What it is
The ABB 1SAM250005R1011 is a manual motor starter — an accessory-line item sitting under Contactor & Starter Accessories & Parts in the ABB motor-protection catalogue — that pairs with the matching contactor/breaker frame to give a local motor disconnect and overload function on a panel door orDIN sub-assembly. Class placement: Circuit Breakers, Fuses & Protection > Contactors and Starters > Contactor & Starter Accessories & Parts, which is the accessory tier rather than the breaker body itself.
