Product FAQs
6 answersWhat panelboards are compatible with the ECB34020G3 circuit breaker?
This breaker is designed exclusively for Square D NF panelboards equipped with a Powerlink G3 control bus. It requires the control bus strip to plug into for remote operation.
What makes the Powerlink G3 ECB34020G3 different from a standard branch breaker?
The ECB34020G3 is a controllable circuit breaker featuring an internal motor. This allows facility operators to remotely switch lighting and other loads without needing external contactors or relays.
Is the ECB34020G3 rated for switching specialized commercial lighting?
Yes, this breaker is fully HID (High-Intensity Discharge) and SWD (Switching Duty) rated for commercial lighting management. It is also HACR rated for heating, air conditioning, and refrigeration equipment.
Does this breaker require additional control wiring for remote operation?
No additional external control wiring is needed at the breaker itself. The internal motor operator receives its control signals by plugging directly into the Powerlink G3 control bus strip installed in the NF panelboard.
Can I substitute a standard EDB34020 breaker for the ECB34020G3?
While both are 3-pole, 20A bolt-on breakers for NF panels, the standard EDB34020 lacks the internal motor operator. If your system relies on Powerlink G3 automated switching, you must use the ECB34020G3 to maintain remote control functionality.
Does this breaker provide visual trip indication?
Yes, it features the Square D Visi-Trip indicator. This provides clear visual confirmation when the breaker has tripped, allowing for rapid fault identification in the panelboard.
