Product FAQs
6 answersWhich load centers are compatible with the Eaton CL240 circuit breaker?
The CL240 is a UL Classified 1-inch replacement breaker. It is rigorously tested and approved for use in load centers manufactured by Square D (Homeline series), GE (Type THQ), Siemens/ITE (Type QP), Murray (Type MP), Crouse-Hinds (Type MP), and Thomas & Betts (Type TB).
How much panel space does the CL240 require for installation?
This 2-pole breaker requires two standard 1-inch spaces, taking up a total of 2 inches on the panel bus.
Does the CL240 feature a common trip mechanism?
Yes, this 2-pole breaker utilizes an internal common trip. If an overload or short circuit occurs on either leg, both poles will trip simultaneously to completely disconnect the 240V load.
Can I use the CL240 to replace a Square D Homeline or Siemens QP breaker?
Yes. Eaton CL series breakers are UL 489 listed and specifically classified to safely replace 1-inch format breakers from other major brands, including Square D Homeline, Siemens QP, and GE THQ, without voiding the panel's UL listing.
What type of protection does the CL240 provide?
It provides standard thermal-magnetic protection, utilizing a bimetallic element for long-time overload protection and an electromagnetic assembly for instantaneous short-circuit protection.
Is the Eaton CL240 UL listed for use in competitor panels?
Yes, it carries a UL classification specifically for use in select competitor load centers. This classification ensures that installing the CL240 will not violate National Electrical Code (NEC) Article 240.7 requirements or void the original panel listing.
