At 500 V the contactor is rated for 30 kW, and at 690 V for 11.4 kW, so it handles higher-voltage motor circuits but with reduced power due to the voltage derating. The mechanical endurance is 10 million cycles typical, with maximum switching rates of 1000 cycles/hour at AC-1, 800 at AC-3, and 300 at AC-4 — so for high-duty reversing applications, the AC-4 rate governs the lifetime. The front is IP20 protected (finger-safe), while the terminals are IP00 — so the panel enclosure provides the terminal protection. The main circuit screw terminals accept 2x (0.75 to 25 mm²) stranded wire or 2x (0.25 to 2.5 mm²) solid wire, with a minimum permissible cross-section of 16 mm² at 40 °C. Side-by-side mounting is allowed without derating, which saves panel width when grouping multiple contactors. The S2 frame measures 55 mm wide, 112 mm high, and 130 mm deep — check your enclosure depth before committing.","metaTitle":"Siemens SIRIUS 3RT1036-3BB40 Power Contactor, 24 VDC Coil, S","metaDescription":"Siemens SIRIUS 3RT1036-3BB40 power contactor, S2 size, 24 VDC coil, rated 22 kW at AC-2 400 V and 41 A at AC-4 400 V.
