Dimensions are 152 mm depth, 70 mm width, and 140 mm height — the width is the critical dimension for rail fill calculations when ganging contactors. ## Auxiliary contact ratings and wiring The contactor carries 1 normally open instantaneous auxiliary contact. Main power terminals accept stranded wire from 6 to 70 mm². At 600 V AC the rating drops to 0.1 A — this matters for control circuits running at higher voltages where the contact can only switch minimal current. The coil is AC type with a rated voltage of 230 V at 50 Hz. Arcing time spans 10 to 21 ms at AC, with a typical mechanical endurance of 10,000,000 operating cycles. ## Lifecycle and sourcing for project milestones Up to 2 attachable auxiliary switch blocks can be added to the contactor, extending its control circuit capacity without changing the base unit.","metaTitle":"Siemens 3RT2448-1AP00 SIRIUS Contactor, Size S3, AC Coil","metaDescription":"Siemens 3RT2448-1AP00 SIRIUS contactor, Size S3, screw and snap-on DIN rail mount, 1 NO auxiliary contact.
