Functional and Application Differences
- Core Differences:
NSX100F: Suitable for protecting load circuits with a maximum current of 100A or below, such as small motors, lighting distribution, and small distribution boxes.
NSX160F: Suitable for protecting load circuits with a maximum current of 160A, ideal for medium-sized motors, high-power equipment, and main distribution boxes.
- Trip Unit Compatibility:
– Both support thermomagnetic (TMD) and electronic (Micrologic) trip units.
– They share the same tripping characteristics and provide overload and short-circuit protection.
- Application Scenario Comparison:
NSX100F: Suitable for small industrial equipment, branch circuits in commercial buildings, and main distribution boxes in residential buildings.
NSX160F: Suitable for medium-sized industrial machinery, floor distribution boxes, small production lines, and scenarios requiring larger current capacity.
Рекомендации по выбору
– Choose NSX100F: When the maximum circuit current is ≤ 100A and switchgear space saving is required.
– Choose NSX160F: When the maximum circuit current is ≤ 160A, especially for current ranges between 100A and 160A.
Summary: И NSX100F, и NSX160F относятся к серии NSX компании Schneider Electric., со схожими основными технологиями и функциями. Ключевые различия заключаются в токе кадра. (100А против 160А) и физические размеры (ширина). Выбор следует определять на основе фактического тока нагрузки и пространства распределительного устройства..
