Gould EQ-9481 - 150A, 4-Pole, Circuit Breaker

The Gould EQ-9481 150A, 4-Pole Circuit Breaker is built to deliver dependable overcurrent protection in demanding electrical environments. Designed for 3-phase systems with a neutral, this four-pole configuration ensures all poles trip together, enhancing safety and guarding wiring, components, and downstream equipment from overloads and faults.

Why the 4-Pole design matters

In industrial and commercial power distribution, a 4-pole breaker like the EQ-9481 provides synchronized disconnection of all live conductors. This minimizes the risk of dangerous residual current, reduces arc-flash exposure during maintenance, and simplifies compliance with safety standards in complex panel systems.

Key features that set this Gould breaker apart

• Current rating: 150A — robust protection for feeders, motor circuits, and distribution lines without nuisance tripping in normal operation.
• Poles: 4-Pole — ideal for 3-phase systems with a neutral, enabling comprehensive shutdown of all conductors when protection is triggered.
• Breaker type: Circuit Breaker — engineered for quick, reliable interruption during overcurrent events, preserving equipment and reducing downtime.
• Versatile installation — compatible with Gould panelboards, switchboards, and control panels, making it a practical choice for a range of installations.
• Industrial, commercial, and OEM readiness — designed to meet the demands of distribution panels and motor control centers where dependable protection and safe operation are critical.

Ideal use cases

• Industrial facilities with 3-phase motor drives and complex distribution panels
• Commercial electrical rooms requiring reliable protection for feeders and critical circuits
• OEM equipment enclosures and control panels where a robust, four-pole protection solution is needed
• Motor control centers and switchgear assemblies that demand fast, clean isolation of all conductors

What problems it solves

The EQ-9481 delivers precise overcurrent protection to prevent wiring damage, equipment burnout, and fire risk from short circuits or overloads. By disconnecting all poles simultaneously, it minimizes fault stress on downstream components and supports safer maintenance procedures in panel installations.

Installation and compatibility notes

Designed for Gould distribution systems, this 4-pole circuit breaker integrates into standard Gould panelboards, switchboards, and control panels. Its 150A rating makes it suitable for main or feeder protection in mid- to high-load applications, helping you simplify panel design and enhance system reliability.
