The 3RT1016-2WB41 is a SIRIUS power contactor in size S00, the smallest frame in the series, designed for switching motor loads up to 5.5 kW at 690 V. Pickup voltage is 0.85 x rated (20.4 V), dropout at 0.15 x rated (3.6 V); per the datasheet, the coil holds reliably down to 18 V but drops out below that threshold. The spring-loaded main terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG), which covers the typical motor-circuit wiring for this frame size. Rated operational current varies by duty: at AC-1 (resistive) it carries 10 A at 230 V, 3 A at 400 V. For motor switching, the AC-2 rating at 400 V is 4 kW, and AC-4 (plugging/inching) at 400 V is 8.5 A. The DC switching ratings are 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — these are the maximums for resistive DC loads; inductive DC loads will need derating.
For type of coordination 2 (contactor remains operational after clearing the fault), the fuse is gL/gG 20 A. The contactor is equipped with a built-in varistor surge suppressor across the coil, so no external suppression module is needed for the DC coil circuit. This simplifies panel wiring and reduces component count.
