QJ23B225H - 225Amp Circuit Breaker

QJ23B225H - 225Amp Circuit Breaker

When you're maintaining an existing electrical system, finding the right replacement breaker is just as important as matching the electrical ratings. The QJ23B225H molded case circuit breaker is a 225-amp, 3-pole breaker designed for applications that require 42kA interrupting capacity at 240VAC. Built with a Type QJ2H frame, it offers the form, fit, and functional compatibility needed for many commercial and industrial power distribution systems.

This breaker is calibrated for 40°C ambient conditions, making it well-suited for electrical rooms and other environments where temperatures may run warmer than standard conditions. It's also HACR rated, making it appropriate for heating, air conditioning, and refrigeration equipment where permitted by applicable electrical codes. To simplify installation, the breaker includes load-side lugs, reducing the need for additional components during replacement.

Whether you're performing scheduled maintenance, replacing a failed breaker, or keeping an existing system operating as intended, the QJ23B225H delivers the electrical ratings and compatibility needed for a dependable installation. Built to last, it's designed to provide consistent circuit protection while helping maintain the integrity of compatible electrical distribution equipment.
