For reference, the AC-3 rating at 500 V is 30 kW, and at 690 V it is 11.4 kW. Main current circuit connections use screw-type terminals. The terminal block accepts stranded wire from 2x (0.75... 25 mm²) and solid wire from 2x (0.25... 2.5 mm²). The combined solid-or-stranded range is 2x (0.75... 16 mm²). At 40 °C, the minimum permissible conductor cross-section is 16 mm². The front of the contactor carries an IP20 rating, meaning finger-safe access during panel servicing. The terminal area itself is IP00, so live parts are exposed when the panel door is open — standard for this class. Switching frequencies: 1 000 cycles/hour at AC-1 maximum, 800 at AC-3, 400 at AC-2, and 300 at AC-4. Dimensions: 112 mm height, 55 mm width, 130 mm depth. Side-by-side mounting is permitted, which simplifies multi-contactor panel layouts. The contactor carries a substance prohibitance date of 05/01/2012, indicating RoHS compliance from that date. Standard Siemens SIRIUS documentation (declaration of conformity, CE marking) applies per the brand's product line.","metaTitle":"Siemens 3RT1036-3BE40 SIRIUS Power Contactor, S2, 22 kW AC-2","metaDescription":"Siemens 3RT1036-3BE40 SIRIUS S2 power contactor.
