Celduc Semiconductor SGB963360E Solid State Relay

The Celduc SGB963360E Solid State Relay is a three‑phase SSR that switches all three AC lines in a single compact module, with each phase rated 35 A (3×35 A thyristors) and a line‑voltage range of 24–600 VAC. It blocks up to 1,200 V peak and accepts a DC control signal of 10–30 V, enabling safe, galvanically isolated control of industrial loads. The device uses synchronous zero‑cross switching to minimize inrush and EMI on resistive three‑phase circuits, and carries an I²t rating of 882 A²s for transient surge handling. Its footprint measures 100 × 75.15 × 46 mm, with mounting holes spaced 47.5 mm and an enclosure width of about 45 mm, designed to be mounted on a heatsink to achieve nominal current. The SGB963360E is typically used for resistive three‑phase loads such as heating elements or other non‑inductive loads, where reliable solid‑state switching across all three phases is required without mechanical wear.
