CNC YCB8-63PV 32A 2P 500V DC Solar MCB

Product Identification

Product Title

CNC YCB8-63PV 32A 2P 500V DC Solar MCB

Short Description

The CNC Electric YCB8-63PV 32A 2-pole DC miniature circuit breaker is designed for compatible photovoltaic and DC distribution systems. This 2P variant is officially rated at DC 500V and provides overload, short-circuit and isolation functions with 6kA ultimate breaking capacity, DIN35 rail mounting and IEC/EN 60947-2 compliance.

Long Description

Engineered for photovoltaic DC protection, the CNC YCB8-63PV offers a compact modular design for distribution boards and solar protection enclosures. The 32A, two-pole configuration uses series-connected poles for a rated operating voltage of DC 500V. Its polarized terminal markings must be followed during installation.

The breaker uses thermomagnetic tripping and supports overload, short-circuit and manual isolation functions. CNC officially specifies a 6kA ultimate breaking capacity, 1200V DC rated insulation voltage, 4kV impulse withstand voltage, IP20 protection and installation on a standard DIN35 rail. Selection and installation must be completed by a qualified electrical professional after checking system voltage, current, fault current, conductor size, polarity and installation conditions.
