This 3-pole unit delivers 242 kA interrupting capacity at 240 V and 187 kA at 415 V, with a minimum of 5 kA at 690 V — covering most industrial distribution panels and motor control center infeeds.
The 100 A rating holds flat from 40 °C through 50 °C, then derates linearly to 85 A at 70 °C (–). For a panel that runs warm — say a packed MCC bucket at 55 °C — the usable current drops to 96.25 A, so the breaker should be upsized if the load is continuous at the full 100 A. This makes the breaker suitable for selective coordination studies — you can set the short-time delay to ride through downstream faults without nuisance tripping the main.
Physical fit and integration
Comparison note against a sibling
The closest functional sibling is the 3VA2110-7HK42-0AA0, which shares the same 100 A frame and 3-pole count but carries a different trip unit configuration. The 3VA2110-6HN36-0AH0 includes the HQ auxiliary contact block (2 aux + 1 trip alarm) as standard.
