The 1200 V blocking voltage means it handles the peak of a 600 VAC sine wave without breakdown — that's the margin that keeps the semiconductor from failing on line transients or switching surges. Because it's a zero-crossing SSR, it switches on near the voltage zero, which limits inrush into resistive or lightly inductive loads like heaters or lamp banks. ## Mounting and thermal reality This relay is designed for mounting on available cooling surfaces — it has no internal heatsink. The 90 A rating is only achievable with an adequately sized external heatsink or panel metal. In a typical DIN-rail enclosure, that means bolting the relay's base plate to a grounded metal backplate or a dedicated heatsink profile. ## Compliance documentation RoHS compliant since 15 January 2024.
