It's a 3-pole unit with a continuous current rating of 100 A across ambient temperatures from 40 °C to 50 °C, derating to 91 A at 70 °C. The interrupting capacity is substantial: 121 kA at 240 V AC, 75.6 kA at 415 V, and it still holds 11.9 kA at 690 V.
Built-in auxiliary and release options
This variant ships with two factory-fitted auxiliary switches (HQ type) and an undervoltage release (UVR). The auxiliary switches give remote status feedback (open/closed/tripped) to a PLC or annunciator. No communication module or ground-fault monitoring on this code; it's a straightforward line-protection breaker with the basics covered.
The 3VA series shares the same mounting pattern across the 100 A frame, so if you're swapping from another 3VA variant, the bus-bar and lug positions are consistent.
Thermal derating curve
Above that, it derates linearly: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. If your panel interior runs hot — say near a transformer or in a non-ventilated enclosure — factor that derating into your conductor and load sizing.
Power loss and insulation rating
Maximum power loss is 27.5 W at rated current — that's heat the panel must dissipate.
