UB MCB

UB Miniature Circuit Breaker
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.
Tripping curves:
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.
