Q245 - 45Amp Circuit Breaker

Q245 - 45Amp Circuit Breaker

Looking for a Q245 45 amp circuit breaker to match an existing application? This 2-pole Type QP plug-in breaker is rated for 120/240VAC and has a 10 kA AIC rating, providing the essential specifications you need to compare it with your panel or existing breaker quickly. It’s also HACR-rated, so it can be used in applicable heating, air-conditioning, and refrigeration applications where that rating is required. At only 2.88 inches high, 2 inches wide, and 2.56 inches deep, the Q245 has a compact plug-in design made for compatible equipment. If you’re replacing a breaker, don’t rely on amperage alone. Take a moment to compare the Q245 part number, 45A rating, two-pole configuration, Type QP design, voltage, and AIC rating with the requirements of your electrical panel. Getting those details right is the simplest way to determine whether this breaker is the right match for the job.
