The NLM3DC-250/2P DC Molded Case Circuit Breaker is a specialized 250A DC MCCB designed for DC power systems—including photovoltaic (PV) systems, battery energy storage, and industrial DC networks. As a high-performance DC molded case circuit breaker, it features a 2-pole structure engineered to handle DC-specific challenges, such as high fault current interruption and stable operation under continuous DC loads. Unlike AC breakers, the NLM3DC-250/2P DC MCCB addresses the unique demands of DC power, ensuring safety in applications where standard AC solutions fall short. Manufactured via intelligent automated lines, it delivers consistent quality and durability, making it a top choice for modern DC energy systems.
A key strength of the NLM3DC-250/2P DC Molded Case Circuit Breaker is its high DC breaking capacity. It safely interrupts high fault currents in solar and energy-storage systems, preventing equipment damage and maintaining system stability. This capability is critical for DC networks, where fault currents are harder to interrupt than AC—making the 250A DC MCCB an essential safety component.
The NLM3DC-250/2P DC MCCB has a compact molded-case design that optimizes panel space—ideal for PV inverters, energy storage cabinets, and space-constrained DC systems. Despite its small size, it offers high thermal stability and mechanical durability, supporting long-term heavy-load operation. This balance of compactness and strength ensures the DC molded case circuit breaker fits diverse installations.
All NLM3DC-250/2P DC MCCB units are produced on advanced smart lines, with automated assembly, strict performance testing, and aging checks. This process guarantees consistent quality across every unit, minimizing performance variations and enhancing reliability. Customers can trust the 250A DC MCCB to meet strict standards, reducing unexpected failures in critical DC systems.
The NLM3DC-250/2P DC Molded Case Circuit Breaker adapts to a range of DC voltage levels, making it suitable for PV power plants (with varying voltage tiers) and battery energy storage systems (BESS) with different voltage needs. This adaptability ensures the DC molded case circuit breaker integrates into diverse DC networks.
Even in continuous high-temperature environments—common in sun-exposed PV installations or industrial DC facilities—the NLM3DC-250/2P DC MCCB maintains stable tripping performance. It detects faults accurately without temperature interference, ensuring reliable protection for DC systems in challenging climates.
In PV power plants, the NLM3DC-250/2P DC Molded Case Circuit Breaker protects solar panels, inverters, and DC lines from fault currents. Its temperature resistance and high breaking capacity make it ideal for outdoor/rooftop installations, ensuring efficient, safe operation.
BESS requires reliable DC protection to safeguard batteries and power conversion equipment. The 250A DC MCCB prevents overloads and short-circuits, protecting batteries and ensuring safe energy storage/discharge cycles.
Telecom networks rely on DC power for servers and communication devices. The NLM3DC-250/2P DC MCCB protects telecom DC cabinets from faults, ensuring uninterrupted communication services.
Electric vehicle (EV) charging stations use DC for fast charging. The DC molded case circuit breaker safeguards charging equipment and connected EVs from faults, enhancing user and operator safety.
