This breaker delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The 3-pole line-protection design means it's set up for feeder or main breaker duty, not motor protection — pair it with a separate overload relay if you're feeding a motor starter.
Auxiliary and communication features
The communication function lets this breaker talk to a higher-level control system — useful for energy monitoring or remote reset in a conveyor line where you want to know which zone tripped without walking the panel.
