MCCB for line protection — 160 A, TM240 release
Breaking capacity is 220 kA at 240 V AC, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. The thermal-magnetic release is fixed (TM240), meaning the thermal pickup and magnetic trip thresholds are factory-set, not field-adjustable. Operating temperature range is -25 °C to 70 °C; current derating begins above 50 °C: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, 144 A at 70 °C.
The 70 mm depth leaves clearance for rear-connected busbars or cable lugs in a typical 200 mm deep enclosure. Latching endurance is rated at 15,000 operations.
