The 3RT1516-1AM20: The 24 VDC coil draws 4.4 VA at 50 Hz and 0.27 A at 60 Hz, with operate times of 4–30 ms on AC and 25–100 ms on DC. Arcing time runs 10–15 ms. Mechanical life is 30 000 000 operations typical. Auxiliary contacts (1 NO + 1 NC) each carry 9 A. The main circuit withstands 6 kV rated impulse voltage. Wire termination accepts solid conductors: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), max 2x (0.75–4 mm²). The maximum AC-1 rated cross-section is 2.5 mm². Environmental limits: operating temperature -25 to +60 °C, storage -55 to +80 °C, maximum altitude 2 000 m. Front and terminal protection is IP20, suitable for enclosed panel use.
Depth is 72 mm, height 57.5 mm. Screw terminals accept the listed wire sizes. Side-by-side mounting is permitted, so multiple contactors can be ganged without spacing gaps.
