Surge Protective Device Catalog
Consult this catalog when choosing a Type 1 or Type 2 surge protective device and when using a Littelfuse SPD to replace one made by another company.
DIN Rail surge protective devices (SPDs) are engineered to snap or bolt easily onto nonconducting rails or supports inside equipment cases. Like all Littelfuse SPDs, DIN Rail devices safeguard electronic components against damage from transient voltage surges, especially those occurring during equipment startup and shutdown. Installing SPDs brings equipment into compliance with electrical codes, limits downtime, and reduces maintenance costs.
