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 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.
The DIN-rail mounted SPDs are available in a wide range of operating voltages and include solar applications. They are ideal for:
SURGE PROTECTION DEVICES – TYPE 2
SPD2 SERIES
FEATURES BENEFITS
Capability to clamp and withstand high-energy transients Ensures low-residual voltage during high-energy surge events and higher nominal discharge current
to prevent disruption, downtime, and degradation or damage to equipment
UL and VDE-IEC compliant in single part number One component can be utilized globally, reducing inventory needs and simplifying allocation of parts
Interlocking tab mechanism Secures module to withstand vibration
SPD type and voltage-coded plug-in module Prevents specific SPD/voltage module from being plugged into wrong base. Eliminates risk of
improper protection
No additional overcurrent protection devices required in UL applications Reduces the number of components and costs required for protection
Compact footprint Increases panel design flexibility
Visual life indicator Quick visual determines module replacement status to avoid loss of protection
Pluggable modules Fast and simple to replace, minimizing maintenance and downtime. No tools required
Thermal protection Eliminates catastrophic failure
IP20 protection rating Finger-safe design increases worker protection

Surge Protection Devices
Class II/Type 2/Type 1 CA Pluggable Single-Pole
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.
The surge protection devices for the 1+0 configuration are
available for 60 V to 600 V nominal voltage sub-distribution
board applications.

Description
Surge protective 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.
The surge protective devices for solar string box and inverter
applications are available in 1100 and 1500 V dc in the 3+0
configuration.
