Common questions on this part
On the front face below the toggle handle, a rotary dial allows continuous adjustment of the thermal overload trip threshold from 0.8 to 1.0 times the nominal current (e.g. 200A to 250A).
Yes. Each BLX-MCCB-6000 is supplied with snap-in high-dielectric interphase barrier plates that prevent accidental arcing or flashover between adjacent line and load terminals.
Yes. Internal accessory pockets accommodate snap-in auxiliary contacts (OF), alarm contacts (SD), and shunt trip coils (MX) for remote emergency tripping or automation feedback.
Yes. The breaker complies fully with IEC 60947-2 standards recognized by Kenya Bureau of Standards (KEBS) and Kenya Power.
Yes. STARNEX stocks 100A, 125A, 160A, 200A, 250A, and 400A MCCBs at our Enterprise Road trade counter for immediate collection.
