This MCCB delivers 187 kA at 240 V AC, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
Thermal performance and ambient derating
Maximum power loss is 4 W, negligible for enclosure heat calculations.
Ground-fault monitoring and protection design
The unit includes summation current ground-fault monitoring on the line conductors—it measures vector sum of the phase currents to detect leakage to earth. The adjustable thermal-magnetic trip range is 95 A minimum to 756 A maximum, with a fixed 16 A initial setting.
Panel integration
No DIN-rail mount; direct screw-mount to the backplate or busbar system.
