Its interrupting capacity hits 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V — so it handles high-fault utility feeds or transformer secondaries without cascading upstream. The TM240 release is fixed, not adjustable — what you see on the nameplate is what trips.
At 55 °C it derates to 15.36 A, at 60 °C to 15.04 A, at 65 °C to 14.72 A, and at 70 °C to 14.4 A. That 70 mm depth is shallow enough for most 200 mm deep enclosures; the 76.2 mm width (roughly 3 inches) is standard for a 3-pole MCCB footprint.
Mechanical endurance rated at 15,000 operations — typical for a 16 A MCCB in distribution duty. The storage limit covers shipping and warehouse, not running.
