MCCB for line protection — 100 A frame with high interrupting capacity
The Siemens SENTRON 3VA2010-6HN32-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, with a rated insulation voltage of 800 V. It carries a 242 kA breaking capacity at 240 V AC, dropping to 187 kA at 415/440 V and 121 kA at 500 V — at 690 V the rating is 4 kA.
This order code carries a current lifecycle stage — no phase-out or last-time-buy has been announced. It remains a qualified part for serial-production BOMs without an imminent requalification trigger.
Thermal derating and power dissipation
Above that, derating applies: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. Maximum power loss is 13.5 W.
Panel integration — footprint and mounting
The 3-pole frame fits standard MCCB panel cutouts and bus-bar systems for the SENTRON 3VA platform. The shunt trip (STL) and auxiliary switch block (2 aux + 1 alarm) are factory-integrated — no field-assembly of those options required.
