Product FAQs
7 answersWhat panelboards are compatible with the ECB142020G3EL circuit breaker?
This bolt-on breaker is specifically designed for installation in Square D NF lighting panelboards that utilize the Powerlink G3 lighting control system.
What does the "EL" suffix indicate on this Powerlink G3 breaker?
The "EL" designates it as an Emergency Lighting circuit breaker. It features a remotely operated switched circuit for standard lighting control and a manually operated unswitched circuit that provides continuous power to emergency equipment charging systems, complying with NEC 700.12(E).
How is the remote switching mechanism powered?
The remote operation is driven by an integrated 24Vdc motor connected to the Powerlink G3 control bus. This allows the system to open and close the contacts as long as the breaker handle remains in the ON position.
Can the breaker be operated manually if the automated lighting control system goes offline?
Yes. The breaker includes a manual override selector on the front. Engaging manual mode disconnects the motor drive train, allowing you to operate the contacts using the handle just like a standard thermal-magnetic circuit breaker.
Will the remote control system allow the breaker to close if it has tripped?
No. For safety, the contacts cannot be closed remotely if the breaker has tripped due to an overload or short circuit, or if the handle has been manually moved to the OFF position.
Does this breaker provide standard overcurrent protection in addition to remote switching?
Yes. It features a permanent thermal-magnetic trip unit with true RMS sensing, providing the same reliable overload and short-circuit protection as a conventional Square D circuit breaker.
How can I visually verify if the ECB142020G3EL has tripped?
The breaker features a VISI-TRIP indicator. When the breaker trips due to an overcurrent or short-circuit fault, the handle moves to a center position and a highly visible red indicator appears.
