What this breaker does in the panel
The screw-type terminals on the main circuit accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²). That's a standard M3 terminal for the main contacts. Clearance: 9 mm at the sides, 20 mm above and below, zero forward or backward. Mounting position is any, so vertical or horizontal in a tight enclosure works.
The Class 10 trip is the key selection parameter: it allows up to 10 seconds of locked-rotor current during start, which covers most standard NEMA Design B and IEC motors up to the breaker's frame size. The -ZW95 suffix indicates a special version with a specific accessory or factory-set configuration; verify the exact overload setting range against your motor FLA before committing the BOM line.
