SIRIUS 3RT1016-1TP01 — Size S00 Power Contactor, 24 VDC Coil
The Siemens 3RT1016-1TP01 is a SIRIUS power contactor in the compact size S00 frame, intended for switching motor loads in control panels and industrial machinery. It is rated for AC-4 duty at 8.5 A at 400 V, which covers the demanding inrush and plugging/reversing cycles of squirrel-cage motors. The coil is 24 VDC, with an integrated varistor surge suppressor across the coil terminals — no external snubber needed for DC switching transients. Mounting is via screw or snap-on onto 35 mm DIN rail per EN 50022, with side-by-side mounting permitted — no derating gap required between units. The 45 mm width fits standard panel layouts. Pollution degree 3 rating means it is suited for industrial environments with conductive pollution (condensation, light dust). The main circuit uses screw-type terminals accepting 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid/stranded conductors — typical for control panel wiring. The auxiliary contact block is rated for DC switching: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V — these are the make/break limits for DC loads, which are more restrictive than AC due to arc extinction.
Integration Notes
Operating temperature range is -25 to +60 °C during operation, with a maximum operating altitude of 2,000 m without derating. The contactor is rated for 50/60 Hz operation with a voltage tolerance of 0.8 to 1.1 times rated at 50 Hz and 0.85 to 1.1 at 60 Hz — the coil will hold in across typical line variations. For short-circuit protection, the manufacturer specifies a gL/gG fuse rated at 20 A for type 2 coordination (no welding of contacts under fault). The front face carries an IP20 finger-safe protection rating; the terminals themselves are also IP20 when wired. Mechanical endurance is rated at 30 million operating cycles typical — this is the no-load mechanical life. Electrical life will be lower and depends on the switched current and duty cycle.
