S00 direct starter on 60 mm busbars
The Siemens 3RA2110-0JH15-1AP0 is a SIRIUS direct-on-line starter in size S00, designed specifically for snapping onto 60 mm busbar systems — a space-saving alternative to DIN-rail mounting when the busbar is the primary distribution backbone. It ships as a pre-assembled unit containing the 3RT2015-2AP01 contactor and the 3RA2911-2AA00 link module, so the BOM line covers the starter function without separate component procurement.
Dimensions and clearance for panel layout
Clearance requirements are specified for vertical mounting: 50 mm upwards, 20 mm forwards, 20 mm at the side, 10 mm downwards, and 0 mm backwards — the zero backward clearance confirms the unit sits flush against the busbar backplane, so no additional rear gap is needed.
Termination, environment, and protocol support
Main current circuit connections use spring-loaded terminals — no screw torque verification needed, which speeds panel wiring and eliminates the risk of loose connections under thermal cycling. Operating temperature range is -20 to +60 °C with temperature compensation active across the same band; storage and transport limits extend from -50 to +80 °C. This covers most indoor industrial environments without derating, though the 60 °C ceiling should be checked against enclosure internal ambient if mounted near heat sources. The starter does not support PROFIsafe or PROFINET IO protocols — it is a conventional hardwired direct starter, not a motor starter with integrated fieldbus communication. For networked applications, a separate communication module or a SIRIUS 3RA6/3RA7 series starter with PROFINET would be required.
Lifecycle and sourcing posture
For audit purposes, the supplied contactor and link module part numbers (3RT2015-2AP01, 3RA2911-2AA00) are documented for traceability against the original equipment specification.
