It lands as a current-production part (lifecycle stage: current), so it's still a standard BOM line, not a scavenger hunt. The 24 VDC coil pulls in at nominal voltage and drops out reliably below the minimum hold threshold — standard for PLC-driven panels where the DC supply is shared across I/O and contactors. Main contact ratings: 10 A at 24 V rated value, 3 hp at 230 V, and 3 A at 400 V — so it'll handle small motors, fans, pumps, and resistive heaters inside a 480 V panel. The auxiliary switch (1 N/O + 1 N/C, 18...8 configuration) gives you feedback for the PLC or a seal-in circuit without bolting on a separate aux block.
The S0 frame is 45 mm wide, 102 mm tall, 97 mm deep — fits the standard panel layout without surprises. That's tight enough for a dense row of contactors on the rail, but leave the side gap for heat rise if you're running near the AC-3 switching limit of 1,000 cycles per hour.
Duty and Environment
Rated for 1,000 operating cycles per hour under AC-1, AC-2, AC-3, and AC-3e duty; drops to 300 cycles per hour under AC-4 (plugging/reversing). Storage temperature spans -55 to +80 °C, which matters if the spare sits in a non-climate-controlled warehouse for a couple years. The arcing time is 10 ms, and the switching times at AC are 4 to 16 ms — fast enough for most sequencing but not a high-speed transfer switch.
