Power Switching & Controls For Business-Critical ContinuityTM Edco™ H Series Telecom/Punch Block Primary/Secondary Protection The Edco H Series modules are ultra high speed fused solid state dual listed Primary (UL 497) and Secondary (UL 497A) protectors for KEY/PABX systems. The units are available in two different clamping voltages. The Edco H Series is constructed with solid state silicon foldback technology, polyswitch resettable fuses — PTCs — and failure fuses. The protective elements switch from the normal high-impedance state to a low-impedance state upon a detection of a surge, then switch back to high impedance after the surge has passed. The Edco H Series single pair modules fit onto a standard Edco MI-50 split block and replace bridging clips. In addition, these modules require the Edco MGB Ground Rail for each Edco MI-50 block used.
