It carries a 187 kA interrupting capacity at 240 V, tapering to 121 kA at 415/440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V — so the SCCR headroom shrinks fast above 500 V; coordination studies need to account for the voltage-dependent curve, not just the top-line number.
Ratings and thermal performance
Continuous current holds at 250 A from 40 °C through 50 °C ambient, then derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. That 50 °C plateau is useful for non-climate-controlled enclosures; above that, the derating curve is linear enough to calculate intermediate points. Max power loss is 48 W — a non-trivial heat load in a sealed panel, so ventilation or a larger enclosure may be needed if the breaker runs near full load at elevated ambients.
Communication and auxiliary configuration
This order code includes a communication function — the basic switch variant is 3VA2225-5JP32-0AA0, so the -0AB0 suffix adds the comms module. No auxiliary release is fitted. The 2 HP auxiliary switches are wired internally; verify the contact arrangement against your control circuit before panel wiring.
