Explosion Proof - Visual Signals
Visual Signaling Devices designed to meet US National Electrical Code (NEC) Article 500/501 Explosion-Proof designator to protect areas where the potential for gases or dust to explode exist in normal conditions (UL Class 1, Division 1). These products also meet less stringent requirements for hazardous location areas, such as UL Class 1, Division 2.
Explosion proof warning lights are available in either xenon strobe tube or LED configurations. Engineered and manufactured for installations in petrochemical facilities, offshore oil platforms, and oil refineries. UL listed and classified by the NEC as Class I, Div. 1 & 2, Groups C & D, Class II, Div. 1 & 2, Groups E, F, G, and Class III, Div. 1 & 2. They also meet NEMA standards 3, 4, 4X, 7CD, and 9EFG and are marine rated for use in salt water environments.
Design features include housing made of die cast high-strength copper-free aluminum alloy with a baked powder epoxy finish, stainless steel hardware, o-ring sealed pre-stressed glass globe with double-pitch acme threads for smooth assembly and ease of maintenance, and an optional guard which need not be removed for re-lamping.
