The AC-12 operating current is 10 A, covering resistive loads. For AC-4 reversing or inching duty, the contactor is rated 6.5 A at 400 V. Pickup is at 85% of rated voltage (20.4 VDC) and dropout at 110% (26.4 VDC) — ensure your 24 V supply stays within that band under load. Main circuit terminals are screw-type, accepting 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or max 2x (0.75…4 mm²) solid/stranded. AWG equivalents: 2x (20…16), 2x (18…14), 1x 12. The front and terminal faces carry IP20 finger-safe protection, so the contactor is safe to handle in an open panel. ## Coordination and environment Type 1 coordination requires a 35 A gL/gG fuse; Type 2 requires 20 A.","metaTitle":"Siemens 3RT1015-1BB42-ZX95 SIRIUS Power Contactor, S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1015-1BB42-ZX95 power contactor, size S00, 24 VDC coil, screw terminals.
