Closing and holding power is 3.3 W DC — steady-state draw is low enough that a standard 24 VDC power supply can drive multiple contactors without derating. Main contacts are spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG). The IP20 finger-safe terminal shroud means the panel builder doesn't need additional touch protection at the contactor — it's safe for live work with a screwdriver, not fingers. For DC switching, the contactor is rated 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. These are resistive-load figures; inductive DC loads (relays, solenoids) need a flyback diode across the load or the contacts will arc on opening. The 10 A at 24 VDC covers most solenoid valve banks and small DC motor brakes. On AC motor duty, the contactor delivers 6 A at 230 V (approx. 1.5 kW), 3 A at 400 V (4 kW in AC-2, 8.5 A in AC-4), and 5.5 kW at 690 V. The AC-4 rating of 8.5 A at 400 V is the one to watch for reversing or plugging duty — it's lower than the AC-3 thermal current because of the higher switching frequency and arcing stress. For type 1 (contactor may need replacement after fault), a 35 A fuse is acceptable. The SCCR depends on the upstream breaker — the contactor itself doesn't limit fault current. The 45 mm width and 114 mm depth fit standard DIN-rail spacing with 6 mm side clearance to adjacent devices. ## Where it fits — panel integration Side-by-side mounting is allowed (no derating required for adjacent contactors at rated current up to 60 °C ambient). The spring-loaded terminals accept 0.25 to 2.5 mm² (24 to 14 AWG). Strip length is typically 8-10 mm for spring-cage terminations. No special tools needed beyond a screwdriver to push the orange release button. This contactor carries CE marking for the European market and is designed to meet IEC 60947-4-1 for contactors and motor-starters. RoHS and REACH compliance documentation is available from Siemens upon request.","metaTitle":"Siemens 3RT1016-2BW44 SIRIUS Power Contactor, Size S00, 24 V","metaDescription":"Siemens 3RT1016-2BW44 SIRIUS power contactor, Size S00, 24 VDC coil, 10 A at 24 VDC.
