The 110 V DC coil means you need a DC supply for the pick-up and hold — verify your control transformer or power supply delivers clean DC at that voltage, because the coil's dropout threshold sits below 18 V and a saggy rail will drop it out mid-cycle.
Solid/stranded wire acceptance: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), max 2x (0.75–4 mm²) per terminal — spring-cage or screw terminals depending on variant, but this order code carries screw fixing.
Switching performance and thermal limits
Rated for 500 operations per hour at AC-1 (resistive), 420 at AC-3 (motor start/run), 130 at AC-4 (plugging/inching). The DC switching rates are lower — 250 at DC-1, 200 at DC-3 and DC-5 — reflecting the harder arc extinction on DC. Arcing time sits between 10 and 15 ms; the DC dropout delay is 80–100 ms, which matters if you're sequencing contactors in a safety circuit and need to guarantee the gap between drop-out and re-closure.
