SIRIUS size S00 contactor with 24 VDC coil
The coil pulls in at 24 VDC nominal, rated to carry 10 A at the same voltage. That 10 A figure at 24 VDC is the DC-1 resistive rating — the number to size against if you're switching a DC load like a solenoid bank or a DC bus. For AC motor duty, the contactor's switching frequency tops out at 750 cycles per hour under AC-3 and AC-3e conditions, which covers standard motor start/stop cycles on conveyors or pumps.
The 45 mm width and 58 mm height let it fit tightly in a crowded enclosure — depth is 73 mm, so it clears a standard 80 mm deep panel.
Wiring and terminal details
For double ferruled connections, it handles 2x 0.5…1.5 mm², 2x 0.75…2.5 mm², or 2x 4 mm². That covers most panel wiring up to 12 AWG.
Switching frequency limits by duty
The contactor's mechanical life is rated at 30 million operations, but the electrical switching frequency depends on the load: 1,000 cycles/hour for AC-1 resistive loads, 750 for AC-2 and AC-3 motor duty, and 250 for AC-4 plugging/reversing. The arcing time sits at 10 to 15 ms, with a dropout delay of 38 to 65 ms at DC. That dropout window matters when coordinating with a safety circuit — the contacts break reliably within that span after coil power drops.
