Reversing starter kit — what ships in the carton
The 3RA2210-0EA15-2AK6: This is a Siemens SIRIUS 3RA2 reversing starter, size S00 — a pre-assembled non-fused load feeder that combines a reversing contactor pair, a thermal bimetallic overload relay, and a magnetic short-circuit trip in one DIN-rail-mountable package. The kit ships complete: the supplied contactor is a 3RT2015-1AK62, the link module is 3RA1921-1DA00, and the circuit-breaker is 3RV2011-0EA10 — no separate ordering of sub-components needed for the basic reversing function.
Trip class and motor protection — Class 10 thermal bimetal
The short-circuit trip is magnetic, meaning it responds instantaneously to fault currents above the pickup threshold, while the thermal element handles sustained overloads. This dual-protection design covers both running overload and bolted-fault events within the S00 frame.
Panel fit — dimensions and mounting
The reversing starter measures 170 mm high × 90 mm wide × 97.1 mm deep. Clearance requirements: 20 mm upwards, 10 mm downwards, 9 mm at the side, and zero forwards or backwards. These are the minimum air gaps for heat dissipation and wiring access — a panel layout that respects these keeps the internal temperature rise within the -20 to +60 °C operating range.
