Powerlink™ ECB-G3 Circuit Breakers

Remotely Operated Circuit Breakers

Powerlink G3 remotely operated circuit breakers are designed for installation in Schneider Electric NF lighting panelboards as part of the Powerlink G4 Lighting Control System. These circuit breakers provide the same overcurrent protection as found in standard circuit breakers.

• Robust 24 Vdc motor and trip mechanism provide remote operation capability in terms of compact size, electrical ratings, and mechanical life.

• Motor and drive train can open and close the contacts when the circuit breaker handle is in the ON position.

• Contacts cannot be closed remotely when the handle is in the OFF position, or the circuit breaker is tripped.

• Manual override selector located on the front of the circuit breaker provides bypass of automated control command.

• In manual mode, the motor drive train is disconnected from the contact, allowing the circuit breaker handle to operate the contacts like a conventional circuit breaker.

• Remote contact status indication determines the presence or absence of voltage on the load side terminal of the circuit breaker.

Tripping System with RMS Sensing

• Schneider Electric Powerlink ECB-G3 circuit breakers have a permanent trip unit that contains a factory preset thermal (overload) trip element and a magnetic (short circuit) trip element in each pole.

• The thermal trip element—true RMS sensing—is calibrated to carry the continuous current rating of the circuit breaker at 140°F (40°C) free air ambient temperature.
