What this 4-pole 100 A MCCB does on the line
Breaking capacity runs 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V — the 240 V figure is the highest in this frame class, sized for high-fault utility or transformer-fed service entrances where the available fault current is well above 100 kA.
Built-in communication and ground-fault monitoring
This MCCB includes a communication function and an other measurement function, plus summation-current ground-fault monitoring on the L + N conductor — meaning it can report status and trip events to a higher-level control system and detect leakage currents without a separate external relay. The undervoltage release is not fitted as standard; if you need UVR for your safety circuit, that's an accessory add-on.
Current production — no lifecycle concern
Power loss is 13.5 W maximum at rated load — a modest figure for a 100 A frame that keeps internal temperature rise manageable inside a crowded enclosure.
