FAQs
The CL230CS is designed as a Type CL 1-Inch classified replacement for Type CH load centers. It also lists cross-reference compatibility with common brands such as Square D Homeline and GE THQ, enabling easier field upgrades. It requires two 1-inch spaces in the panel and accepts #14-4 AWG Cu/Al conductors, making it suitable for shared-mount installations and multi-branch circuits in typical commercial and light-industrial panels.
The CL230CS is a two-pole breaker rated at 30 A with a voltage rating of 120/240 V and an interrupt rating of 10 kAIC. It is UL 489 listed and intended for CH load centers. The unit features a common-trip mechanism to ensure simultaneous disconnection of both poles, enhancing protection for multi-wire branch circuits.
Yes. The CL230CS provides a common breaker trip for both poles, ensuring simultaneous disconnection across multi-wire branch circuits. This is critical for maintaining safety and reducing the risk of shared-neutral faults in CH load centers used in industrial and commercial environments.
The CL230CS occupies two spaces in a panel and measures 7.25 inches in length, 6.5 inches in height, and 4.48 inches in width, with a weight of about 2.18 pounds. It is designed to fit CH load centers and aligns with the two-space requirement noted in catalog documentation.
Choosing the CL230CS offers cross-brand compatibility, UL 489 safety certification, and a clamshell packaged unit that simplifies handling and stocking. Its 30 A, 120/240 V two-pole configuration supports common commercial and light-industrial loads, reducing downtime during upgrades and ensuring reliable protection across CH load centers, which translates to lower maintenance costs and improved uptime.
