Screw fixing mounts it directly to the panel backplate or a mounting rail, with dimensions 202 mm depth, 145 mm width, 210 mm height — factors that dictate cabinet layout and gland-plate clearance. This contactor includes an auxiliary switch and is rated for DC coil control, which means it drops out predictably on DC circuits without the AC hum or dropout delay. The 72 VDC coil is the critical spec for fit — verify your control voltage matches, as DC coils are polarity-sensitive and have a different pull-in characteristic than AC. The contactor's mechanical life is typical at 10,000,000 operations, but the electrical endurance depends on the load category: at AC-3 (motor starting) it can cycle 500 times per hour, at AC-4 (inching/jogging) only 130 times per hour. For DC loads, DC-1 rates 350 operations per hour, while DC-3 and DC-5 both rate 250. These cycle rates directly affect whether this contactor can handle your application's duty cycle without overheating. Auxiliary contact ratings are given at specific DC voltages: 6 A at 24 VDC, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V. Use these values when sizing control relays or PLC inputs downstream — the 24 V rating is generous, but at 125 V the current drops to 0.9 A, so don't assume the full 6 A holds at higher voltages. ## Mounting and Clearance Requirements These clearances are for arc flash and cooling — in a tight cabinet, forward clearance of 20 mm is the tightest dimension to plan for. Screw fixing uses one hole, 11 mm diameter. This is standard for control wiring up to 14 AWG; for larger power cables, check the contactor's main terminal specs separately.","metaTitle":"Siemens 3RT1064-2XJ46-0LA2 SIRIUS Power Contactor, S10, 72 V","metaDescription":"Siemens SIRIUS 3RT1064-2XJ46-0LA2 power contactor, S10 size, 72 VDC coil, 202 mm depth.
