SurgeX SX-20NE-RT Branch Circuit Surge Eliminator, 120V

Product Overview

The SurgeX SX-20NE-RT is a single-circuit branch surge protector installed at the service panel, sub-panel, or load center to protect one 20A/120V circuit rather than an individual outlet. It's built for AV integrators who need guaranteed surge protection at the panel level for a single room or branch — a smaller conference room, a single-rack install, or a dedicated circuit feeding sensitive AV equipment.

Product Description

Point-of-use surge protectors only cover what's plugged into them; a branch circuit device like the SX-20NE-RT protects everything downstream of the panel it's installed at. The SX-20NE-RT is configured for a single 20A/120V circuit, making it the right-sized option when a full multi-circuit load center like the PF-420 is more capacity than a project needs — for example, a single dedicated AV circuit in a smaller conference room or huddle space. 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 circuit, which matters for audio and video signal integrity on circuits shared with switched-mode power supplies. Because the SX-20NE-RT protects at the panel rather than the outlet, it's typically specified during electrical rough-in on new construction or a room renovation, coordinated with the electrical contractor rather than installed by the AV integrator alone.

Key Features

• Single-Circuit Branch Protection — Protects one 20A/120V circuit from a 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 on the circuit for cleaner AV signal performance.

Typical Applications

• Huddle room
• Conference room
• Government space
• Commercial meeting space
• Multi-purpose room

Frequently Asked Questions

Is the SX-20NE-RT 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 SX-20NE-RT?
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.

How does this differ from the PF-420?
The SX-20NE-RT protects a single 20A/120V circuit, while the PF-420 covers four circuits on an 80-amp load center — the SX-20NE-RT is the right fit when only one dedicated circuit needs branch-level protection.

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.
