Product Description
CKYB-63 MINI CIRCUIT BREAKER
GENERAL
1.1Applications:
For protecting cables and equipment against overload and short circuit
1.2General rules for choosing MCB.
A. 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. There are 2 curve characteristics for magnetic operation:
B. Curve (3-5In) protection and control of the circuits against overloads and short-circuits: Protection for people and big lengthcable in TN and IT systems.
C. Curve (5-10In) protection and control of the circuits against overloads and short-circuits: Protection for resistive and inductiveloads with low inrush current.
