ABB's 1SDA104686R1 fixed part equips a Tmax XT5 moulded case circuit breaker for withdrawable installation, rated 400 A over four poles with extended front (EF) terminals. It bolts to the switchboard busbars and provides the disconnecting contacts the four-pole breaker body plugs into when racked to the connected position.

Selection Notes
Specify the four-pole fixed part rather than its three-pole counterpart (1SDA104682R1) when the neutral conductor needs to be switched through the withdrawable breaker instead of run on a fixed bar. The withdrawable (W) design suits switchboards where racking the breaker to isolated or test position is a required maintenance step, unlike the lighter plug-in (P) fixed part used on simpler boards.
