SurgeX PF-420 Branch Circuit Power Filter, 120V

Product Overview

The SurgeX PF-420 is a whole-room branch circuit surge protector installed at the service panel, sub-panel, or load center rather than at individual outlets. It's built for AV integrators who need guaranteed surge protection across an entire room or building branch — conference centers, broadcast facilities, and mission-critical AV installs — instead of relying on protection at each rack or display.

Product Description

Point-of-use surge protectors only cover what's plugged into them; a branch circuit device like the PF-420 protects everything downstream of the panel it's installed at. The PF-420 is configured for (4) 20A/120V circuits feeding an 80-amp load center, giving whole-room coverage for a space with multiple AV racks, displays, or a full control room on a shared electrical branch. It's built in a NEMA magnetic shielding steel enclosure that meets code for installation at the service entrance, sub-panels, and inside ceiling plenums — a common requirement in commercial and government AV projects where the electrical contractor needs a listed enclosure. Advanced Series Mode surge elimination and power conditioning handle the electrical side: surge energy is eliminated at the source without producing the ground contamination or common-mode disturbances that come with older MOV-based protection. An all-mode, impedance-tolerant EMI/RFI filter further cleans the branch circuit, which matters for audio and video signal integrity in rooms with a lot of switched-mode power supplies on the same circuit. Because the PF-420 protects at the panel rather than the outlet, it's typically specified during electrical rough-in on new construction or a full AV room renovation, coordinated with the electrical contractor rather than installed by the AV integrator alone.

Key Features

• Whole-Room Surge Protection — Protects every downstream circuit from a single panel-level installation.
• NEMA Magnetic Shielding Steel Enclosure — Meets code for service entrance, sub-panel, and ceiling plenum installation.
• Advanced Series Mode Surge Elimination — Eliminates surge energy without ground contamination or common-mode disturbances.
• All-Mode Impedance Tolerant EMI/RFI Filter — Reduces electrical noise across the branch circuit for cleaner AV signal performance.
• 80 Amp Load Center — Supports four 20A/120V circuits for multi-rack or multi-room branch protection.

Typical Applications

• Government space
• Commercial meeting space
• Broadcast studio
• Auditorium
• Multi-purpose room

Technical Specifications

Frequently Asked Questions

Is the PF-420 compatible with a standard electrical service panel?
Yes, it's built in a NEMA magnetic shielding steel enclosure rated for installation at the service entrance, sub-panel, or load center.

Who typically installs the PF-420?
Because it's a panel-level device, it's usually installed by the electrical contractor during rough-in, coordinated with the AV integrator's project scope.

Does it protect equipment plugged in downstream automatically?
Yes. Once installed at the panel, every circuit downstream of the PF-420 receives Advanced Series Mode surge protection without additional point-of-use devices.

Can it be installed in a ceiling plenum?
Yes, the enclosure is rated for ceiling plenum installation in addition to service entrance and sub-panel locations.

What warranty does SurgeX provide?
SurgeX publishes its current warranty terms on ametekesp.com; contact Creation Networks for the specific coverage period applicable to this model.

What support does Creation Networks provide during installation?
Creation Networks can coordinate with your electrical contractor on panel-level surge protection specification as part of a project scope of work.
