MCCB for feeder and branch protection — 16 A, 3-pole, high interrupting capacity
Breaking capacity is rated at 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — figures that cover most industrial low-voltage fault levels up to 440 V with comfortable headroom. At 690 V the 10.5 kA rating is still adequate for many motor branch circuits, though coordination study is advised for high-fault installations. No undervoltage release, no auxiliary contacts, and no communication module are fitted on this variant.
Temperature derating and panel integration
Rated current holds at 16 A from 40 °C to 50 °C ambient, then derates linearly to 14.4 A at 70 °C. In a sealed enclosure or high-ambient panel, the 55 °C derating to 15.36 A and 60 °C to 15.04 A should be factored into the load schedule. No auxiliary contact slot is populated, so any status feedback requires an external monitoring relay or a separate auxiliary contact block (not included).
