It is the switching workhorse inside a motor starter or control circuit — not the main power contactor, but the relay that signals, interlock, or sequences the logic side of the panel. The AC coil is rated for 230 V at both 50 Hz and 60 Hz, with an operating range of 0.8...1.1 times nominal at 50 Hz and 0.85...1.1 at 60 Hz. The contact ratings tell you what it can switch across different control voltages: 6 A at 24 V, 3 A at 110 V, 1.2 A at 220 V, 10 A at 230 V, 3 A at 400 V, and 1 A at 690 V. The AC-12 maximum operational current is 6 A, and the DC-12 and DC-13 maximum operating frequency is 1 000 switching cycles per hour. For high-speed applications, the general AC and DC switching frequency is rated at 10 000 1/h, but the DC-12/DC-13 derating to 1 000 1/h is the figure that governs real inductive DC loads like DC contactor coils. Wire termination accepts 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or 2x 4 mm² solid or stranded; for finely stranded conductors with core-end processing, use 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²). AWG equivalents are 2x (20...16), 2x (18...14), and 2x 12. ## Coil power and switching The AC coil draws 37 VA apparent pick-up power and 5.7 VA apparent holding power, with an inductive power factor of 0.8 for closing power. That pick-up surge matters for transformer sizing in the control circuit — a panel with multiple contactor relays can see a cumulative inrush that dims the control voltage momentarily. The 5.7 VA holding power is modest, keeping thermal rise low in a crowded enclosure.","metaTitle":"Siemens 3RH6140-1AP00 SIRIUS Contactor Relay, 4 NO, AC Coil","metaDescription":"Siemens 3RH6140-1AP00 SIRIUS contactor relay, size S00, 4 NO contacts, AC coil 230 V 50/60 Hz.
