No-fuse, fail-safe surge protection device

Mersen has introduced the Surge-Trap Pluggable STP-50 Series Surge Protective Device (SPD). The STP-50 joins Mersen’s STP-75 Series Pluggable SPDs and ST Series Monobloc SPDs to provide engineers a wide range of SPDs to meet the diverse specifications and requirements of many industries. Mersen’s STP-50 Series is a no-fuse, fail-safe surge protective device with a 50kA short circuit rating, suitable for most industrial control panels. Featuring Mersen’s TPMOV technology inside, there is no need for additional overcurrent protection. A reversible chassis allows cable entry from top or bottom and a remote indicator provides status to critical control circuitry. Replaceable surge modules feature mechanical coding to avoid replacement errors. Both STP-50 and STP-75 Pluggable SPDs are designed to provide safe and reliable performance in high-risk environments. Both SPDs feature a new enhanced base with a tool-less DIN-rail clip for easy installation. The STP-50 Series comes with a 5-year warranty and is intended for use on a wide range of low-voltage applications inside appropriate enclosures.
