Pressure Switch for Air DL Application DL air pressure switches provide accurate, reliable supervision of air pressure for both industrial and commercial combustion systems, boilers, HVAC systems and a wide variety of other applications.

The DL air pressure switch controls rising and falling pressure ensuring a set limit value.

Specifications

Ambient, air and
storage temperature:
-40 °F to 140 °F (-40 °C to 60 °C)
Switching capacity: 30 – 240 Vac, I = 5 A resistive or 0.5 A inductive (cos φ = 0.6),
"G" models: use at ≤30 V rate 0.1 A resistive or 0.05 A inductive (cos φ = 0.6).
Short circuit protection: Use 8 A quick-acting fuse
Material of Construction: All Kromschroder diaphragm actuated pressure switches are constructed of special high quality molded plastic. Diaphragms are nitrile rubber. The DL..ET enclosure is rated for IP10/NEMA 1 general purpose. The DL..AT switches have an NEMA 3/IP54 rating.
Electrical Connections: "E" Models: ¼″ (6.3 mm) spade-type wiring terminals.
"A" Models: Screw terminals for 18 – 14 AWG wire, ½″ RP conduit connector.
Pressure Connections: "E" Models: Hose barb for 5/32″ (4.3 mm) ID tubing.
"A" Models: Hose barb for 5/32″ (4.3 mm) ID tubing.
Additional ¼″ RP female connection for high pressure side of switch.
