Datasheet Summary
Powered by GS/AI

The ES325B3AD is a 3-pole double-throw electromechanical relay built to MIL-PRF-83536, designed for severe environmental applications in rail, aerospace, and ground vehicles. It features a hermetically sealed, non-corrosive enclosure and a balanced force design for extended contact life. The relay has dimensions of 26.0 mm × 26.0 mm × 25.7 mm and weighs 82 grams. It operates with a 12 VDC coil, has a 25 A contact rating for resistive and inductive loads at 115/200 Vac, and supports switching operations up to 400,000 mechanical cycles. The operating temperature range is -70°C to +125°C, with a maximum operate time of 15 ms at +25°C. The terminal configuration is gold plated, and it includes internal voltage suppression.
