SENTRON 3VM1050-4ED32-0AA0 — 500 A MCCB with TM210 Trip
Interrupting capacity runs 121 kA at 240 V AC, dropping to 76 kA at 415 V, 40 kA at 440 V, and 12 kA at 500 V — so at 400 V class panels this breaker clears faults up to 76 kA without upstream fusing. Continuous current holds at 50 A from 40 °C through 50 °C ambient, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C — the thermal curve matters if the breaker sits near other heat sources in a crowded enclosure. Physical footprint: 130 mm tall, 76.2 mm wide, 70 mm deep — fits standard 3-pole MCCB panel cutouts; the IP40 front face keeps dust out of the trip mechanism in a clean indoor panel.
Panel Fit & Integration
No undervoltage release, no shunt trip, no communication module — this is a straight thermal-magnetic breaker for line protection, not a smart or remotely-tripped device. Rated insulation voltage 800 V; operating range -25 °C to 70 °C, storage from -40 °C to 80 °C. Maximum power loss 15 W at rated load — negligible for most panel thermal budgets.
