Square D BR230 2-pole 30A Plug-on Circuit Breaker

Product Description

The SQUARE D BR230 is a 2-pole, 30-amp plug-on circuit breaker designed for use in BR Series load centers. Rated for 120/240 volts AC with a 10 kiloamp interrupting rating, it provides common-trip operation across both poles — meaning a fault on either leg simultaneously opens the circuit. Accepts copper or aluminum conductors from 14 to 4 AWG. Electricians install this breaker as a branch-circuit or feeder protective device in residential and light commercial panelboards. Its plug-on mounting design allows fast, tool-free seating into compatible load centers.

The BR230 is suited for 240-volt branch circuits in residential and light commercial applications, including double-pole loads such as dryers, water heaters, HVAC equipment, and sub-panel feeds. It seats directly into BR Series load centers without additional hardware. The common-trip mechanism ensures both poles open together, meeting NEC requirements for multi-wire branch circuit protection on 2-pole loads.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the load center and verify the main breaker is off before handling any breaker or wiring. Confirm conductor size and material match the breaker rating before terminating wires. Do not exceed the panel's maximum breaker count or total ampacity as labeled on the load center.
