It ships as a coordinated set: the supplied 3RT2015-2AP01 contactor, the supplied 3RV2011-0EA20 circuit breaker with thermal (bimetallic) overload and magnetic short-circuit trip, and the 3RA2911-2AA00 link module that ties them together electrically and mechanically. The busbar adapter 8US1251-5DT11 is also included, so this is a bolt-on motor branch ready for panel integration — no separate ordering of the contactor, breaker, or adapter. Rated insulation voltage is 690 V, and the maximum AC-3 operating voltage is also 690 V — this covers 400 V and 480 V motor circuits common in North American and European panels. The operating frequency is 50/60 Hz, so it works on either line frequency without derating. The thermal overload is bimetallic, not electronic — it tracks motor heating via a physical bimetal strip. That is simpler and more rugged in dirty or high-vibration environments, but it has a narrower ambient compensation range than an electronic relay. The ambient compensation is rated for -20 to +60 °C operating, which covers most indoor panel conditions. Dimensions are 45 mm wide, 260 mm high, and 155 mm deep. The 45 mm width is the key panel-space number — it occupies a single 45 mm slot on the busbar system. Mounting is vertical only, and the clearance requirements are: 50 mm upward, 20 mm forward, 20 mm at the side, 10 mm downward, and 0 mm backward (it sits flush against the busbar). These clearances matter for heat dissipation and for the magnetic trip to operate correctly. Because it is a factory-coordinated set, the coordination between the contactor and breaker is pre-validated by Siemens. That saves the panel builder the engineering time of selecting and testing a separate contactor and breaker combination. The type of coordination (Type 1 or Type 2) is determined by the specific breaker-contactor pairing; this assembly uses the 3RV2011-0EA20 breaker, which is a standard S00 frame breaker. The main current circuit uses spring-loaded terminals — no screwdriver needed for the power wiring. That speeds up panel wiring and reduces the risk of loose connections over time. Snaps onto 60 mm busbar systems (the standard Siemens busbar grid). The busbar adapter 8US1251-5DT11 is included, so no separate adapter purchase. The mounting position is vertical only — do not install horizontally or inverted, as the thermal overload calibration assumes vertical orientation for proper heat convection.","metaTitle":"Siemens 3RA2110-0EH15-1AP0 SIRIUS Direct Starter, S00, 45mm","metaDescription":"Siemens 3RA2110-0EH15-1AP0 SIRIUS direct-on-line starter, size S00, 45mm wide, for 60mm busbar systems.
