The SPD II range of surge protectors are used for
transient surge protection of single and multi-phase power cir-
cuits at the main electrical panel. SPD IIIs are for the protection
of individual electrical devices. They provide common-mode pro-
tection (between each Line and Ground), with impulse discharge
capacity (Imax) 40kA for SPD II and 20kA for SPD III.
The SPD design is based on high-energy varistors (MOVs)
equipped with thermal disconnects and integral failure indica-
tors. A remote signaling contact for disconnection indication is
standard on each unit. For ease of replacement, varistors are
housed in pluggable modules with connections that are me-
chanically keyed to the base to prevent incorrect arrestor mod-
ule replacement.
Typical applications include low voltage distribution or protec-
tion of industrial control systems, equipment
assemblies and devices.
