For AC-4 duty (plugging, inching) at 400 V, the rating drops to 8.5 A — significantly less than the AC-3 rating would be, because AC-4 involves higher switching stress. The coil draws 11 W on closing and holds at 4 W DC, which matters for power supply sizing in a multi-contactor panel. With type of coordination 2, the required fuse is gL/gG 20 A; for type 1 coordination, it's 35 A. The varistor across the coil handles the inductive kick — no external snubber needed, which saves a terminal and a wiring step. Mechanical life of 30,000,000 operations typical.","metaTitle":"Siemens 3RT1017-2KJ82-0LA0 SIRIUS S00 Power Contactor, 72 V","metaDescription":"Siemens SIRIUS S00 power contactor 3RT1017-2KJ82-0LA0 with 72 V DC coil, spring-loaded terminals, AC-2 5.5 kW at 400 V.

The 3RT1017-2KJ82-0LA0 has a 72 V DC coil with spring-loaded terminals; verify the peer's coil voltage and wiring before assuming a drop-in swap."},{"question":"Will 3RT1017-2KJ82-0LA0 drop into a panel specified for 3RT1016-1BB42?","answer":"Both share the S00 frame and the same 45 mm width and DIN rail mounting, so the physical footprint is identical. The difference is the coil voltage and terminal type — the 3RT1017-2KJ82-0LA0 uses a 72 V DC coil and spring-loaded terminals, so the panel wiring and control voltage must match."},{"question":"Where can I buy 3RT1017-2KJ82-0LA0 and how is it quoted?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
