<h2>Overview</h2>
<p>The Gaumer Process SSRL48D100 is an industrial-grade solid state relay engineered for high-reliability DC-to-AC switching in process heating and electrical control systems. This relay accepts DC input control signals in the 4–32V range at 48A and switches 480V AC loads up to 100A continuous (AC51 rating) or 30A for more demanding AC-3a duty cycles. The compact IP-rated design integrates readily into panel-mounted and DIN-rail applications.</p>
