Electrical
Rating
UL models: 5 A @125/250 VAC. CSA, ATEX and IECEx models: 5 A @ 125/250 VAC (V~); 5 A res., 3 A ind. @ 30 VDC
(V
). MV option: .1 A @ 125 VAC (V~). MT option: 5 A @125/250 VAC (V~). [MT option not UL, CSA, ATEX or IECEx].
Electrical Connections UL models: 18 AWG, 18˝ (460 mm) long. ATEX/CSA /IECEx models: Terminal block.
Upper Body Brass or 303 SS.
Conduit Connection 3/4˝ male NPT standard, 3/4˝ female NPT or M25 with BSPT option on junction box models.
Process Connection 1/2˝ male NPT or 1/2˝ male BSPT on models without a tee.
Mounting
Orientation
Switch can be installed in any position but the actuation/deactuation ow rates in the charts are based on horizontal pipe
runs and are nominal values.
Set Point
Adjustment
Standard V6 models none. Without tee models vane is trimmable. Low ow models are eld adjustable in the range shown.
See set point charts.
Weight 2 to 6 lb (.9 to 2.7 kg) depending on construction.
Options not Shown Custom calibration, bushings, PVC tee, reinforced vane, DPDT relays.
Agency Approvals ATEX, CE, CSA, IECEx, KTL, UL.
