Q2125 - 125Amp Circuit Breaker

Q2125 - 125Amp Circuit Breaker

Looking for a Q2125 circuit breaker to match an existing application? This 125-amp, 2-pole Type QP breaker has a plug-in design and is rated for 120/240 VAC, with a 10 kA I.C. rating. It’s also HACR-rated, making it suitable for qualifying heating, air-conditioning, and refrigeration applications where an HACR-rated breaker is called for. At 3.13 inches high, 2 inches wide, and 2.56 inches deep, the Q2125 keeps things relatively compact. More importantly, its clearly defined ratings make it easier to compare against the breaker you’re replacing or the requirements of your electrical equipment. Before installation, check the Q2125 part number and electrical ratings carefully; physical appearance alone isn’t enough to determine whether two breakers are interchangeable.
