STD11-125 IEC60947.2 DC Current MCB Circuit Breaker Long Using Life

STD11-125 series DC Miniature Circuit Breaker can quickly break the fault currents in DC power distriubtion systems, Especially for the DC system of power projects in measurement and protection screen and electrica screen between leapfrong tripping accident, the series has excellent performance, and avoid the occurence of the fault. The products can protects the solar photovoltaic power generation in the important devices in PV module from high DC reverse current and due to failure of the inveter AC feedback current hazards, to entrue the reliabel operation of solar photovoltaic power generation system. It is used on building and similar places the line facilities of over current portection , can also be used in less frequent break operation. And has small volume , breaking capacity, arcing distance is short, fast closing and installation is convenient.

Rated voltage(Ue): DC 24,48,120,250,500,750,1000

1. Application:For protecting cables and equipments against overload and short circuit.

2. General rules for choosing MCB.

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.

2. 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.)
