MCCB for line protection with undervoltage release
Interrupting capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V, covering most industrial fault-current scenarios. Current rating holds at 160 A from 40 °C through 50 °C, then derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Maximum power loss is 40.5 W.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that drops into most DIN-rail or panel-mount assemblies without re-drilling.
