Surge Protective Devices SPD2 SERIES OVERVIEW Littelfuse Type 2 Surge Protection Devices (SPDs) for branch circuits safeguard components from transient overvoltage or surges by limiting the fault current to a load or the unit being protected. Surges may be caused by an indirect lightning strike but, the majority—sixty to eighty percent*—are caused by equipment being turned on or off within a facility. These surges damage components costing money to repair or replace as well as create unplanned downtime resulting in unfulfilled orders, missed deadlines, unreliable systems and/or dangerous situations....

Surge Protective Devices SPD2 1P+0 SERIES Class II/Type 2/Type 1 CA Pluggable Single-Pole Pluggable RC Connector Description Surge protection devices (SPDs) provide equipment protection from transient overvoltage events lasting micro-seconds. By limiting the overvoltage to the equipment during these events, costly damage and downtime can be mitigated. Visual Life Indicator The surge protection devices for the 1+0 configuration are available for 60 V to 600 V nominal voltage sub-distribution board applications. Features & Benefits FEATURES BENEFITS Capability to clamp and Ensures low-residual...
