SurgeX PF-420 | Four-Circuit Advanced Series Mode Surge Eliminator

The SurgeX PF-420 is a professional-grade, hardwired branch-circuit surge eliminator designed to protect high-performance audio systems, dedicated home theaters, and sophisticated AV installations. Featuring SurgeX's proprietary Advanced Series Mode® surge elimination technology, the PF-420 delivers non-sacrificial surge protection and AC line noise filtration at the electrical distribution level, before power reaches connected equipment.

Engineered for demanding residential and commercial installations, the PF-420 provides protection for four independent 120V, 20-amp branch circuits, supporting a combined nominal circuit capacity of 80 amps. Its centralized architecture makes it particularly well suited for custom theaters, high-current amplification systems, equipment rooms, and integrated audio/video environments.

Advanced Series Mode® Surge Elimination

Unlike conventional surge suppressors that rely on sacrificial metal oxide varistors (MOVs), SurgeX Advanced Series Mode technology is designed to repeatedly absorb and eliminate damaging surge energy without gradual component degradation.

The PF-420 provides comprehensive electrical protection while maintaining the integrity of the incoming AC supply.

Key Benefits

• Advanced Series Mode non-sacrificial surge elimination

• Four independently protected 120V, 20A branch circuits

• Protection against repeated high-voltage surge events

• Integrated EMI/RFI noise filtration

• Hardwired protection at the branch-circuit level

• Heavy-duty steel enclosure for permanent installation

Engineered for High-End Audio & Home Theater

Modern high-performance audio and video systems often require multiple dedicated electrical circuits to support demanding amplifiers, powered subwoofers, projection equipment, processors, and source components.

The SurgeX PF-420 protects these circuits from a centralized location, providing a practical solution for installations where conventional plug-in surge protectors are insufficient or undesirable.

Ideal applications include:

• Dedicated two-channel listening rooms

• High-end home theaters and private cinemas

• Multi-amplifier and high-current audio systems

• AV equipment racks and technical rooms

• Custom residential automation installations

• Commercial audio/video systems

Technical Specifications

Professional Installation

The SurgeX PF-420 is intended for permanent integration into a building's electrical infrastructure. Installation must be performed by a qualified electrician in accordance with applicable electrical codes and manufacturer requirements.

For new construction, dedicated home theater circuits, or major audio system upgrades, branch-circuit surge protection offers a centralized approach to safeguarding valuable electronics.

The Grid HiFi provides high-end audio, home theater, and custom AV system design with electrical infrastructure considerations integrated into the overall system planning process.
