63 A MCCB with undervoltage release — line protection for distribution panels
Its breaking capacity reaches 52.5 kA at 240 V, 32 kA at 415 V, and 7.5 kA at 690 V — figures that govern its ability to safely interrupt fault currents at the installed voltage level.
The 52.5 kA at 240 V is the highest short-circuit current this MCCB can interrupt at that voltage; at 415 V the capacity drops to 32 kA, and at 690 V to 7.5 kA.
Rated current holds at 63 A from 40 °C through 50 °C, then derates to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. The TM210 overcurrent release handles the thermal-magnetic trip curve. Maximum power loss is 19.8 W.
