Product Description

YCM8-400S PV 225A 250A 400A Photovoltaic DC 1000V 35KA 2P 3P 4P Molded Case Circuit Breaker MCCB

Product Description

General
 

YCM8-PV series photovoltaic special DC molded case circuit breaker is applicable toDC power grid circuits with rated voltage up to DC1500V and rated current 800A.
 

The DC circuit breaker has overload long delay protection and short circuitinstantaneous protection functions, which are used to distribute electric energy andprotect the line and power supply equipment from overload, short circuit and other

faults.

Features

Ultra-wide breaking capacity:

rated working voltage up to DC1500V and rated current up to 800A. Under DC1500V working conditions, Icu=Ics=20KA, ensuring reliable short-circuit protection.

Small size:

For frame currents up to 320A, the 2P rated working voltage can reach DC1000V,

and for frame currents of 400A and above, the 2P rated working voltage can reach

DC1500V.

Ultra-long arc-extinguishing chamber:the arc-extinguishing chamber has been improved as a whole, with more arc extinguishing plates, greatly improving the product's breaking characteristics.

Application of narrow-slot arc-extinguishing technology:advanced current-limiting and narrow-slot arc-extinguishing technology is applied,which enables the high voltage and high short-circuit current to be cut off very quickly, facilitating the extinguishing of the arc in the shortest possible time,effectively limiting the energy and current peak, and greatly reducing damage to cables and equipment caused by short-circuit currents.
