Krom Gas pressure switch DG 10U-3
Application DG gas pressure switches provide accurate, reliable monitoring of gas and airpressures for industrial and commercial applications. They are suitable for naturalgas, LP, bio-gases and air. UL listed and FM approved, they can be used as high and low gas and low airproving switches in combustion supervisory systems.
SpecificationsOperating LimitsAmbient and gastemperature range: -40° F to 140° F (-40° C to 60° C).Maximum storagetemperature: 158° F (70° C).Electrical DataSupply voltage: 30 – 240 Vac; 50/60 Hz, Special "G"models available for voltages below30 Vac.Switch contactrating: 5 A resistive or 0.5 A inductive(cos diam. = 0.6). For “G” models, 0.1 Aresistive or 0.05 A inductive(cos diam. = 0.6).Short-circuitprotection: use 8 A quick-acting fuse.
Materials of ConstructionDG pressure switch covers are high quality injection-molded plastic.Switch housings are glass fiber-reinforced plastic and pressure die-cast aluminum alloy. Diaphragms are nitrile rubber. Enclosures are NEMA 3 (IP 54).
Electrical and Pressure ConnectionsScrew terminals for a maximum wire gauge of #14.1/2" NPT conduit connection.1/4" NPT female connections (2) for pressure (high differential) side of switch.1/8" NPT female connection for suction (low differential) side of switch.1 1/32" (9 mm) diameter test hose fitting on pressure (high differential) side of switch.
