Line protection MCCB with a wide thermal-magnetic range
Its TM240 thermal-magnetic release provides fixed overload and short-circuit protection without the need for external trip units. Breaking capacity is the headline spec here: 121 kA at 240 V AC, 75.6 kA at 415 V AC, 52.5 kA at 440 V AC, and 11.9 kA at 690 V AC. Thermal derating is published across the operating range: the breaker holds its full 16 A rating from 40 °C through 50 °C, then begins to step down — 15.36 A at 55 °C, 15.04 A at 60 °C, 14.72 A at 65 °C, and 14.4 A at 70 °C.
Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a standard SENTRON 3VA footprint that drops into existing panel layouts without re-drilling. The front face carries an IP40 protection rating, suitable for general-purpose indoor enclosures where tools or fingers are the main concern, not washdown.
