This E-frame breaker is designed specifically for bolt-on installation in Square D NF series panelboards.
What does the SA suffix mean on the EDB34070SA catalog number?
The SA suffix indicates the breaker is equipped with a factory-installed 120VAC shunt trip. This accessory allows the breaker to be tripped remotely by an external control signal.
