Line protection MCCB with TM240 release
Its TM240 thermal-magnetic release gives a fixed 16 A continuous rating that holds flat across 40 °C to 50 °C, then derates to 14.4 A at 70 °C; that thermal curve matters when the breaker sits in a warm enclosure alongside other heat sources.
Breaking capacity — what the voltages mean for panel coordination
This MCCB delivers 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V.
Built-in auxiliaries and shunt trip
The integrated auxiliary trip module carries order code 3VA9688-0BL32, which is the specific subassembly if a replacement is ever needed.
Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep — standard 3VA frame size that mounts on a DIN rail or via screw terminals in a distribution board.
