Product details

Main and auxiliary/control circuits use screw-type terminals. Solid conductors accepted: 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²). Stranded: 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²). AWG equivalents for main contacts: 2x (14 to 10). The auxiliary switch is transverse design and the product extension for auxiliary switch is available.

Shock resistance: 25g for 11 ms. Power dissipation in hot operating state under AC conditions: 5.5 W. Maximum operating frequency in AC-3 duty: 15 operations per hour.

Listed as current production (active lifecycle stage). Substance prohibition date per RoHS/REACH compliance: 01.05.2012, indicating the part meets the EU substance restrictions effective from that date. No ground fault detection; phase failure detection is included.
