Reversing starter for 60 mm busbar panels
The 3RA2210-4AD18-2AK6: This is a SIRIUS non-fused reversing load feeder, size S00 — a factory-assembled combination of a reversing contactor and a circuit-breaker in one package, designed for snapping onto 60 mm busbar systems. The Class 10 trip characteristic means it will hold starting inrush long enough for standard squirrel-cage motors but trip before the winding overheats on a stalled rotor.
What's in the box and how it mounts
The unit ships with a 3RT2018-1AK62 contactor and a 3RA1921-1DA00 link module pre-assembled — no separate contactor or overload relay to wire. Mounting is vertical only, snapping onto a 60 mm busbar system; the depth is 155.1 mm, width 90 mm, height 200 mm, with 20 mm clearance needed above and 10 mm below.
