LS ELECTRIC ABE404B-4P-400A is an economy 4-pole MCCB with 400A rated current and 10kA breaking capacity, suitable for low-voltage distribution systems with moderate breaking requirements. 더 높은 차단 용량용, use ABS (25그만큼) or ABH (35그만큼) 시리즈.

Applications of LS ELECTRIC ABE404B-4P-400A MCCB

코어 포지셔닝:

This 4-pole economy MCCB (4피, 400에이, 10그만큼) is mainly used for end protection in low‑voltage distribution systems, especially where neutral protection is required, short-circuit current ≤10kA, and budget is limited.

1. Commercial Building Distribution

일반적인 경우:

3–5 story office buildings, chain supermarkets, hotels as main or important branch breaker.

2. Industrial Plant Applications
3. 일반 기계

Main breaker for small‑medium production lines: 400A covers multiple branches; 10kA suits general industrial short-circuit levels

Motor group protection: Total power ≤200kW, used with thermal relays for precise protection

Auxiliary equipment: 팬, 슬리퍼, 압축기; 4P for control circuits with neutral

2. Specific Industries

Food processing: Cost-effective for light industry; 4P ensures safety and quality

전자 조립: 400A for multiple lines; 4P avoids neutral drift affecting precision equipment

Warehouse power: Main breaker for lighting and forklift charging

경고:

If short-circuit current >10그만큼, upgrade to LS ABS (25그만큼) or ABH (35그만큼).

3. Public & 주거용 건물
4. Education & Medical

School main distribution: 4P protects lighting, A/C, computer rooms; 400A for whole building

Community hospital: 4P for medical equipment with neutral; economy for primary care

Stadium auxiliary systems: Lighting, audio, seats; 400A for local zones

2. 하부 구조

Small wastewater treatment: 400A for pumps and blowers; 4P prevents control system failure

Urban landscape lighting: Main breaker for multi-loop lighting with reliable neutral

Small waste transfer station: 400A for compressors and conveyors; low operating cost

4. 특수 용도
5. Capacitor Bank Protection

For capacitor banks ≤100kvar; 4P prevents inrush and short-circuit during switching

Recommend adding SPD for surge protection

2. Small Generator Systems

Main breaker for generators ≤300kVA; 4P ensures safe isolation from grid

Used with synchronizing equipment for smooth switch between mains and generator

3. Temporary Power

Construction site temporary power main breaker; 400A for cranes, welders

4P suitable for harsh site conditions; prevents electric shock from broken neutral
