The 242 kA breaking capacity at 240 V (187 kA at 415 V, 85 kA at 440 V, 55 kA at 500 V, 9 kA at 690 V) covers high-fault installations where the available short-circuit current is substantial — common in industrial distribution switchboards and large panelboard mains. ## Thermal derating and continuous current Above that, derating is linear: 388 A at 55 °C, 380 A at 60 °C, 368 A at 65 °C, 352 A at 70 °C. At 70 °C the part still delivers 352 A, which is 88% of the nameplate rating. ## Trip unit and protection functions Communication function is present, which allows integration into a power monitoring or SCADA system — useful for a facility engineer tracking trip events or doing remote coordination studies. The breaker also carries an 'Other Measurement Function' flag, indicating it can report electrical parameters beyond basic protection. Dimensions are 248 mm height, 138 mm width, 110 mm depth. The 110 mm depth leaves clearance for rear-mounted bus bars or cable lugs in a typical 600 mm deep enclosure.","metaTitle":"Siemens 3VA2440-6KQ32-0AA0 SENTRON MCCB, 400 A, 242 kA","metaDescription":"Siemens SENTRON 3VA2440-6KQ32-0AA0 molded case circuit breaker, 3-pole, 400 A continuous, 242 kA at 240 V.
