What this 250 A MCCB does on your line
It carries a 3-pole configuration with an ETU560 electronic trip unit, designed for line protection duty — meaning it protects cables and busbars, not motor overloads. Interrupting capacity hits 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 7.5 kA at 690 V — that 330 kA figure tells you this breaker is built for high-fault utility feeds or transformer secondaries where available fault current is extreme.
A motor drive option is available as an optional extension, and the breaker supports communication functions — so you can integrate it into a BMS or SCADA system for remote trip indication and monitoring.
What the ETU560 trip unit gives you
It's field-adjustable via the front rotary dials and DIP switches, so you can coordinate selectively with downstream breakers without swapping trip units. At 250 A continuous, that's reasonable for an electronic-trip MCCB of this frame size. The 70 °C operating max matches the full-current rating — no derating curve to chase for high-ambient panels.
