Electrical Rating:

UL models: 5 A @125/250 VAC. CSA, ATEX and IECEx models: 5 A @ 125/250 VAC (V~); 5A 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″ (457.20 mm) long. ATEX/CSA / IECEx models: terminal block.

Upper Body:

Brass or 303 stainless steel.

Conduit Connections:

Process Connection:

1/2″ (12.70 mm) male NPT or 1/2″ (12.70 mm) male BSPT on models without a tee.

Mounting Orientation:

Switch can be installed in any position but the actuation/deactuation flow 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 flow models are field adjustable in the range shown. See set point charts on Catalog page.
