Ratings and fit
The 3VA1163-3ED12-0AA0: Rated 63 A from 40 °C through 50 °C, then derates to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C — the full thermal curve is published, so a panel designer can size for elevated ambient without guesswork. The interrupting rating is 52.5 kA at 240 V AC and 7.5 kA at 415 V AC; the insulation voltage is rated 500 V, and the operating voltage at AC is 415 V. The TM210 release means the thermal element is fixed, not adjustable — set the continuous load below 63 A and let the magnetic pickup handle short-circuit events.
Integration and panel fit
Width is 25.4 mm (1 inch) — a single-pole MCCB that fits a standard 25 mm module slot on a DIN rail or panel-mount assembly. Depth is 70 mm, height 130 mm. Front protection is IP40, suitable for enclosed distribution boards where no water ingress is expected. Max power loss is 5.77 W, which factors into thermal budgeting inside a sealed enclosure. No trip indicator, no undervoltage release, no ground-fault monitoring — this is a bare thermal-magnetic breaker for straightforward line protection.
