Product FAQs
6 answersWhat panelboards are compatible with the ECB14015G3 circuit breaker?
This breaker is designed for installation in Square D NF lighting panelboards equipped with the Powerlink G3 Lighting Control System. The panelboard must have a control bus strip to interface with the breaker.
How does the remote operation function on the ECB14015G3?
The breaker features a built-in 24 Vdc motor and drive train that can remotely open and close the contacts when the handle is in the ON position. The contacts cannot be closed remotely if the handle is in the OFF position or if the breaker has tripped.
Can the ECB14015G3 be operated manually if the automated control system is offline?
Yes. A manual override selector on the front of the breaker bypasses the automated control command. In manual mode, the motor drive train disconnects, allowing you to operate the handle manually like a conventional circuit breaker.
Is the ECB14015G3 suitable for switching high-intensity discharge lighting?
Yes, this breaker is UL listed and HID rated, making it suitable for switching high-intensity discharge lighting systems commonly used in commercial facilities.
Can this Powerlink G3 breaker be used with HVAC equipment?
Yes, the ECB14015G3 is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment motor group combinations.
Does the remote switching capability affect the overcurrent protection of the breaker?
No. The ECB14015G3 provides the same thermal-magnetic overload and short-circuit protection as a standard circuit breaker, utilizing a true RMS sensing thermal trip element calibrated for 40 degrees Celsius ambient temperature.
