, CBSP, CBSY and CBSS selections cover catalog current ratings from 10A to 30A. CPB models provide two-button ON/OFF or three-button FOR/REV/STOP layouts with a separate 3A, 250VAC rating.
Select by the complete model, mounting style and rating. Surface and flush mounting variants have different dimensions and terminal sizes, even when the current and motor power entries match. The three-phase power figures below are the catalog values; their test or supply voltage is not specified in this selection document, so use a voltage-specific rating when matching a motor application.

The ON/OFF labels appear on CBSN, CBSP, CBSY, CBSS and CPB-2. CPB-3 has FOR, REV and STOP buttons. The button legends do not themselves specify the installed circuit arrangement, motor reversal wiring, interlocking or overload protection.
Dimensions are in millimeters. Front button projection and the additional small offsets in the drawings are separate from the main housing depth. Mounting fasteners are distinct from the electrical terminal screws listed above.

The flush mounting drawings distinguish the face plate from the rear switch mechanism. Use the full PDF for the required panel layout and wiring clearance; the face plate outline is not a panel cutout specification.
Order the complete CBSN, CBSP, CBSY, CBSS or CPB reference and verify the actual motor or control circuit duty, housing style, terminal connection and available mounting space. The supplied gallery shows representative plastic and metal enclosed models; the dimension document identifies each specific version.
The manufacturer specifies industrial use and requires a specially designed version plus written confirmation for high reliability energy systems, applications involving personal safety or major property risk, harsh or outdoor environments, fire or explosion risks, and military or aerospace applications.
