Its adjustable thermal-magnetic trip unit covers a range from 240 A minimum to 1 600 A maximum, giving you flexibility to tune the overload and short-circuit protection to the actual load rather than swapping breakers.
This MCCB delivers 330 kA at 240 VAC, dropping to 242 kA at 415 V and 440 V, then 187 kA at 500 V, and 3.7 kA at 690 V.
Thermal performance across temperature
That's unusual for an MCCB; most start dropping above 40 °C.
Ground-fault monitoring and ratings
It includes ground-fault monitoring via summation current formation on the L + N conductors — useful for detecting leakage without a separate GFCI module.
