For resistive loads (AC-1), the maximum operating rate is 1 200 cycles per hour; for AC-4 plugging duty, that drops to 250 cycles per hour — the thermal capacity of the S2 frame governs the duty cycle, not just the steady-state current. Coil draw at 24 V rated value is 10 A, at 60 V it is 2 A, and at 230 V it is 6 A — these are the pick-up and hold currents the PLC output or control transformer must supply. Front protection is IP20 (finger-safe), while the terminal area is IP00 — the panel builder must ensure the gland plate and enclosure maintain the overall IP rating. No separate REACH or UL declaration is in this evidence, but as a Siemens SIRIUS catalog part it carries CE marking under the Low Voltage Directive by design. Main current circuit terminals are screw-type, accepting solid conductors from 2x (0.5 to 1.5 mm²) up to 2x (0.75 to 4 mm²), and stranded from 2x (0.75 to 25 mm²). The minimum permissible cross-section at 40 °C is 16 mm² for the main circuit — this is the thermal derating floor, not a recommendation for smaller control wiring. Auxiliary and coil terminals use the same screw clamp range. Height is 112 mm. When planning panel layout, allow clearance above and below for arc venting and screwdriver access to the terminals.","metaTitle":"Siemens 3RT1034-1AB04 SIRIUS Power Contactor, 15 kW AC-2 at","metaDescription":"Siemens SIRIUS 3RT1034-1AB04 power contactor, S2 frame, 15 kW AC-2 at 400 V, 55 mm wide, screw terminals, current production.
