QJ23B070H - 70Amp Circuit Breaker

QJ23B070H - 70Amp Circuit Breaker

When you need a compatible replacement breaker to keep an existing electrical system operating as intended, the QJ23B070H is built for the job. This 70-amp, 3-pole molded case circuit breaker is designed for use in compatible Type QJ2H electrical distribution equipment, providing dependable protection against overloads and short circuits within its rated capacity. With a 42kA interrupting rating at 240VAC, this breaker is well-suited for many commercial and industrial applications where a higher available fault current is present. Its 40°C ambient rating allows it to perform in demanding electrical environments, while the HACR rating makes it appropriate for compatible heating, air conditioning, and refrigeration equipment. Because it includes load-side lugs, installation is more convenient by reducing the need for additional accessories. Whether you're maintaining a manufacturing facility, office building, retail location, or another commercial property, finding the correct replacement matters. The QJ23B070H is built to last and is intended to provide the proper form, fit, and function for compatible legacy electrical systems, helping you keep existing equipment in service without changing the original system design.
