The interrupting rating drops as voltage rises: 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V.
Thermal derating curve
Above that, it derates linearly: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C.
That depth is tight for shallow enclosures — check gland-plate clearance before pulling cable. The breaker ships with 4 auxiliary switches (HQ design) and a basic switch (order code 3VA2225-5JP32-0AA0) for status feedback to the PLC.
Communication and power loss
This variant includes a communication function for remote trip indication, current monitoring, and parameterization. Maximum power loss is 48 W.
