At 690 V the same duty class drops to 11.4 kW — the voltage step reduces the available motor power, so verify your line voltage against the 500 V or 690 V column. For heavy jogging or inching (AC-4), the contactor is rated 41 A at 400 V; that is the current limit for plugging or reversing service where the motor is re-energized against a rotating field. The front panel carries an IP20 rating — touch-safe against finger contact, but the terminal area itself is IP00, so the wiring compartment must be inside an enclosure or panel. Solid conductors accept 2x (0.25 to 2.5 mm²); stranded accept 2x (0.75 to 25 mm²). Substance prohibitance compliance is dated 05/01/2012. The part carries no explicit UL or CSA listing in the evidence. ## Environmental limits and pollution rating Electrical life varies by duty: AC-1 (resistive) allows 1 000 000 operations per hour maximum, AC-3 (motor start/run) 800 000 per hour, AC-4 (plugging/reversing) 300 000 per hour. These numbers matter for coordination with upstream short-circuit protection — the arc duration is short enough to avoid nuisance fuse blowing on most motor circuits. The S2 frame measures 55 mm wide, 112 mm high, 164 mm deep. That depth includes the terminal projection — verify clearance behind the DIN rail, especially if the panel has a shallow gland plate. The width is a single 55 mm module, so it occupies one standard 18 mm pitch unit on the rail.","metaTitle":"Siemens 3RT1036-3AP08-1MA2 SIRIUS Power Contactor, 30 kW at","metaDescription":"Siemens 3RT1036-3AP08-1MA2 SIRIUS power contactor, size S2, 30 kW at 500 V AC-3.
