The 3RA2115-1BA16-2BB4-ZX95: Width is 45 mm, depth 97 mm, height 167 mm — the S00 form factor fits standard 45 mm slot pitch on a 35 mm DIN rail with screw and snap-on mounting. Clearance requirements: 50 mm upward, 20 mm forward, 10 mm downward, 20 mm at the side; zero backward clearance needed. Mounting position is vertical only; the thermal bimetallic overload release is temperature-compensated over -20 to +60 °C operating range.
Supplied components and wiring
The starter ships as a pre-assembled unit containing contactor 3RT2016-1BB42 and link module 3RA1921-1DA00 — no separate ordering of contactor and overload. Main circuit terminals are screw-type; the circuit-breaker size is also S00, matching the feeder size.
