The magnetic short-circuit trip handles fault clearing independently of the thermal element, so a phase-to-phase fault on the load side opens the circuit breaker instantly without waiting for the bimetal to heat. ## Panel fit and mounting constraints This starter mounts on 35 mm standard DIN rail via screw and snap-on fastening, or can be screw-mounted to a backplate. Clearance requirements: 50 mm above, 20 mm below, 20 mm to the sides, and 20 mm forward for wiring access. No clearance needed behind the unit. Mounting position is vertical only — horizontal mounting changes the thermal trip characteristic. Main circuit and auxiliary/control circuit connections use spring-loaded terminals — no screw torque to verify, but the wire must be solid or ferruled stranded to engage the cage properly. ## What's in the box — supplied sub-assemblies The starter ships with three factory-matched components: a 3RT2015-2FB41 contactor, a 3RV2011-1AA25 circuit breaker, and a 3RA2911-2AA00 link module that interconnects them. The contactor coil is 24 VDC — confirm your control voltage matches before wiring. The auxiliary switch extension is available as a field-addable option (product extension auxiliary switch = Yes), so you can add feedback contacts for PLC status monitoring without replacing the starter. ## Environmental and compliance envelope Operating temperature range is -20 to +60 °C, with 10-95 % relative humidity non-condensing. Storage and transport range is -50 to +80 °C.","metaTitle":"Siemens 3RA2115-1AE15-1FB4 SIRIUS Direct Starter","metaDescription":"Siemens 3RA2115-1AE15-1FB4 SIRIUS direct online starter, 550 W at 400 V AC-3, Class 10 thermal overload, 24 VDC coil.
