Operating temperature range is -25 to +60 °C with storage from -55 to +80 °C, and the unit carries an IP20 front / IP00 terminal enclosure rating — suitable for installation within a protected enclosure where the terminals are not exposed to direct contact. ## Motor switching and operational ratings The AC-3 rating of 22 kW at 400 V governs the standard motor-starting application — this is the figure a panel builder or MRO planner should reference when matching the contactor to a motor nameplate. Maximum switching frequency varies by duty: 1 000 operations per hour at AC-1 (resistive), 800 at AC-3, 400 at AC-2 (slip-ring motor), and 300 at AC-4. Main current circuit uses screw-type terminals accepting solid conductors from 2x (0.5... 1.5 mm²) up to max. 2x (0.75... 4 mm²) for the control circuit, and stranded conductors from 2x (0.75... 25 mm²) for the power circuit. The minimum permissible conductor cross-section at 40 °C is 16 mm², which should be considered when sizing the branch circuit wiring.","metaTitle":"Siemens 3RT1036-1BP40 SIRIUS Power Contactor, S2 Size, 22 kW","metaDescription":"Siemens 3RT1036-1BP40 SIRIUS power contactor, S2 frame, 22 kW at 400 V AC-3, 41 A AC-4.
