Eaton BR370ST - 70 A, 240 V, 3-Pole Plug-In Circuit Breaker | AmpState

The Eaton BR370ST is a rugged 70A, 240V, 3-pole plug-in molded case circuit breaker designed to deliver reliable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built for fast, clean installs, this unit snaps into compatible OEM panels for minimal downtime and max uptime.

Key benefits for real-world electrical protection

• Fast plug-in connection enables quick installation and straightforward replacement, reducing panel downtime during maintenance or upgrades.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining temperature-sensitive delay with a magnetic short-circuit trip, helping minimize nuisance trips while delivering decisive disconnection under high fault current.
• 3-pole, 240V design suited for 3-phase distribution or multi-wire systems, ensuring coordinated protection across all live conductors.
• OEM panelboard compatibility engineered to integrate with matching Eaton OEM load centers and panelboards, supporting seamless upgrades or replacements without custom adapters.
• Rugged molded case construction protects sensitive electronics from common on-site stresses, making it a dependable choice for residential, commercial, and light industrial applications.

Where this breaker shines

• and light commercial electrical closets upgrading or expanding panel capacity, particularly where a 70A, 3-pole, 240V protection device is needed.
• such as HVAC units, pumps, and lighting circuits where rapid fault isolation and predictable protection curve reduce downtime.
• Panelboard refurbishment—swap-in replacements that align with OEM specifications to maintain panel labeling, coordination, and warranty expectations.

Why the BR370ST matters for your electrical safety and reliability

• Proven protection performance through a balanced thermal-magnetic mechanism that responds accurately to overloads while delivering quick disconnection for short circuits.
• Plug-in ease minimizes service disruption, making routine maintenance and part replacement faster and more predictable than bolt-on or retrofit solutions.
• Designed with panel compatibility in mind, helping you preserve coordination with other protective devices and simplifying documentation for code compliance.
