DC MCB Circuit Breaker 4P 63A 1500V DC – CNC

The CNC DC miniature circuit breaker (DC MCB), model YCB8s-63PV, is an advanced protection device designed specifically for high-voltage photovoltaic (PV) systems. Rated for up to 1500 V DC and 63 A, this four-pole breaker provides reliable, instant protection against short circuit and overload, keeping solar panels, inverters and batteries safe under the toughest operating conditions.

⚡ Features:

Dedicated solar (PV) protection: engineered to protect solar panel strings and system components from damage caused by reverse or excess currents.

Very high operating voltage (DC 1500V): handles very high DC voltages, making it ideal for large commercial and industrial solar systems.

Four-pole design (4P Heteropolarity): its heteropolar design ensures safe and complete disconnection in complex systems, with highly efficient extinguishing of DC arcs.

Fast response (K curve): the K-type trip curve reacts very quickly to short-circuit currents, giving maximum protection to sensitive equipment.

Durable and safe: made of heat-resistant, flame-retardant engineering plastics for stable performance and a long service life.
