Product Title

CNC YCB8-63PV C63 63A 2-Pole 500V DC Solar MCB

Short Description

The CNC Electric YCB8-63PV C63 is a 63A, two-pole photovoltaic DC miniature circuit breaker rated for 500V DC. It provides isolation, overload and short-circuit protection with 6kA breaking capacity, thermomagnetic tripping, IP20 protection and IEC/EN 60947-2 compliance.

Long Description

Engineered for photovoltaic and other compatible DC distribution systems, the CNC YCB8-63PV combines a compact modular design with comprehensive circuit protection. CNC’s official selection table confirms that the two-pole configuration is rated at 500V DC, while the series supports current ratings up to 63A.

The C63 variant uses a C tripping characteristic and thermomagnetic release. Its 6kA ultimate breaking capacity and service breaking capacity equal to 100% of Icu support dependable interruption of DC fault currents when the breaker is correctly selected and installed.

The breaker supports standard DIN-rail installation and includes polarity markings for correct DC wiring. CNC officially lists isolation, overload and short-circuit protection and identifies photovoltaic, industrial, civil and communication systems among the intended applications. A qualified installer must confirm circuit polarity, voltage, continuous current, prospective fault current, cable sizing and protection coordination before installation.
