It carries a 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — so the available fault current at your service voltage is what determines whether this frame holds or you need to step up to a higher-rated SENTRON frame. This is a line-protection design, not a motor-protective breaker — it's sized for feeder and branch-circuit duty where you need selective coordination downstream.
Undervoltage release and communication
This is common in safety circuits where a loss of control voltage must open the main contacts. The UVR is wired separately; verify coil voltage compatibility with your control transformer before panel build. The breaker includes a communication function and an other measurement function for remote monitoring and energy metering via the SENTRON bus.
