Polyphaser Power Mains In-Line Type Line Surge Protector

IS-IL Series


Where outside originating line surges are a problem and they must be shunted and filtered to protect sensitive electronic equipment.
bulletSingle, bi and three phase
bullet120, 208, 240, 400 and 480Vac
bulletBuilt-in redundancy - dual stages per phase with pi-network, low pass filtering
bulletSurge energy is shunted to ground, not to neutral
bulletNeutral protection for single earthed neutral sites
bulletFront panel circuit breaker indicators
bulletRemote local status dry contacts
bullet100 and 200A load currents per phase
bulletProtectors individually circuit breakered won't interrupt load power
bulletField replaceable protection blocks/circuit breakers if needed
bulletNRTL UL 1449 listed NRTL/C LR#106164-3
bulletNot weather resistant
