Line protection MCCB with TM240 release
Above 50 °C the rating steps down in 0.8 A increments per 5 °C, reaching 36 A at 70 °C — useful to know when the breaker sits in a densely packed panel where internal heat rise is a factor. Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — the 415 V figure is the one most often checked for 400 V-class distribution panels in IEC markets. The auxiliary trip module is order code 3VA9608-0BB11. No voltage trigger, no communication function, no ground fault monitoring — it is a straight thermal-magnetic breaker with UVR and aux contacts.
Panel fit and operating conditions
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration. These numbers matter when the breaker is in a non-climate-controlled cabinet near a furnace line or outdoor substation.
