Eaton BQC230230 Miniature Circuit Breaker

The Eaton BQC230230 NSB miniature circuit breaker is a two-pole, 30-amp protective device built for 240-volt circuits and standard 50/60 Hz electrical systems. Identified by model BQC230230, it belongs to Eaton’s NSB family of MCBs and is designed to provide reliable overcurrent protection in residential and light commercial distribution panels where 2-pole protection is required. With a 240 V nominal rating and a 30 A current rating, it interrupts power on both conductors of a 2-pole circuit when an overload or short occurs, helping maintain electrical safety and system integrity. Commonly used for branch-circuit protection in residential panels and light commercial installations that require 240V two-pole protection.
