슈나이더 일렉트릭 ComPacT NSX160N

Schneider Electric’s ComPacT NSX160N is a high-performance 성형 케이스 회로 차단기 (MCCB), primarily used for overload protection, 단락 보호, and isolation functions in low-voltage power distribution systems.

Basic Parameters and Design

프레임 전류: 160에이 (adjustable range: 112-160에이)

차단 용량: 클래스 N (50그만큼), suitable for 380-415V AC systems; up to 90kA at 220V, and reduced to 10kA at 690V

극수: 3P or 4P (In the 4P model, the neutral wire (N) is located on the left; the 3D design indicates that the N wire is not involved in protection)

정격전압: 690뷔와 (50/60헤르츠), meeting the power distribution needs of most industrial and commercial applications

트립 유닛 유형: TMD (Thermomagnetic Trip Unit), 과부하 제공 (엘) and short-circuit (나) 보호, 포함:

과부하 보호 (그리고): Adjustable range of 0.7-1×In (160에이)

단락 보호 (ii): Fixed value of 1250A (약 7.8 정격 전류의 배)

구조 및 설치

설치 방법: Supports fixed, 플러그인, and withdrawable mounting, enabling flexible adaptation to different cabinet designs

전체 치수:

4P 모델: Width 140mm × Height 161mm × Depth 86mm, weight 2.6kg

3P 모델: The width may be narrower (105mm according to some data), and confirmation is required based on the specific model

연결 방법: Front connection design, with a terminal spacing of 35mm, 수평 또는 수직 설치 지원

III. Functions and Certifications

보호 기능:

기본형: Provides long-time overload (엘) and instantaneous short-circuit (나) 보호, IEC를 준수 60947-2 기준

Optional expansion: 누출 방지, undervoltage tripping, 원격 제어 (예를 들어, MX/MN coils) can be realized by adding modules

절연 기능: Complies with the EN/IEC 60947-2 standard and can be used as an isolator

환경 적응성:

작동 온도: -25°C ~ +70°C, 습도 ≤95% (결로가 없을 것)

인증: CCC, EAC, Marine certifications, 산업용으로 적합, 광고, and marine environments

응용 시나리오

배전 시스템: Used as a main switch or branch switch to protect circuits for motors, 조명, and mixed loads

산업 제어: Cooperates with devices such as contactors and relays to build automatic control circuits

재생에너지: Suitable for overcurrent protection in distributed generation systems such as solar energy and wind energy

Replacement and Upgrading

교체 모델: 더 높은 차단 용량용, NSX160H (70그만큼) or NSX160L (100그만큼) 선택할 수 있습니다

Digital Upgrading: The new generation of ComPacT NSX series (예를 들어, NSX160N-D) supports the EcoStruxure Power architecture and can integrate functions such as wireless monitoring, 에너지 계량, and service life prediction

선택 권장 사항
현재 매칭: Calculate the rated current (~ 안에) based on the load, and ensure that the trip unit setting covers the normal operating current
차단 용량: Select the breaking capacity class (N/H/L) according to the short-circuit current level at the installation location
액세서리 확장:

보조 연락처 (의): Used to indicate the status of the circuit breaker

Motorized Operating Mechanism (MT): Enables remote switching on and off

누출 모듈 (비고 NSX): Provides residual current protection

Ⅶ. 지침

설치사양: Must comply with IEC 60947-2 and local electrical installation standards, and ensure that the terminal torque meets the requirements

유지 관리 권장 사항: Regularly inspect the contact wear condition; clean the arc-extinguishing chamber and test the tripping characteristics every 2-3 연령
