Reversing starter in S0 frame — what ships inside
The 3RA2220-1CB23-0AP6 is a SIRIUS non-fused reversing motor starter, size S0, built as a factory-assembled combination of a 3RT2023-1AP60 contactor and a 3RA2921-1AA00 link module, with a thermal bimetallic overload relay (Class 10 trip).
DIN rail fit and panel clearances
Snap-on mounting on 35 mm standard rail, vertical position only. The envelope is 265 mm high × 90 mm wide × 120 mm deep — the depth is the dimension that reaches into the cabinet, so budget 120 mm plus wiring space behind the gland plate. Clearance requirements: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, 0 mm backwards. The zero backwards clearance means the back of the unit can sit flush against the mounting plate — no air gap needed behind the rail.

Thermal overload and wire sizing
Pollution degree 3 means it's rated for the conductive-dust environment inside a typical industrial panel.
