Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V — meaning it can safely clear faults up to those levels without upstream coordination failure.
The 630 A rating holds at 40 °C ambient; above that, the breaker derates linearly to 520 A at 70 °C, with intermediate values at every 5 °C step. Maximum power loss is 164.5 W — a figure to account for in enclosure thermal calculations, especially when grouping multiple breakers in a compact panel.
Auxiliary configuration
The basic switch assembly is order code 3VA2463-5HL32-0AA0.
