Littelfuse Surge Protection Devices Catalog
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 are sometimes caused by an indirect lightning strike. But the majority—60 to 80%*—are caused by equipment being turned on or off within a facility. Littelfuse surge suppressors are ideal for applications in power distribution, HVAC or medical equipment, industrial controls, electrical loads, computers, and communication devices.
