The spring-loaded terminals accept 2x (0.5 to 2.5 mm²) without core-end processing or 2x (0.5 to 1.5 mm²) with ferrules, and the equivalent AWG range is 2x (20 to 14).
The AC-15 rating of 1 A at 690 V tells you this switch can handle inductive loads — contactor coils, solenoid valves — at higher voltages without welding contacts. For DC switching, the 24 V rating is 10 A (resistive) or 6 A (likely inductive, per the at-24-V entry), dropping to 0.3 A at 220 V DC and 0.26 A at 600 V DC. That DC derating is steep: if you're switching a DC coil at 110 V, you're limited to 1 A. The mechanical life is 10 million switching cycles typical, so this block outlasts most contactors it rides on.
Integration notes
Snap-on mounting to a DIN rail, size S00. The block is 36 mm wide, 47.7 mm deep, and 41.5 mm tall — it shares the same footprint as the 3RH2 contactor relay series it's designed for. Two NC contacts are instantaneous (no leading or lagging delay), and one NO contact is also instantaneous. The leading contact count is zero, so all contacts switch simultaneously. Front-side protection is IP20 — suitable for enclosed panels, not for washdown environments.
