Eaton ISOBAR4ULTRA – 4‑Outlet Surge Protector 3330 J

Overview

The Eaton ISOBAR4ULTRA is a high‑capacity AC surge protector designed to defend sensitive electronics against transient voltage surges, spikes, and line noise on 120 VAC mains circuits. It is deployed by IT infrastructure teams, AV integrators, and facilities engineers where branch‑level power protection is required for network workstations, telecom systems, or peripheral equipment.

This unit provides four NEMA 5‑15R outlets arranged into isolated filter banks to minimize noise interaction and support bulky transformer plugs without blocking adjacent receptacles. It features network‑grade surge suppression rated at 3330 joules and a resettable 12 A circuit breaker integrated into the lighted on/off switch for overload protection.

The built‑in 6 ft (1.8 m) AC power cord with a right‑angle NEMA 5‑15P plug enables flexible placement from a standard wall receptacle while minimizing cord profile in tight spaces. A rugged all‑metal housing with keyhole mounting tabs supports bench, wall, and under‑desk rack shelf deployments.

Diagnostic LEDs provide real‑time indication of surge protection status, line fault, and power presence, aiding technicians in verifying protection health during installation and maintenance. The isolated filter banks also reduce electromagnetic (EMI) and radio‑frequency interference (RFI) that can degrade performance of connected equipment.

A practical deployment is protecting edge networking gear, desktop workstations, or point‑of‑sale terminals in branch office closets where a PDU is not feasible. This model is not intended for direct connection to UPS output receptacles that provide already conditioned power, or for loads exceeding the 12 A circuit breaker rating.
