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. ## Environmental range","metaTitle":"Siemens 3RT2016-1FB42 SIRIUS Power Contactor, 24 VDC Coil, S","metaDescription":"Siemens 3RT2016-1FB42 SIRIUS power contactor, 24 VDC coil, size S00 frame.
