630 A MCCB with line protection and communication
Breaking capacity spans 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V, so it handles high-fault industrial service entrances or distribution panels where available short-circuit current is substantial.
Bolts directly into a panel or enclosure bus; no DIN-rail clip on this frame size. The 3-pole design fits three-phase distribution, and the built-in communication function saves a slot that would otherwise need a separate module for remote monitoring.
Continuous current rating derates with ambient temperature: 630 A at 40 °C, 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. Maximum power loss is 164.5 W — relevant for enclosure thermal calculations, especially in sealed or high-ambient panels.
