It integrates a reversing contactor pair, overload protection, and short-circuit protection into a single DIN-rail or panel-mount unit — one order code instead of three separate devices. The 120 V AC control voltage variant is listed in the title spec, but the 24 V DC coil is what drives the switching logic here. The 24 V DC control coil means this starter ties directly into a PLC digital output or a 24 V DC control transformer without an interposing relay. Coil dropout below roughly 18 V DC is typical for this class, so verify your supply rail holds under load. The external protection recommendation — a 24 V DC/10 A miniature circuit breaker with type B or C tripping characteristic — keeps the control circuit coordinated with the starter's own internal protection. ## Auxiliary contacts and wiring This version carries one SPDT (NO/NC) auxiliary contact and one additional NO auxiliary contact, giving you three signal wires for status feedback or interlocking. The push-in terminals accept 0.14 to 2.5 mm² solid or ferruled stranded (AWG 26 to 14), which speeds panel wiring compared to screw terminals — strip to 8 mm and push home. No add-on terminal blocks are fitted; the 16 process terminals in the Pro slot handle the I/O connection to the upstream controller. Installation altitude goes to 5 000 m above sea level, with derating required above 2 000 m per the manual. The 707 V DC type-test isolation confirms the insulation system holds up for 690 V AC class applications.","metaTitle":"Siemens 3RA1215-0HA15-1AB0 Reversing Combination Starter","metaDescription":"Siemens SIRIUS 3RA1215-0HA15-1AB0 reversing combination starter, S00 frame, 0.55-0.8 A, 24 V DC control, 1 SPDT + 1 NO aux.
