Line protection MCCB with TM210 release
The 80 A rating holds flat from 40 °C through 50 °C, then derates to 72 A at 70 °C, which is the upper operating limit. Breaking capacity varies with line voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V.
Dimensions are 70 mm deep, 101.6 mm wide, 130 mm tall — a standard 4-pole MCCB footprint that fits Siemens SENTRON distribution blocks and DIN-rail mounting. This variant ships without auxiliary contacts or a phase-failure detection module. The only integrated auxiliary release is a shunt trip (STL), order code 3VA9688-0BL33, which must be specified separately if remote tripping is needed.
