Surge protective devices

Surge protective devices

Available in two models, these panel-mounted surge protective devices (SPDs) are designed for facilities with 3-phase, wye-configured systems that require surge protection for all seven modes in the AC distribution network. Both models have a parallel-operated design that includes metal-oxide varistors that are 40 mm in diameter, and EMI/RFI filter circuitry with high-voltage-rise capacitors for harmonic tolerance. The units can be flush- or surface-mounted, and they’re available with brackets that permit any type of installation, including flat or side mounting to studs. They feature a viewing window on the cover that enables users to verify the status of all modes, low-clamping and high-surge current performance, real-time diagnostics that monitor power and suppression status for each phase, LED indicators, and an audible alarm.
