|---|---|
The SC6-63 series, also known as the DZ47-63A Miniature Circuit Breaker (MCB), is a compact, high-performance electrical protection device engineered for AC 50/60Hz power systems. With rated voltages of 230V/400V and rated currents up to 63A, it provides essential overload protection and short circuit protection for residential buildings, commercial spaces, industrial infrastructure, and energy sector applications. Compliant with IEC 60898-1 standards, this MCB also serves as an infrequent line switching device under normal conditions. Featuring thermo-magnetic release technology with trip curve options (B/C/D) and current-limiting technology, it delivers precise current control and fast fault interruption, while its magnetically blown arc extinguishing device minimizes electrical hazards. Its compact design and user-friendly features make it a top choice for modern electrical systems.
Equipped with a sensitive thermo-magnetic release, the SC6-63 MCB detects overload currents and trips within specified timeframes (e.g., ≤1h for 1.13In at In≤63A), preventing circuit overheating and fire risks.
With a rated breaking capacity of 6000A~10000A and a magnetically blown arc extinguishing device, the MCB rapidly interrupts short circuits, limiting fault current duration and protecting connected appliances and equipment.
Available in trip curve types B (3-5In), C (5-10In), and D (10-20In), the SC6-63 adapts to diverse loads: Type B for sensitive electronics, Type C for residential lighting/sockets, and Type D for motor circuits—ensuring optimal protection for every scenario.
The MCB features clear contact position indication (red for closed, green for open), a non-slip handle for easy operation, and an anti-mistake contact terminal block to prevent incorrect wiring. Its flame-retardant, impact-resistant housing enhances operational safety.
Offered in 1P/2P/3P/4P pole options, the SC6-63 supports versatile wiring setups. It installs seamlessly on 35mm DIN rails (per EN 60715) via a fast-clip device, with top/bottom cable/busbar connections for hassle-free integration.
Boasting an electrical life of 8000 cycles and mechanical life of 20,000 operations, the DZ47-63A MCB ensures reliable performance in high-use environments. Its IP20 protection degree and operating temperature range of -5℃~+40℃ (daily average ≤35℃) guarantee stability.
