It carries a 242 kA breaking capacity at 240 V, dropping to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 5 kA at 690 V — the interrupting capability scales with system voltage, so match the rating to your fault-current study at the point of installation.
The 63 A rating holds flat through 50 °C ambient; above that it derates in steps — 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C. If your panel runs hot, size the load side accordingly. Maximum power loss is 6.5 W, manageable in a ventilated enclosure.
Trip unit and auxiliary configuration
A mechanical trip indicator is present for visual fault status.
