SPD II & III – AC Surge Protector
The SPD II range of surge protectors are used for
transient surge protection of single and multi-phase power circuits at the main electrical panel. SPD IIIs are for the protection
of individual electrical devices. They provide common-mode protection (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 indicators. 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 mechanically keyed to the base to prevent incorrect arrestor module replacement.
Typical applications include low voltage distribution or protection of industrial control systems, equipment
assemblies and devices.
