The 3RT2016-1BB44: The Size S00 frame (45 mm wide, 58 mm high, 117 mm deep) fits standard 35 mm DIN rail per DIN EN 60715, with screw and snap-on mounting. The 24 VDC coil pulls in at 0.8 of rated voltage and holds across the full operating range of -25 to +60 °C. Switching frequency varies by duty: up to 1000 cycles/hour at AC-1 (resistive), 750 cycles/hour at AC-3 (motor start/run), and 250 cycles/hour at AC-4 (plugging/inching). The auxiliary contact ratings cover 24 VDC (6 A) down to 220 V (0.3 A) — enough for PLC or relay interface signals. No built-in auxiliary switch block is included, so if you need auxiliary contacts, order a separate block. Wire range accepts solid or stranded from 0.5 to 4 mm², with dual-wire capacity up to 2x 4 mm². Clearance distances: 10 mm upward/forward/downward, 6 mm to the side. The contactor can be mounted on a vertical surface with ±180° rotation and ±22.5° tilt — useful for tight panel layouts.
