It is designed for motor switching and general load control in industrial control panels, with a mechanical endurance of 10,000,000 cycles typical. The contactor mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, occupying a footprint of 55 mm width, 114 mm height, and 130 mm depth. It is intended for standing installation on a horizontal mounting surface. The main contact configuration is 18...1, and an auxiliary switch is included. The coil terminals are screw-type, accepting wire sizes from 2x (0.5 to 1.5 mm²) up to 2x (0.75 to 2.5 mm²) solid or stranded. ## Duty Ratings and Switching Frequency The 3RT2035-1AB00-1AA0 supports maximum switching frequencies that vary by duty class: 1,200 operations per hour at AC-1 (resistive load), 750 at AC-2, 1,000 at AC-3 and AC-3e (motor starting), and 300 at AC-4 (plugging/inching). These figures define the thermal cycling limits for the contactor in continuous operation. Arcing time is specified at 10 to 20 ms, and switching time at AC is 10 to 18 ms. The contactor is rated for auxiliary contact current at various voltages: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.6 A at 440 V, and 2 A at 500 V. At 230 V the rating is 7.5 hp. The product is in current lifecycle stage. Compliance documentation including RoHS, REACH, and applicable IEC/UL standards is provided with the product declaration package. ## Panel Integration and Sourcing For panel integration: the 55 mm width fits standard DIN-rail spacing. Screw and snap-on mounting allows tool-less installation on 35 mm rail. Maintain the specified clearance distances (10 mm top/bottom/sides, 6 mm lateral) for adequate ventilation and arc containment.","metaTitle":"Siemens 3RT2035-1AB00-1AA0 SIRIUS Contactor, 40A 480V, S2","metaDescription":"Siemens 3RT2035-1AB00-1AA0 SIRIUS S2 power contactor. 40 A at 480 V, 24 V 50 Hz coil.
