MCCB for 250 A Line Protection
The 250 A rating holds flat through 50 °C, then derates to 238 A at 55 °C and 200 A at 70 °C — useful when the breaker sits near other heat sources in a crowded enclosure.
Interrupting Performance and Panel Fit
Fault current capability drops with voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4.5 kA at 690 V. The 86 mm depth, 105 mm width, and 181 mm height (3.39 x 4.13 x 7.13 in) mean it fits standard MCCB panel cutouts. A built-in trip indicator speeds fault diagnosis on the line. Communication function is present, enabling integration with monitoring systems.
