This is a tool-less push-in termination — good for panel build speed, but verify the ferrule spec if using stranded on the customer's AML. The auxiliary contact block is a single instantaneous contact (NO or NC, not specified here). ## Switching capacity and coordination For motor switching, the AC-3 rating at 400 V is 5.5 kW (the standard induction-motor duty). The AC-4 rating (plugging/reversing/inching) at 400 V is 6.5 A — significantly lower, as expected for high-stress switching. Auxiliary contact ratings are given for DC switching: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. For AC auxiliary loads at 230 V, it handles 6 A; at 400 V, 3 A. For fuse coordination, Type 2 coordination requires a gL/gG 20 A fuse; Type 1 coordination allows a 35 A gL/gG fuse. Pollution degree 3 (conductive pollution, typical for industrial control panels).","metaTitle":"Siemens 3RT1015-2AM21 SIRIUS S00 Power Contactor, 24 VDC Coi","metaDescription":"Siemens 3RT1015-2AM21 SIRIUS S00 power contactor, 24 VDC coil, spring-loaded terminals, AC-3 5.5 kW at 400 V.
