Product Description

Product Description

General

YCB8s-63PV photovoltaic dedicated DC circuit breaker is mainly used in solar photovoltaic power generation systems.
The maximum working voltage can reach DC1500V, and the

rated current is up to 63A.
It is used for overload and short circuit protection of the line, and can quickly cut off the fault current of the DC distribution system, protecting the important components in the solar power generation system, ensuring the reliable operation of the solar photovoltaic power generation system.

standards:IEC60947-2

Accessories
The following accessories are suitable for YCB8s-63PV series, which can provide the functions of remote control of circuit breaker, automatic disconnection of fault circuit, status indication (breaking/closing/fault tripping).



a.   The total width of the accessories assembled is within 54mm, the order and quantity from left to right: OF, SD(3max) + MX, MX+OF+MCB, SD can only assemble up to 2 pieces ;
b.   Assembled with the body, no tools required;
c.   Before installation, check whether the technical parameters of the product meet the requirements of use, and operate the handle to open and close several times to check whether the mechanism is reliable.

Miniature circuit breaker accessories
•     Auxiliary contact OF
Remote indication of closing/opening status of circuit breaker.
•     Alarm contact SD
When the circuit breaker fault trips, it sends out a signal, together with a red indicator on the front of the device.
•     Shunt release MX
When the power supply voltage is 70%~110%Ue, the remote control circuit breaker trips after receiving the signal.
•     Minimum making and breaking current: 5mA(DC24V)
•     Service life: 6000 times (operating frequency: 1s)
