MCCB for high-fault panels
Its 100 A continuous rating (Iu) holds at ambient temperatures up to 50 °C without derating; at 55 °C it still carries 96.25 A, and at 70 °C it delivers 85 A — useful for panels with elevated internal heat. At 415/440 V it still breaks 121 kA, and at 690 V it drops to 3.4 kA — so for 690 V systems, verify the available fault current stays under that threshold. The overcurrent release is an ETU320 electronic trip unit, which provides adjustable long-time, short-time, and instantaneous protection curves. No auxiliary contacts, ground-fault monitoring, or communication function are built in; those would need separate add-on modules.
Panel builders should verify the depth clearance for the undervoltage release wiring and any rear-connection terminals.
