FAQs
The CL115 is designed as a classified replacement for multiple brands, including Square D HOMELINE, GE THQ, Crouse-Hinds, Thomas & Betts, Murray, and ITE/Siemens load centers. This compatibility enables panel retrofits without full panel replacement, helping maintenance teams reduce downtime and inventory variety while preserving the protective characteristics of the original device.
The CL115 is a 15 A, 120/240 V, single-pole circuit breaker with a 10 kAIC interrupt rating. These specs matter because they define the maximum continuous current, operating voltage range, and fault-clearing capability, which together ensure safe operation for typical lighting and outlet circuits while providing robust protection against high-energy faults.
Yes. The CL115 is a classified 1-inch thermal magnetic breaker with a 15 A rating and 120/240 V operation, making it appropriate for both residential panels and light commercial applications where cross-brand compatibility and quick replacement are beneficial, especially in mixed-panel environments.
The CL115 carries UL 489 certification, which confirms conformity with established safety standards for low-voltage circuit protection. This certification helps ensure code compliance across many regulatory environments and provides confidence in long-term reliability and performance in protected circuits.
Using the CL115 can reduce downtime, simplify spare-part inventories, and minimize wiring errors by providing a common, cross-brand replacement solution. Its compatibility with multiple brands and load centers translates to faster commissioning, fewer field errors, and lower total cost of ownership over the lifecycle of mixed-brand installations.
