PSP1 Plug-In Special Purpose Supervisory Switch

PSP1 plug-in switches are special application supervisory switches designed for applications where no other type of listed valve supervisory switch can be installed.PSP1 plug-in switches are to be used on non-rising stem gate valves and ball and angle valves. The unit is approved for Class A and Class B circuits.PSP1 switches consist of a rugged rain tight metal housing. With a NEMA 3 rated housing and water-resistant cord, PSP1 switches may be used in either indoor or outdoor applications. These switches feature a 360° versatile mounting design and an adjustable length cord which allows more freedom to install the unit at the most desirable alignment angle. The switches employ a supervisory cord which, when pulled out, closes a set of normally open contacts. A lockout feature prevents reinsertion of the cord until the cover is removed, and the unit is reset. Removal of the cover or cutting of the cord results in an open circuit.
