5.2 Non-recommended Applications
直流回路: Select dedicated Emax DC series (e.g.E1N-DC)
Installation above 2000m altitude without current derating
Frequently switching loads: Adopt contactor + thermal overload relay combination instead
Severe environment with Pollution Degree 4: Extra enclosure protection required
5.3 代表的な応用例
Case1: Main Distribution for Automobile Manufacturing Plant
応用: Secondary-side main protection for 10kV/0.4kV factory transformer (1600あ)
構成: E1N16-R1600-PR121-LSI 3P fixed type with PR121/P-LSI trip unit
パフォーマンス: Realizes long-delay overload, short-delay & 瞬時短絡保護; forms selective coordination with downstream MCCB to limit fault outage area and improve power supply reliability.
Case2: UPS Output Distribution in Large-scale Data Center
応用: Main protection for 2000kVA UPS outgoing terminal
構成: E1N16-R1600-PR121-LSI 4P fixed type plus communication module for remote monitoring
アドバンテージ: Low power consumption reduces UPS loading; optimized protection curve avoids unintended UPS tripping under short-circuit; communication function enables early fault alert & 遠隔診断.
