Its three normally-open instantaneous contacts switch pilot loads, signal feedback, or interlock circuits.
Switching capacity varies with voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, down to 1 A at 690 V. That's the load it can break across the contact gap — the 6 kV rated surge voltage means the contacts handle transient spikes common in inductive circuits without welding or arcing over. Contact reliability is specified at one incorrect switching operation per 100 million cycles at 17 V, 1 mA — that's the dry-circuit performance for low-energy signals like PLC inputs. Mechanical life of 30 million operations covers the typical panel lifetime.
Environmental tolerance — built for the nacelle or the panel
Shock resistance: 10g for 5 ms and 5g for 10 ms. That covers the vibration and thermal cycling inside a wind turbine nacelle or a conveyor line cabinet.
Solid wire terminals accept 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², and 2x 4 mm². That's two conductors per clamp — useful for daisy-chaining control voltage or looping feedback signals without extra terminal blocks. The IP20 front protection means the contactor is touch-safe on the front face once installed in an enclosure.
