6. 항공 운송 규정 준수 & 인증정보

6.1 Air Shipment Compliance Judgment

제품 카테고리: Electrical and electronic equipment (내장 리튬 배터리 없음 / 슈퍼 커패시터)

UN 번호: 필요하지 않음 (위험하지 않은 물품)

Shipping Restrictions: No special restrictions, deliver as general cargo

포장 요구 사항: Adopt anti-static packaging to avoid static damage to internal components during transportation

6.2 인증정보

메모: CE marks and certification numbers are marked on product body and outer package. Technical documents shall include test reports, risk assessment reports and Declaration of Conformity (DoC), which shall be kept for at least 10 연령.

7. 선택 공식 & Quick Memorization Rules

7.1 선택 공식

Calculate motor current first, match EOCRSSD properly;

05 stands for 0.5-6A, 30 covers 3-30A;

60 reaches 60A, match external CT for higher current;

Select S/W according to control power, S means 24-240 넓은 전압;

Three core protections: 초과 적재, phase loss and stall;

Easy fault checking via digital display, convenient DIN rail installation.

7.2 Quick Memorization Rules

현재 매칭: Rated motor current shall be within 30%-80% of protector range, avoid boundary value affecting accuracy

전압 선택: Prioritize Type S (24-240V AC/DC) control power for stronger compatibility

매개변수 설정:

O-TIME: 세트 10-20 seconds when current is 1.2 모터 정격 전류의 배

D-TIME: Set as motor startup time plus 2 초

Replacement Rule: Realize 1:1 direct replacement for traditional EOCR-SS series and thermal relays without changing installation size and wiring

8. 해당되는 & 적용할 수 없는 시나리오

적용 가능한 시나리오

1. General Industrial Motors: Protection for water pumps, 팬, compressors and other common equipment
2. 소규모 생산 라인: Single motor control loop requiring visualized fault display
3. Renovation Projects: Replace traditional thermal relays to improve protection precision and convenience
4. Harsh Working Environment: Temperature range -20℃~60℃, suitable for most industrial sites
5. Multi-voltage System: 24-240V wide voltage adaptation, fit for transnational equipment and complex power supply environment

적용할 수 없는 시나리오

1. High-precision Control: Intelligent control system needing 4-20mA analog output or communication function (Recommend EOCR-E series)
2. Extra-high Current Motor: Current over 60A without space for external CT installation (Recommend EOCR-3DM2 series)
3. Special Protection Demand: Occasions requiring earth protection, leakage protection or phase sequence protection (Recommend EOCR-DS1 series)
4. Explosion-proof Environment: Hazardous areas needing explosion-proof certification (Choose dedicated explosion-proof protectors)
