Comparison of Fuji SC-N Series Contactors and Cross-Brand Selection Reference

1. Key Parameter Comparison Table for Fuji SC-N Series Models

الاختلافات الرئيسية

1. SUPER MAGNET technology: Equipped only on SC-N6 and above, enabling AC/DC dual compatibility, الجهد واسعة, low power consumption, and chattering-free operation
2. Rated current and capacity: Increase stepwise with frame size
3. Endurance: SC-N3 has longer mechanical life (10 مليون مرة) due to no electronic control, but same electrical life as SC-N6
4. Coil characteristics: SC-N6/N12/N16 use electronically controlled coils with wide voltage input; SC-N3 uses fixed-voltage coils
5. Alternative Models for SC-N6 from Major Brands

2.1 Schneider Alternative Models

مُستَحسَن: LC1D115M7C (لفائف AC220V) + LADN22 (2NO+2NC aux), fully matches SC-N6 performance and contacts

2.2 Siemens Alternative Models

مُستَحسَن: 3RT2036-1AG20 + 3RH6122-1AP00, matches current, سعة, and 2NO+2NC configuration

2.3 Mitsubishi Alternative Models

Alternative models: S-N125 / S-K125

Key parameters: 3ص, 125أ (ايه سي-3), 30كيلوواط(240V)/55كيلوواط(440V), 2NO+2NC aux

اختلاف: Fixed-voltage coil only; no wide voltage DC24V–AC220V support

3. Notes on Cross-Brand Replacement
4. Wide voltage compatibility: SC-N6’s SUPER MAGNET is unique; most Schneider/Siemens equivalents use fixed-voltage coils. Select coil voltage according to actual power supply
