What are the main current parameters of dc circuit breakers in low voltage circuit breakers?

Key technical parameters are as follows:

1) Inm - low voltage circuit breaker shell bracket rated current (A)

2) In -- low voltage circuit breaker rated current (A)

3) Icu - rated limit short circuit breaking current (A)

4) Ics - rated running short circuit breaking current (A)

5) Icw - rated short term tolerable current (A)

6) Ib -- line load calculation current (A)

7) Id - voltage circuit breaker load side short circuit current (A)

The relationship is as follows: Id < Icu > Ics > Icw

Inm s > In > Ib

Small dc circuit breaker for dc voltage to the DC1000V, rated current 63 a circuit overload and short circuit protection, can also be used for solar photovoltaic power generation systems, TX7-63 - z series of small dc circuit breaker working voltage up to DC1000V, can rapidly points off the fault current of dc power distribution system, protect the important device in the solar system - pv module from reverse current and dc side due to the failure of the ac inverter feedback current, ensure the reliable operation of solar photovoltaic power generation systems.
