Celduc Relais Solid State Relays SO967440

The SO967440 is a single-phase solid state relay designed for resistive loads (AC-51) with a 24 to 600 VAC output rating and a 90 A nominal current. It features back-to-back thyristors with TMS2 technology, a zero-crossing input for 3.5 to 32 VDC control, and a green LED indicator. The relay includes input and output overvoltage protection, IP20-rated terminal flaps, and requires mounting on a heatsink. It complies with IEC/EN60947-4-3, IEC 60335-1/VDE0700-1, and cURus standards. The device has an I²t rating above 6000 A²s for MCB protection, a thermal resistance of 0.3 K/W, and operates from -40°C to +100°C. It measures 80 g in weight and supports mains frequencies from 0.1 to 200 Hz.
