QHB230 - 30Amp Circuit Breaker

QHB230 - 30Amp Circuit Breaker

The QHB230 is a 2-pole, 30-amp bolt-on circuit breaker designed to provide dependable overcurrent and short-circuit protection in commercial and industrial electrical distribution systems. Featuring a 65kA interrupting capacity at 120/240VAC, this breaker is well suited for installations where higher available fault current demands a breaker with greater interrupting performance. Its bolt-on mounting design helps create a secure, vibration-resistant connection to compatible panelboards, making it an excellent choice for demanding applications where reliability and long-term performance are essential. Whether you're replacing an existing breaker during maintenance or supporting a panel upgrade, the QHB230 delivers the electrical protection and consistent operation professionals expect while helping keep electrical systems running safely and efficiently.
