Resistive loads up to 10 A AC-12 are within range, so it handles heater banks or ballast loads without derating. The DC coil draws 3.3 W during closing and holding, a constant-power design that simplifies power supply sizing — no AC hum, no separate holding-economy circuit needed. Screw terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) per clamp, with AWG equivalents 2x (20 to 16), 2x (18 to 14), and 1x 12. This range covers most panel wiring from signal-level to motor-circuit branch feeds. Type 1 (contactor may need replacement after fault) allows a 35 A fuse. One instantaneous auxiliary contact is built in (1 NO or 1 NC depending on variant wiring), providing feedback for PLC interlocks or status indication. Mechanical life is typical 30 million operations — a figure that assumes dry switching; actual life under load depends on the duty class and switching frequency.","metaTitle":"Siemens 3RT1016-1BF41 SIRIUS Power Contactor, S00, 110 VDC C","metaDescription":"Siemens SIRIUS 3RT1016-1BF41 power contactor, size S00, 110 VDC coil, 4 kW AC-2 at 400 V.
