Product FAQs
6 answersWhat panelboards are compatible with the ECB24020G3 circuit breaker?
This bolt-on circuit breaker is designed specifically for installation in Square D NF panelboards equipped with the Powerlink G3 Lighting Control System.
What does the G3 suffix indicate in the ECB24020G3 catalog number?
The G3 signifies that this breaker is a remotely operated component built for the Powerlink G3 lighting control system, incorporating an internal 24 Vdc motor for automated switching.
Does this Powerlink breaker allow for manual operation if the control system is offline?
Yes, this remotely operated breaker features a manual override selector on the front. Switching to manual mode disconnects the internal motor drive train, allowing the handle to operate the contacts like a standard circuit breaker.
Can this breaker be closed remotely if it has tripped?
No, the internal motorized mechanism can only open and close the contacts when the breaker handle is in the ON position. Contacts cannot be closed remotely if the breaker is tripped or if the handle is manually moved to the OFF position.
How does the interrupt rating change based on the system voltage?
The interrupting capacity is voltage dependent. It provides 65kA of protection at 120/240VAC, which decreases to 14kA when applied at its maximum rating of 480Y/277VAC.
What specific commercial load certifications does the ECB24020G3 carry?
This thermal magnetic breaker is listed for HACR (Heating, Air Conditioning, and Refrigeration) applications. It also carries SWD (Switch Duty) and HID (High-Intensity Discharge) ratings for commercial lighting systems.
