The 63A DC Circuit Breaker MCB is a high-quality solar panel protection device designed for PV systems, off-grid solar installations, and DC electrical circuits. This 2-pole (2P) DC MCB ensures reliable over-current protection for solar arrays, inverters, and DC load circuits, safeguarding your equipment against short circuits, overloads, and electrical faults.

Engineered specifically for DC applications, this circuit breaker is suitable for direct current control circuits where branch circuit protection may already exist or is not required. Its robust design supports a rated voltage of 600VDC and a breaking capacity of 6kA, providing stable and secure protection for residential, commercial, and industrial solar systems.

The 63A DC MCB is compliant with IEC60947-2 standards, guaranteeing high performance and safety in all operating conditions. It features a C-type characteristic curve, ideal for solar panel protection, sensitive to sudden current surges while preventing nuisance tripping. Designed for durability and reliability, it operates effectively within a working temperature range of -5℃ to +40℃.

This DC circuit breaker has a mechanical life of over 20,000 cycles and an electrical life of at least 8,000 operations, making it suitable for long-term solar PV system applications. With IP20 enclosure protection, it ensures safe handling and minimal exposure to dust or accidental contact.

Ideal for solar energy systems in Bangladesh, this 2P DC MCB is perfect for residential, commercial, and industrial solar PV installations, providing reliable circuit protection and contributing to the overall safety and efficiency of your solar power system.
