That thermal stability means this breaker fits enclosures with limited airflow without forcing a downsized selection at typical panel ambient temperatures. Breaking capacity spans the voltage range: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The TM240 thermal-magnetic release provides fixed instantaneous and overload protection — no electronic adjustment, which simplifies specification for standard distribution panels where the fault current profile is well understood. Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a compact footprint for a 3-pole MCCB in this current class.","metaTitle":"Siemens 3VA1180-3EF36-0AF0 SENTRON MCCB, 80A, 3-Pole, TM240","metaDescription":"Siemens 3VA1180-3EF36-0AF0 SENTRON molded case circuit breaker, 80A rated at 40°C, 3-pole, TM240 release, 75.6kA at 240V.
