The adjustable thermal overload range starts at 8 A and goes to the 40 A full-scale value, giving you a wide window to match the motor FLA without swapping breaker frames.
Interrupting capacity — what those kA numbers mean for your panel
This breaker delivers 330 kA interrupting capacity at 240 V, dropping to 242 kA at 415 V and 440 V, then 187 kA at 500 V, and 3.7 kA at 690 V. For most 400 V class motor control centers, the 242 kA figure gives enormous headroom over typical 50-65 kA SCCR panels.
Protection and communication features
It also carries a communication function and an 'other measurement function' capability, which suggests it can report trip data and status over a bus, though the exact protocol isn't specified here. No undervoltage release is fitted, so if you need UVR for your safety circuit, that's an accessory add-on.
No trip indicator window on the front — you'll need to read the handle position or use the communication output for status.
