Heavy-Duty 30mm LED Red Pilot Light In Industrial Malleable Iron Box (malleable iron box has 3/4" conduit hubs) Pilot Devices : 30mm Hazardous Location : Pilot Lights Our 30mm H-Line pilot lights, when utilized with our LED lamps provide leakage protection, long-lasting life and high quality with tremendous resistance to shock and vibration. Our reflection technology and state-of-the-art LED lamps improve visibility from all angles. c3controls LED lamps last 100,000 hours ? that?s 11.4 years! Combine these LEDs with our full voltage or resistor packages for optimum durability. All c3controls 30mm H-Line operators are UL Listed and are rated Type 4/4X as standard for watertight and corrosion resistance. In addition, operators are also listed for Type 1, 2, 3, 3R, 12 and 13, and meet global standards requirements. Product Features Full voltage, resistor, and dual input remote test light units in a wide range of voltages. Light modules come with various lens color options and are available in incandescent, neon, or our LED lamps with leakage protection. Rugged LexanTM lenses for improved visibility and resistance to high impact for reliable performance, even in high ambient temperatures. Operators come standard with a polyester clamp ring, although optional aluminum clamp rings are available. #6 stainless steel terminal screws with self-lifting captive wire clamps accommodate #22 through two #12 AWG wires (0.5-4mm2) per terminal. All frictional parts are molded with an internal self-lubricant to provide outstanding wear without troublesome greases used by others. Our seal is infused with a coating to eliminate cracking when exposed to harsh conditions, and acts as a light reflector because it is white which increases light output and improves visibility from all angles. Manufactured with industrial grade plastics for strength and less weight, the tough polyester construction provides electrical insulation, resists corrosion, and rejects moisture. All metal parts are nickel-plated for superior corrosion resistance.
