Its interrupting capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — figures that cover most industrial distribution panels and motor control center feeder circuits. There is no auxiliary contact block, no communication module, and no phase-failure detection; the part is a straightforward thermal-magnetic MCCB for basic overcurrent and short-circuit protection. The TM240 release is a fixed thermal-magnetic design — no interchangeable trip units, no electronic adjustments. For a panel builder, that means the breaker is set at the factory for 80 A and cannot be field-recalibrated. The 15,000 latching endurance cycles indicate the mechanical life under load-switching conditions; this is a distribution breaker, not a switching device for frequent motor starts. Above that, the TM240 release begins to thermally derate: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C.","metaTitle":"Siemens 3VA1180-4EF36-0CA0 SENTRON MCCB, 80 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1180-4EF36-0CA0 molded case circuit breaker, 80 A, 3-pole, 121 kA at 240 V.
