Description Introducing compact, durable, easy to use the Explosion Proof Stainless Steel Vertical Float Switch APG FS-400 Series is certified for use in Class 1 Division 1, Division 2, Class 2 Division 1, Division 2, Class 3 hazardous locations. Backed up with NFC and NEMA 4x approvals. With all stainless steel wetted materials, operating temperatures up to 500° F, and a 100 W switch, the series FS-400 float switch fits a wide range of applications in two standard configurations. Features: Class 1 Division 1/2 Class 2 Division 1/2 Class 3 NEMA 4x NSF 169 certified Compact size Reliability / long switch life Shock resistive construction Switch rated for 100 W Can be used in a wide range of liquids Operating temperatures up to 500° F (260° C) CSA Explosion Proof (Standard Temp) and General Use (High Temp) Vertical mounting 316L SS material Made in the USA Compact Size: From the top of the mounting threads to the bottom of the stem, the FS-400 is less than 3.5″ long, and the float is just over 2″ wide Temperature Ranges: The FS-400-S has an operating temperature range of -40° to 368° F (-40° to 187° C), and the FS-400-HT extends that range to -40° to 500° F (-40° to 260° C) Certifications: All FS-400 switches are NSF 169 certified User Reversible Operation: FS-400 float switches come standard with Normally Open operation. The e-clip at the bottom of the stem is easily removed to change to orientation of the float, changing the switch operation to Normally Closed.
