MQ*5, MQ*5 (DZ*7 C*5 C*5) MINI CIRCUIT BREAKER MCB

1.      APPLICABILITY

MQ*5, MQ*5 Mini Circuit Breaker is suitable to be used in overloading and short circuit protection at *0/*0 Hz and rated voltage **0/**0V and rated current *3V and in normal situation while the lines are no frequently transformed.

The Breaker is often used in industry, commerce and multi – storage buildings and civil housing constructions, according with the standard of GB*********9 and coming up to the international advance standard.

2.      FRATURES

(1)   High ability if separating in rated short circuit the rated electric current of all the products car be over *6KA. MQ*5H**3 over *0KA, DZ****0(cover *0A), is only 4KA.

(2)   Double connection function. It can conveniently connect busbar and flexible or inflexible conducting wire.

(3)   Energy storage structure. The point of contacting can be quickly closed. Which can prevent the unfavourable influncence caused by the low speed of manual operation. Therefore, it’s life span is greatly enhanced.

(4)   It has the combined junction terminal with self protection function at touching, which enhances the safety.

(5)   The cover and some components are made of imported high burning – proof , hear resisting and lash proof plastic.

(6)   High circuit limitation parameter, comparing with DZ*7, it’s performance and price are better.

(7)   On the handle of MQ*5H**3, is carved with green stripe, which can clearly indicate the connection point is really in the breaking position.

(8)   The endurance of MQ****3 at high charging has been enhanced to 6KV.
