Meba main circuit breaker MBI32-100
protection of circuits against short-circuit currents,
protection of circuits against overload currents,
MB132-100 circuit-breakers are used in domestic installation,
as well as in commercial and industry electrical
high protective grade(up to IP20), high breaking capacity,
reliable sensitive action, convenient, long life etc.
Technical data of the network at the point considered:
the earthing systems (TNS, TNC),
short-circuit current at the circuit-breaker installation point,
which must always be less than the breaking capacity of this device,
Network normal voltage.
B curve (3-5In) protection for people and big length cables in TN and IT systems.
C curve (5-10In) protection for resistive and inductive loads with low inrush current.
D curve(10-14In) protection for circuits which supply loads with high inrush current
at the circuit closing (LV/LV transformers, breakdown lamps).
