Looking for a fail-safe surge protection device? National Fuse Products is excited to introduce Mersen’s latest addition – the Surge-Trap Pluggable STP-50 series. The Mersen STP-50 Series is a no-fuse, fail-safe surge suppressor with a 50kA short circuit rating, suitable for most industrial control panels.
 
With Mersen’s TPMOV technology inside, there is no need for additional over current protection.  A reversible chassis allows cable entry from top, or bottom and a remote indicator provides status to critical control circuitry.
 
The STP-50 series is designed with a new enhanced base and a DIN-rail clip for easy installation. The STP-50 Series comes with a 5-year warranty. Applications include industrial control panels, water treatment plants, smart grid and LV metering, and intelligent transportation systems. National Fuse is a licensed Mersen distributor.
