It uses spring-loaded terminals for the main circuit, accepting 2x (0.25 to 2.5 mm²) solid or stranded conductors, with the terminal block itself rated IP20. ## Motor ratings and coordination Beyond AC-2, the contactor is rated 8.5 A in AC-4 for plugging or inching duty. For type 2 coordination, the required upstream fuse is gL/gG 20 A; type 1 coordination allows a 35 A fuse. The auxiliary contact block carries a 24 V rated value of 10 A, stepping down to 0.3 A and 6 A — these are the switching limits for the control circuit, not the main poles.","metaTitle":"Siemens 3RT1016-2AK61 SIRIUS S00 Power Contactor, 4 kW at AC","metaDescription":"Siemens 3RT1016-2AK61 SIRIUS S00 power contactor, 4 kW at AC-2 400 V, spring-loaded terminals, IP20, current production.
