SENTRON 3VA1 MCCB — 63 A Line Protection
The 3VA1163-3ED42-0AA0: Breaking capacity reaches 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 11.9 kA at 690 V — figures that cover most commercial and light industrial fault levels.
Thermal Derating and Temperature Range
The 63 A rating holds steady from 40 °C through 50 °C, then derates linearly to 58 A at 70 °C. This means the breaker can be applied at full rating in most panel environments without a temperature-related upsizing, provided ambient stays below 50 °C. The IP40 front protection keeps tools and fingers out but does not seal against moisture — install in a dry enclosure.
At 130 mm tall, 101.6 mm wide, and 70 mm deep, this 4-pole MCCB fits standard SENTRON 3VA1 mounting footprints.
