The coil is rated 20-33 V, with a 6.5 A inrush peak and 3.5 VA holding at both 50 and 60 Hz. Switching capacity at 24 V is 10 A, dropping to 2 A at 48 V and 60 V, and 1 A at 110 V — these figures govern auxiliary or control-circuit use, not the main power path. Switching frequency varies by duty: 900 cycles/hour at AC-1 (resistive), 850 at AC-3 and AC-3e (motor starting), 350 at AC-2 (slip-ring motors), and 250 at AC-4 (plugging/inching). Arcing time runs 10-20 ms with pick-up and drop-out delays of 38-57 ms on both AC and DC. The S3 frame measures 70 mm wide × 140 mm high × 152 mm deep. Main power terminals accept solid conductors 2.5-16 mm² or stranded 6-70 mm². Auxiliary/control terminals accept 2× (0.5-1.5 mm²) or 2× (0.75-2.5 mm²) solid or stranded. The screw-type coil terminal is clearly marked; verify torque values per the mounting instructions before energizing.","metaTitle":"Siemens 3RT2046-1NB30-0CC0 SIRIUS S3 Power Contactor, 152 mm","metaDescription":"Siemens SIRIUS 3RT2046-1NB30-0CC0 S3 power contactor, 152 mm depth, screw-type coil terminals, 20-33 V coil.
