The Siemens 3VM9317-0SS10 is a mounting screw kit — four M5 x 95 mm metric screws with matching nuts — designed for the 3VM13 and 3VM14 circuit breaker family. It fits both 3-pole and 4-pole versions of those breakers, plus their plug-in unit variants. If you're retrofitting or installing a 3VM breaker into a panel, this is the hardware kit that secures it to the mounting surface.
The kit contains four M5 x 95 mm screws and four nuts. That's enough to mount one 3-pole or 4-pole breaker. The 95 mm length gives you room to pass through the breaker base and into a mounting plate or rail adapter. Keep the torque within the breaker's specified range — overtightening M5 hardware in a molded case can crack the base. The packaging dimensions are 150 x 100 x 5 mm, which is essentially a flat envelope — easy to store in a bin or drawer.
