It carries a 3-pole configuration and an adjustable trip class covering 10A, 10/10E, 20/20E, and 30/30E, letting you match the thermal curve to the motor start profile — a 10E class for quick-start pumps, a 30E for high-inertia loads like centrifuges. Breaking capacity is rated at 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V — the steep drop at 690 V means you need to verify the available fault current at that voltage before committing the BOM line.
Built-in communication function and phase failure detection mean this breaker can report status and trip events to a PLC or SCADA system, reducing fault-finding time on a down line.
