What ships in the carton — a complete starter kit
The 3RA2110-1HA15-1BB4 is a Siemens SIRIUS direct-on-line (DOL) motor starter, size S00, that arrives as a factory-assembled unit with the contactor and overload relay already linked. No separate ordering of the contactor and link module — the kit includes the 3RT2015-1BB41 contactor and the 3RA1921-1DA00 link module, so the tech gets one assembly to install, not a bag of loose parts.
Panel fit and mounting — screw or snap-on DIN rail
Mounts vertically on 35 mm DIN rail via the integrated snap-on foot, or can be screw-mounted to a backplate. The S00 frame footprint is 45 mm wide, 97 mm deep, and 167 mm tall — fits standard 45 mm-wide feeder positions in a motor control centre. Clearance requirements: 50 mm above, 20 mm below, 20 mm to the side, and 20 mm forward for wiring access. No clearance needed behind the unit. Ambient operating range is -20 to +60 °C.
Wiring and coil — 24 V DC, screw terminals
The main circuit uses screw-type terminals — standard for panel wiring with ring or fork lugs. The coil is rated 24 V DC, so confirm your control voltage matches before landing the wires. The starter is a Type of Assignment 1 device, meaning it is a non-reversing DOL starter. No PROFIsafe or PROFINET IO protocol onboard — this is a conventional electromechanical starter, not a networked soft starter or VFD.
