Celduc Relais Solid State Relays SO963440

The SO963440 is a single-phase zero-cross solid state relay designed for resistive loads (AC-51) with an output rating of 24 to 600 VAC at 40 A rms. It features back-to-back thyristors with TMS2 technology, an input control range of 3.5 to 32 VDC, and a green LED indicator. The device includes integrated input and output overvoltage protection, IP20 terminal protection via removable flaps, and a thermal resistance of 0.55 K/W requiring mounting on a heatsink. It complies with IEC/EN60947-4-3, IEC 60335-1/VDE0700-1, and UL508 (cURus) standards, offering 4000 Vrms isolation between input and output, and operates from -55°C to +100°C ambient temperature. Weight is 80 g.
