- 애플리케이션 & 작동 원리
적용범위: Used in distribution circuits with AC 45Hz~62Hz, rated voltage up to 500V and rated current up to 32A, serving as overload and short-circuit protection device.
작동 원리: When circuit overload or short circuit occurs, the melt inside the fuse link heats up and melts, cutting off the circuit to protect electrical equipment from damage.
메모: Not recommended for capacitor cabinets; replace with RT36 series if used for capacitor cabinets.

- 선택 포인트 & 대체 솔루션
선택 포인트
- 현재 매칭: Fuse link rated current shall be 1.1~1.5 times the rated current of protected equipment.
- 차단 용량: Ensure fuse breaking capacity ≥ circuit prospective short-circuit current.
- Dimension Matching: RT28N-32 base only fits 10×38mm fuse links; mixed use of other sizes is prohibited.
- Pole Selection: Select 1P (단상), 2피 (single-phase double-pole) or 3P (삼상) according to circuit phase.
- Indicator Requirement: Choose indicator type (RT28N-32X) if blown fuse indication is needed.
대체 솔루션
- Upgraded Same Series: RT28N-63X (applicable for fuse links below 63A, 교류 690V)
- Fast Fuse: RT36 series (for special occasions such as capacitor cabinets)
- Circuit Breaker Replacement: DZ47 series miniature circuit breaker (재사용 가능, with overload and short-circuit protection)
- 설치 & 유지 관리 지침
- Verify matching model of base and fuse link before installation; check fuse link for damage.
- Fasten the rail buckle during DIN rail mounting to avoid poor contact caused by looseness.
- Tighten terminals during wiring; conductor cross-section shall meet current requirement (2.5-4mm² copper wire recommended for 20A).
- Inspect fuse status regularly; lit indicator on indicator-type model means the fuse link is blown and shall be replaced timely.
- Cut off power supply and use insulated tools when replacing fuse link to avoid electric shock risk.
