SENTRON 3VA1010-3ED36-0AF0 — 100 A MCCB, Line Protection, Active Production
Its TM210 overcurrent release provides thermal-magnetic protection, adjustable to a maximum time delay tr of 1 s, making it suitable for feeder circuits in distribution panels where coordination with downstream devices is required. The breaker carries a rated insulation voltage (Ui) of 800 V, with breaking capacities of 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V — covering most low-voltage distribution fault levels.
Thermal Derating and Panel Fit
Rated current holds at 100 A from 40 °C through 50 °C ambient; above that it derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C — a gentle slope that keeps the breaker usable in warm enclosures without oversizing. Dimensions of 130 mm height, 76.2 mm width, and 70 mm depth fit standard panel cutouts for 3-pole MCCBs; the IP40 front protection suits indoor distribution boards. The auxiliary contact configuration — 1 auxiliary switch plus 1 trip alarm switch (HQ version) — provides status feedback for remote monitoring or PLC inputs without requiring an external relay.
