Product details

It provides 2 normally-open and 2 normally-closed instantaneous auxiliary contacts, with no leading, delayed, or lagging switching elements in this variant. Rated operational current at AC-12 (resistive load) is 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. These are the per-contact switching limits across the voltage range; the 10 A AC-12 figure is the maximum for the contact set.

Wire capacity covers solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and 2x 4 mm².

Shock resistance is rated at 10g for 5 ms and 5g for 10 ms, which covers most industrial vibration profiles for panel-mounted gear.
