Integrator note — 3RT6016-1BM42
The Siemens 3RT6016-1BM42 is a SIRIUS power contactor in size S00, designed for switching motor loads in control panels. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 50022, occupying a 45 mm width — a standard slot for this frame class. Rated for AC-3 and AC-3e duty up to 690 V, with motor output ratings of 7.5 kW at 230 V, 13 kW at 400 V, and 22 kW at 690 V (all at 60 °C ambient). That 60 °C derating curve matters: if your panel ambient runs cooler, you get headroom; if it pushes above 60 °C, you need to downrate further per the thermal curve. Coil draws 6 A at 24 V rated value, 1 A at 110 V, and 0.3 A at 220 V — verify your control transformer sizing against the inrush, especially on long cable runs where voltage drop at pickup can cause chatter.
Lifecycle & compliance
Substance prohibitance compliance date is 05/01/2012, aligning with RoHS and REACH requirements for the European market. Pollution degree 3 rating means it's suitable for industrial environments with conductive pollution, typical of control panels not in clean-room conditions.
Integration & mounting
Mounting position allows +/-180° rotation on a vertical surface and can be tilted forward/backward by +/-22.5° — useful when fitting into tight enclosures or angled subpanels. Side-by-side mounting is permitted, so you can gang multiple contactors without derating for heat buildup, provided the ambient stays within the -25 to +60 °C operating range. Main circuit terminals accept screw-type connections for 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid/stranded, plus AWG equivalents 2x (20-16), 2x (18-14), 2x 12. Minimum conductor sizes at 40 °C is 4 mm²; at 60 °C it's 2.5 mm² — the higher ambient requires thicker wire to keep terminal temperatures within limits. Dimensions are 73 mm deep, 45 mm wide, 57.5 mm tall — the S00 footprint. The auxiliary switch extension is available (product extension auxiliary switch: yes), so you can add a side-mount block for status feedback without increasing the width beyond the standard 45 mm slot.
Switching frequency & mechanical life
Mechanical life is rated at 30,000,000 operating cycles typical. Switching frequency limits: 1,000 1/h at AC-1 (resistive loads), 750 1/h at AC-3 and AC-3e (motor starting), 250 1/h at AC-4 (plugging/inching), and 10,000 1/h at DC. For high-cycle applications like conveyor indexing or valve actuation, the AC-3 limit of 750 operations per hour is the practical ceiling — exceeding it accelerates contact wear.
