Littelfuse Surge Protection Modules
Globally-compliant, cost effective surge protection devices.
The Type 2 Surge Protection Devices have higher nominal and total discharge current protection which helps limit transient overvoltage to equipment mitigating costly damage and downtime.
Surge protection devices (SPDs) provide equipment protection from transient overvoltage events lasting micro-seconds, by limiting the overvoltage to the equipment during these events reduces costly damage and downtime.
