Rated 160 A continuous at 40 °C, it holds that full rating through 50 °C (–), then derates gently to 150 A at 70 °C. That thermal curve is what matters for a panel builder: you can size the breaker for a 160 A bus without oversizing the enclosure for derating, as long as ambient stays under 50 °C. Above that, you lose roughly 1 A per 5 °C rise. At 240 V it handles 187 kA; at 415 V, 121 kA; at 440 V, 75.6 kA; at 500 V and 690 V, 17 kA (–). For a 480 V panel in North America, the relevant figure is the 415 V rating — 121 kA — which covers most utility transformer secondary faults. The trip indicator gives a local visual flag — useful when the breaker is in a remote MCC bucket and you need to confirm it tripped before resetting.
Panel fit — DIN-rail footprint and wiring constraints
The 3VA1116-5EE32-0HH0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall. That 76.2 mm width — exactly 3 inches — is the standard 3-pole MCCB footprint for the SENTRON 3VA platform.
