Celduc Semiconductor SO889060 Solid State Relay

The Celduc SO889060 is a high-current, single-phase solid-state relay (SSR) rated for 125 A load current and designed to switch 24–690 VAC loads. Its input control ranges from 3.5 to 32 VDC and it uses a SPST-NO (1 Form A) output, all packaged in the SO8 form factor. The module features zero-cross switching to minimize EMI on energizing AC loads, a peak off-state voltage up to 1,600 V, and an I2t rating of 22,000 A²s, providing robust surge handling. It carries global certifications including UL/cURus, UKCA, CSA, CE, VDE, and EAC, and is rated with an IP20 enclosure, suitable for control cabinets and industrial environments. Typical applications include controlling heating elements and other mains-powered loads in automation systems where high current and isolated DC control are required, offering seamless interfacing with 3.5–32 VDC control signals while isolating the control circuitry from the AC load.
