Product Identification

Product Title

CNC YCB8s-63PVn C20 20A 2P 600V DC Solar MCB

Short Description

The CNC YCB8s-63PVn C20 is a 20A, two-pole photovoltaic DC miniature circuit breaker designed for overload and short-circuit protection in solar DC distribution systems. This non-polar model is rated for DC600V operation and offers a standard 6kA ultimate short-circuit breaking capacity in a compact DIN-rail format.

Long Description

Protect critical solar DC circuits with the CNC YCB8s-63PVn C20 photovoltaic miniature circuit breaker. Engineered specifically for DC applications, this 20A two-pole breaker simultaneously disconnects both conductors and supports non-polar wiring, allowing supply connection from either the upper or lower terminals.

The breaker combines overload and short-circuit protection with manual circuit isolation. Its C-curve tripping characteristic suits correctly engineered DC circuits where controlled tolerance of normal transient current is required. The verified 2P configuration operates at up to DC600V, carries an IP20 protection rating and conforms to IEC 60947-2.

For safe selection, the breaker rating must be coordinated with the PV string, cable size, system voltage, prospective fault current and equipment manufacturer requirements. Installation should be completed by a qualified electrical professional.
