SED57-H Series Explosion-Proof Induction Lamps
Engineered for Zone 1/2 gas and Zone 21/22 dust environments, the SED57-H series delivers energy-efficient, maintenance-free lighting for oil refineries, chemical plants, and marine facilities. Its die-cast aluminum housing with electrostatic coating and tempered borosilicate glass ensures IP66/WF2-rated durability against corrosion, impacts, and thermal stress. Features include a 99.99% pure anodized aluminum reflector for optimal light output, high-efficiency induction lamps (40-80W) with instant start-up and low light decay, and electronic ballasts with surge protection (PF≥0.95). Certified to Ex db IIC T6 Gb/Ex tb IIIC T80°C Db, it offers cage-type terminals for vibration-resistant wiring and versatile mounting (ceiling, wall, flange). Ideal for energy-saving retrofits in harsh T1-T4/T3 conditions.
