Durable plug in type installing 30A 3pole MCB cbi 3 phase Circuit Breaker 110V ,240V


Plug- in mounting MCB Circuit Breaker 75A High Breaking Capacity IEC60947.2 Standard comply with southern American market


General


STXW series high breaking capacity mini circuit breaker (MCB) protect electrical circuits against overload and shortcircuit current. They provide ON-OFF switching easily. MCB is applicable to electric circuits with rated voltage 230/400V AC, frequency 50/60Hz and rated current up to 75Amp. The product provides protection against overload and short circuit to electric circuits and equipments in household and commercial installations. MCB is also used as non-frequent changeover of electric circuits.


  1. Technical data of the network at the point considered

The earthing systems,short-circuit current at the circuit breaker installation point,which must always be less than the breaking capacity of this device,network normal voltage.

  1. There are 3 curvve characteristics for magnetic operation:

B curve (3-5In) protection and control of the circuits against length cables in TN and IT systems.

C curve (5-10In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.

D curve (10-14In) protection and control of the circuits against overloads and short-circuits; protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers,breakdown lamps.)
