The coil connection uses spring-type terminals; main power wiring accepts stranded cable from 25 to 120 mm². Mechanical life is typical 10,000,000 operations. Switching frequency depends on duty: AC-1 (resistive) max 800 ops/h, AC-2 400 ops/h, AC-3 (motor start) 1000 ops/h, AC-4 (plugging/inching) 130 ops/h. ## Auxiliary Contact Ratings and Wiring The auxiliary switch is rated for switching at various control voltages: 10 A at 24 V rated value, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V. These are the contact ratings under the respective DC or AC conditions — useful for sizing the control circuit, not the main power path. Wire the auxiliary via the spring-type terminals; the solid or stranded range for these is 2x (0.25 to 2.5 mm²). ## Integration and Clearance Physical envelope: 172 mm height, 120 mm width, 170 mm depth. Mounting uses four 9 mm diameter holes on a screw-fixing pattern. These clearances matter for heat dissipation and arc-flash containment — don't crowd the enclosure. The lifecycle stage for 3RT1054-2AT36 is listed as current.
