About the CHIYT 125A DC MCB 1000V 2P NBT2-125DC High Current Solar & Battery Circuit Breaker

<h3>CHIYT NBT2-125DC 2P 125A 1000V DC High-Current Circuit Breaker</h3> <p>The <strong>CHIYT NBT2-125DC</strong> is a high-amperage, industrial-grade 125A DC miniature circuit breaker engineered specifically for high-capacity LiFePO4 battery banks, high-power hybrid inverters (5kW – 15kW), and commercial solar photovoltaic arrays operating up to 1000V DC.</p> <h4>Engineered for High-Current DC Systems:</h4> <ul> <li><strong>10kA Heavy-Duty Breaking Capacity:</strong> High-current DC circuits generate powerful electric arcs that cannot be quenched by standard AC breakers. The NBT2-125DC incorporates magnetic arc blow-out chutes and de-ion plates to extinguish DC faults safely.</li> <li><strong>Dual Protection for Battery &amp; Inverter Lines:</strong> Safely isolates 48V/51.2V lithium battery banks and high-voltage DC solar combiner strings from destructive short circuits and overcurrent heat.</li> <li><strong>Pure Copper Terminals:</strong> Accommodates heavy-gauge battery cables (up to 35mm² / 2 AWG) with minimal contact resistance and zero thermal hotspots.</li> <li><strong>20,000 Cycle Longevity:</strong> Built with robust internal mechanical mechanisms conforming strictly to IEC 60947-2 industrial safety standards.</li> </ul>

Distributed officially by Shamim Traders Solar Division, this unit undergoes strict pre-dispatch quality inspection and serial number warranty verification. Equipped with advanced MPPT tracking algorithms, intelligent thermal management, and robust protection circuitry against high voltage surges, power grid transients, and tropical monsoon moisture.
