It carries an interrupting capacity of 187 kA at 240 V AC, stepping down to 121 kA at 415/440 V, 79 kA at 500 V, and 4.25 kA at 690 V — enough headroom for most industrial main or feeder applications where high fault current is expected. Rated insulation voltage is 800 V, and it operates from -25 °C to 70 °C, with a thermal derating curve starting at 55 °C (96.25 A) down to 85 A at 70 °C. Maximum power loss is 12.5 W, which helps when sizing enclosure ventilation.
The 3VA1110-5EE32-0DC0 is a lower-interrupting variant (typically 65 kA at 240 V) in the same 3VA frame size. If your panel was specified around the 3VA1110, this unit will physically drop into the same mounting footprint and busbar connections, but the higher interrupting rating may require coordination re-check with downstream devices. No rewiring needed for the breaker itself.
