NS15

In the industrial automation and electrical distribution landscape, the NS15 series represents a category of high-performance molded case circuit breakers (MCCBs) designed for reliable overcurrent and short-circuit protection. These devices are typically available in 3-pole (3P) and 4-pole (4P) configurations, with rated currents ranging from 16A to 1600A, depending on the specific model. The NS15 breakers feature a compact design suitable for fixed or plug-in mounting, with breaking capacities up to 50kA at 415V AC. They incorporate thermal-magnetic or electronic trip units for precise protection coordination, and are compatible with a wide range of accessories such as shunt trips, undervoltage releases, and auxiliary contacts. The series is engineered for global use, operating at frequencies of 50/60 Hz and voltages up to 690V AC, making it a versatile choice for modern electrical systems.

The NS15 series is primarily deployed in low-voltage switchboards, motor control centers (MCCs), and distribution panels across various industrial sectors. Common applications include manufacturing plants, commercial buildings, data centers, and renewable energy installations like solar farms and wind turbines. These breakers are ideal for protecting feeders, motors, transformers, and capacitor banks, ensuring system stability and personnel safety. They are also used in marine and mining environments where robust performance under harsh conditions is critical. The series supports both main and branch circuit protection, with options for selective coordination to minimize downtime during faults.

Within the NS15 category, key subcategories include the NS15-160, NS15-250, NS15-630, and NS15-1600 models, each defined by their rated current and breaking capacity. The article codes typically follow a pattern like "NS15-160A-3P-50kA" or "NS15-250B-4P-36kA", where the number indicates the frame size, the letter denotes the trip unit type (e.g., A for thermal-magnetic, B for electronic), and the suffix specifies pole count and breaking capacity. Other notable variants include the NS15-N (standard performance), NS15-H (high performance), and NS15-L (very high performance) series, each tailored for specific fault current levels. Accessories like the NS15-MN undervoltage release and NS15-MX shunt trip are also integral to the range.
