What this DOL starter delivers on a motor branch
The 3RA2115-0EA16-2BB4-ZX95 is a SIRIUS direct-on-line starter — a pre-assembled combination of contactor, overload relay, and circuit breaker in one Size S00 footprint.
Panel fit and mounting constraints
The mounting position is vertical, and the enclosure must allow 50 mm clearance above and 20 mm forward for ventilation and arc containment — no clearance needed at the back. The link module 3RA1921-1DA00 connects the contactor and breaker internally, reducing wiring time on the panel build.
Coil voltage and control compatibility
The control coil is rated 24 V DC — a standard PLC output voltage for industrial control panels. No PROFIsafe or PROFINET IO protocol is integrated; this is a conventional electromechanical starter with a magnetic short-circuit trip and thermal overload. Operating frequency is 50/60 Hz, so the same unit works on 50 Hz or 60 Hz line supplies without derating the motor power rating.
