Suntree DC MCB 4Pole 1000v 63A, 32A, 20A

The Suntree 4-Pole DC MCB is designed to meet the rigorous demands of modern high-voltage solar installations. In many large PV systems, voltages can reach up to 1000VDC, which presents unique challenges for circuit protection, particularly regarding the suppression of DC electric arcs. This 4-pole breaker addresses this by distributing the electrical load across four contact points, significantly increasing the arc voltage and ensuring a safe, rapid disconnection when a fault is detected. It is suitable for a variety of applications, with frame degree rated currents available in 16A, 32A, and 63A options. The device is built to operate reliably at a rated operating voltage of DC 1000V, providing a critical shield for your inverters, charge controllers, and battery banks. Beyond its functional performance, the Suntree MCB is constructed from high-quality, flame-retardant materials that withstand the thermal stresses of continuous solar power generation. Its compact footprint allows for efficient use of space within electrical panels, while the mechanical design ensures thousands of reliable switching cycles. By integrating this 4-pole breaker, installers can ensure their systems comply with international safety standards for high-voltage DC circuits, minimizing the risk of equipment damage or fire. Whether used in a residential rooftop setup or a commercial solar farm, this breaker offers the professional-grade reliability required for sustainable energy systems.
