Ratings that matter for fit
At 55 °C it drops to 96.25 A, and at 70 °C it's 85 A. Breaking capacity drops as voltage climbs: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 3.4 kA at 690 V. On a 480 V system (common in North America) you're between the 440 V and 500 V curves — plan for the 79 kA figure at 500 V as the conservative bound.
Auxiliaries and releases
Comes with an integrated undervoltage release (UVR) — if control power drops, the breaker trips. That's a safety feature for emergency-stop chains or undervoltage protection on motor circuits. The trip alarm signals a fault event; the electrical alarm can be wired to a PLC for remote status. The basic switch is order code 3VA2010-5HL32-0AA0, and the integrated auxiliary trip is 3VA9608-0BB11 — useful if you need to order spare contact blocks separately.
