Eaton BRH320 - 20 A, 240 V, 3-Pole Plug-In Circuit Breaker | AmpState

The Eaton BRH320 is a 20 A, 240 V, 3-pole plug-in molded case circuit breaker designed for reliable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built to slot into compatible OEM panels, this device blends quick installation with precise protection, making it a smart upgrade or replacement wherever clean, dependable power management matters.

• Fast plug-in connection: Enables rapid installation or replacement, minimizing downtime during panel servicing or upgrades.
• Thermal-magnetic trip unit: Delivers stable, repeatable protection by combining overload protection (thermal) with instantaneous short-circuit interruption (magnetic) for reliable performance under varying conditions.
• 3-pole design for 240 V systems: Ideal for 3-phase applications and multi-pole protection schemes in commercial and light industrial environments, while still suitable for residential panelboards in some configurations.
• OEM-compatible: Engineered to be compatible with matching Eaton OEM load centers and panelboards, ensuring a tight fit, coordinated protection, and consistent electrical characteristics.
• Industry-ready versatility: Suitable for residential, commercial, and light industrial use where dependable branch circuit protection is essential.

Why this matters for your electrical system

In panelboards and load centers, protecting each branch circuit from overcurrent and short circuits is critical to prevent damage, reduce downtime, and maintain safety. The BRH320’s 20 A rating is precisely matched for common lighting and receptacle circuits, while its 240 V, 3-pole configuration supports efficient protection across multi-wire branch circuits and three-phase installations often found in commercial spaces.

Use cases and practical scenarios

• Upgrading aging panelboards in small offices or retail spaces where a reliable, easily replaceable breaker is needed.
• Installing in new commercial enclosures that require a plug-in molded-case breaker with clean, fast wiring and minimal panel disruption.
• Replacing a worn-out plug-in breaker in light industrial equipment circuits to restore consistent protection without a full panel overhaul.

What to expect in practice

The BRH320 delivers predictable trip behavior, reducing nuisance trips in environments with temperature fluctuations or varying load conditions. Its plug-in form factor simplifies serviceability, allowing technicians to swap breakers quickly and keep downtime to a minimum. When paired with compatible Eaton panelboards and load centers, you gain cohesive protection characteristics and streamlined maintenance across your electrical infrastructure.

For projects requiring dependable, manufacturer-aligned protection, the Eaton BRH320—20 A, 240 V, 3-pole plug-in molded case circuit breaker—offers a precise, durable solution that supports safe, continuous operation in both new installations and panel upgrades. Part Number: BRH320.
