The 3-pole construction with FF (fixed front) terminals suits it for panel mounting in motor branch circuits, where the MCP function provides short-circuit and overload protection coordinated with downstream contactors and overload relays. The UL listing confirms acceptance in North American switchgear assemblies; the ABB designation covers IEC markets as well.
What the 600 A MCP rating means for fit
The 600 A MCP rating is the short-circuit and overload protection setting for a motor branch circuit. It is not a continuous-current rating for a resistive load — the XT6H frame itself is rated 800 A, but the MCP trip unit is set at 600 A to coordinate with a motor of that locked-rotor current. In practice, this breaker protects the feeder and starter from fault currents while letting the motor's overload relay handle running overcurrent. The EKIP M DIP I allows field adjustment of the magnetic pickup and the thermal memory, so the same frame can be tuned to different motor sizes within the 600 A window.
