Specifications

Operating Limits

Ambient and gas temperature range: -40° F to 1400 F (40° C to 60° C)  
Maximum storage temperature: 158° F 70° C).
Electrical Data

Supply voltage: 30—240 Vac; 50/60 Hz,
Special “G” models available for
voltages below 30 Vac.

Switch contact rating: 5 A resistive or
0.5 A inductive (cos ( 0.6). For “G”
models, 0.1 A resistive or 0.05 A
inductive (cos ( 0.6).

Short-circuit protection: use 8 A quick-
acting fuse.
Materials of Construction
DG 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 Connections
Screw 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.
