Celduc Relais Solid State Relays SO963940

The SO963940 is a single-phase zero-cross solid state relay designed for resistive loads, with an output rating of 24 to 600VAC at 40A RMS and an input control range of 18 to 280VAC/DC. It features back-to-back thyristors with TMS2 technology, output overvoltage protection via TVS diodes, and a green input LED. The relay is mounted on a heatsink, has IP20 protection via removable terminal flaps, and weighs 80 g. It complies with IEC/EN60947-4-3, IEC 60335-1/VDE0700-1, and cURus standards. Input immunity meets EN61000-4-4 and EN61000-4-5 at 2kV, and output insulation is rated at 4000 VRMS. Thermal resistance between junction and case is 0.55 K/W.
