Rated current and thermal performance
The 3VA2440-7HL32-0JC0 carries a 400 A continuous rating that holds flat from 40 °C up to 70 °C — no derating curve to calculate across that band. Frame size is 4800 A; adjustable trip range 600 A to 4800 A.
Interrupting capacity by system voltage
SCCR is 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and drops to 9 kA at 690 V. At 690 V the breaker is effectively a load-break switch for fault-clearing; coordinate upstream if your system runs at that level.
Physical fit and accessories
Footprint is 138 mm wide × 248 mm high × 110 mm deep. Ships with a shunt trip (STL) auxiliary release and two HQ auxiliary switches installed. No undervoltage release, no ground-fault module, no communication function on this variant.
