DZ267 Miniature Circuit Breaker
For protecting equipment against overload and short circuit.
2. General 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
Network normal voltage.
b.There are 1 curve characteristics for DZ267 magnetic operation:
C curve (5-10 In) protection and control of the circuits against
overloads and short-circuits; protection for resistive and inductive
loads with low inrush current.
