SENTRON 3VA1110-6EE36-0AA0 — 100 A MCCB, TM220, 220 kA
The Siemens SENTRON 3VA1110-6EE36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated 100 A at 40 °C, with a TM220 thermal-magnetic release. Its interrupting capacity hits 220 kA at 240 V, dropping to 154 kA at 415 V and 121 kA at 440 V — still substantial for high-fault distribution panels. At 500 V and 690 V it holds 17 kA, so it handles standard 480Y/277 V services without issue.
The 100 A rating holds from 40 °C through 50 °C without derating — that's a full 10 °C margin over the standard 40 °C reference point. At 55 °C it's 98 A, at 60 °C it's 96 A, at 65 °C it's 94 A, and at 70 °C it's 91 A. For a panel running warm near the top of a switchboard, you lose less than 10 % capacity even at 70 °C ambient. At 415 V it's 154 kA, so it's still comfortable on high-fault 400 V distribution boards.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into SENTRON mounting bases or DIN-rail adapters. Maximum power loss is 25 W — that's the heat it dumps into the enclosure. In a densely packed panel, that matters for thermal management. No trip indicator, no undervoltage release coil to wire.
No obsolescence notice, no last-time-buy window. It's a standard SENTRON 3VA line-protection MCCB, widely specified for commercial and industrial distribution.
