SIRIUS 3RT2015-2AK61-ZX95 — Compact Power Switching with Spring-Terminal Convenience
Its spring-type terminals on both the coil and main contacts eliminate screw-torque checks — strip, insert, done. Rated for continuous operation from -25 to +60 °C ambient, it handles the thermal load inside a crowded enclosure without derating surprises. The built-in auxiliary switch (1 N/O + 1 N/C typical for this frame) saves a separate add-on block for basic feedback or interlock signals.
Switching Duty and Mechanical Life
Maximum switching frequency depends on the load type: 1000 operations/hour for AC-1 resistive loads, 750/h for AC-2 and AC-3 motor starting, and 250/h for AC-4 plugging/inching. Arcing time runs 10 to 15 ms; pick-up and drop-out delays are 7 to 13 ms, which matters for sequencing logic that expects a predictable contact closure window. Auxiliary contact ratings span the control-voltage range: 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. The 0.14 A at 440 V rating is a reminder that inductive loads at higher voltages need derating — check the coil inrush of your PLC output card against that curve.
Wiring and Clearance
Spring-clamp terminals accept solid or stranded wire from 0.5 to 4 mm² (2x 0.5–4 mm² per clamp for looping).
