Eaton 30/40 amps Plug-In 4-Pole Circuit Breaker is a purpose-built safety device designed for BR-series panels, delivering reliable protection for 120/240-volt circuits. This four-pole, plug-in breaker brings the power and precision you need for demanding electrical setups while simplifying maintenance and upgrades in residential, commercial, or light-industrial settings.
Why choose a 4-pole design? A four-pole configuration lets you disconnect all poles simultaneously, which is essential for multi-wire branch circuits (MWBC) with shared neutrals or any equipment that requires coordinated shutdown across multiple hot legs. In practical terms, you get enhanced safety, easier servicing, and compliant disconnection for complex loads without juggling multiple devices.

How this breaker adds value in real-world setups
If you’re wiring a multi-wire branch circuit or feeding multiple loads from a single panel, this 4-pole plug-in breaker simplifies your electrical design. Its coordinated trip mechanism ensures all poles disengage together during a fault, reducing the risk of shared-neutral overloads and improving overall panel safety. The plug-in format means you can swap or upgrade breakers quickly during renovations or load changes, with less downtime and fewer tools required.
Ideal for:
- Residential and light commercial panels that use Eaton BR breakers
- MWBC installations requiring simultaneous disconnection of multiple hot legs
- Applications where a robust 30/40 A protection strategy is needed for 120/240 V circuits
