FAQ
-
What does "Type C" mean on this MCB?
Type C describes the tripping curve — it allows a higher inrush current (roughly 5–10 times the rated current) before tripping on short-circuit, which suits motors, transformers, and other inductive loads that draw a brief high current at switch-on without nuisance tripping.
-
What does the 6kA rating mean?
6kA is the breaking capacity — the maximum fault current this MCB can safely interrupt without damage. It should be equal to or higher than the prospective fault current at its installation point in the board.
-
How many poles do I need?
This is a 4-pole, 63A unit. Use 3 or 4 poles for a three-phase circuit, with 4-pole also switching neutral.
-
Can I install this myself?
No — MCBs are installed inside a distribution board on live busbars and must be fitted by a licensed electrician.
-
Will this fit my existing Hager distribution board?
Genuine Hager MCBs clip directly onto standard 35mm DIN rail and are designed to work across the Hager DB range — check your board's existing MCB range/series if you need an exact match.
