Ferraz Shawmut Surge-Trap pluggable surge protective device
By Anthony Capkun
Ferraz Shawmut introduced its new Surge-Trap pluggable surge protective device (SPD), which meets requirements for both UL 1449 (3rd ed.) and IEC 61643. Like its modular predecessor, the pluggable SPD features TPMOV technology and is a “no-fuse” SPD that doesn’t require the use of additional overcurrent protection. It also offers IP-20 grade finger-safe protection and mounts easily on a DIN-rail to safeguard critical electrical system components from the harmful effects of transient overvoltages. The Surge-Trap pluggable SPD product line offers plugs with various voltage configurations that are easily replaceable upon failure without touching the base or the hassle of rewiring. The SPD’s features include a visual indicator, easy installation, fail-safe design, mechanical coding and remote monitoring. Photovoltaic configurations are also available.
