Overvoltage Protection Surge-Trap® SPD Surge-Trap Pluggable SPD

About the Surge-Trap Pluggable SPD


Like its modular predecessor, the Surge-Trap Pluggable SPD offers fail-safe protection and mounts easily on a DIN-rail to safeguard critical electrical system components from the harmful effects of transient overvoltages. Its IP-20 grade “finger-safe” design makes it easy to replace upon failure without touching the base or the hassle of rewiring. Plugs are available in various voltage configurations, with photovoltaic configurations also available.


With features for both visual status and remote signaling indication, the Surge-Trap Pluggable SPD suits system voltages from 120V to 600V and MCOV rated 180V to 550V. It has a 200kA short circuit current rating (SCCR) and 20kA 8/20µs surge capacity (In) rating per mode. Agency approvals include UL 1449, 3rd Edition, ANSI/IEEE C62.41 and IEC 61643-1 Type 2. Multiple configurations are available, with DIN-rail or direct panel mounting.
