Its continuous current rating holds at 250 A across the full ambient temperature range from 40 °C to 70 °C, so no derating curve is needed for warm enclosures up to that ceiling. At 240 V it interrupts 242 kA; at 415 V and 440 V it holds at 187 kA; at 500 V it drops to 121 kA; and at 690 V it is still rated for 7.5 kA.
Panel fit and auxiliary configuration
The breaker measures 248 mm high × 138 mm wide × 110 mm deep — a standard 3-pole MCCB footprint that fits most distribution panelboards and switchgear cubicles without requiring a sub-panel adapter. The supplied basic switch is order code 3VA2325-6HL32-0AA0, which is the thermal-magnetic trip unit base; this variant adds 2 auxiliary switches plus 1 trip alarm switch (HQ type), giving the control system both position feedback and a dedicated fault signal without an external relay. If the application requires remote tripping or earth-leakage detection, a different 3VA variant or an add-on module would be needed.
Environmental limits and power loss
Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
