Eaton BR320 - 20 A, 240 V, 3-Pole Plug-In Circuit Breaker | AmpState

The Eaton BR320 is a 20A, 240V, 3-pole plug-in molded case circuit breaker crafted to deliver dependable branch circuit protection in panelboards and loadcenters. Designed for rapid installation and easy replacements, this device helps minimize downtime during maintenance or panel upgrades while maintaining solid protection for your electrical system.

Why the BR320 stands out

• Fast plug-in connection for quick installation and simple swaps—no complex wiring rework, just secure, reliable connection to your Eaton-compatible panelboard.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining a slow-reacting thermal element with a fast-acting magnetic circuit breaker mechanism. This reduces nuisance trips on routine overloads and ensures immediate disconnection during short circuits.
• 3-pole, 240V design ideal for 240V panelboards and loadcenters, supporting multi-pole protection for 3-phase or multi-wire circuits common in commercial and light industrial settings.
• OEM compatibility engineered to pair with matching Eaton OEM loadcenters and panelboards, ensuring a precise fit, consistent trip characteristics, and straightforward field service.
• Versatile applications suitable for residential, commercial, and light industrial environments where reliable overcurrent and short-circuit protection is essential.

What problems does it solve?

In busy electrical spaces, downtime matters. The BR320 reduces installation time and service interruptions with its plug-in design, while the thermal-magnetic trip unit provides reliable protection against both sustained overloads and sudden faults. By aligning with Eaton’s OEM panelboards, it minimizes compatibility headaches and ensures predictable performance across your electrical infrastructure.

Ideal use cases

• New installations or panel upgrades in commercial facilities where 3-pole 240V protection is required
• Replacement of worn or degraded breakers in compatible Eaton panelboards and loadcenters
• HVAC equipment, lighting circuits, and light industrial machinery that run on 240V three-pole systems
• Residential or light commercial setups that demand rapid, reliable plug-in protection with easy maintenance
