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

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

Ключевые различия

1. SUPER MAGNET technology: Equipped only on SC-N6 and above, enabling AC/DC dual compatibility, wide voltage, низкое энергопотребление, and chattering-free operation
2. Rated current and capacity: Increase stepwise with frame size
3. Endurance: SC-N3 has longer mechanical life (10 миллион раз) 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

Рекомендуется: LC1D115M7C (Катушка переменного тока 220 В) + LADN22 (2NO+2NC aux), fully matches SC-N6 performance and contacts

2.2 Siemens Alternative Models

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

2.3 Mitsubishi Alternative Models

Alternative models: S-N125 / S-K125

Ключевые параметры: 3П, 125А (АС-3), 30кВт(240В)/55кВт(440В), 2NO+2NC aux

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

3. Notes on Cross-Brand Replacement
4. Широкая совместимость по напряжению: SC-N6’s SUPER MAGNET is unique; most Schneider/Siemens equivalents use fixed-voltage coils. Select coil voltage according to actual power supply
5. Конфигурация вспомогательных контактов: SC-N6 includes 2NO+2NC standard; most competitors supply 1NO+1NC, requiring additional modules
6. Монтажные размеры: Dimensions vary by brand; verify installation space before replacement
7. Operating frequency and endurance: SC-N6 mechanical endurance 5 миллион, электрический 1 миллион (АС-3); replacements should meet or exceed these values
8. Control circuit design: If system uses SC-N6’s dual AC/DC feature, ensure new contactor coil matches control power
9. Заключение

The Fuji SC-N6-DC24-AC220V offers unique advantages in industrial automation thanks to SUPER MAGNET technology: wide voltage compatibility, низкое энергопотребление, и высокая надежность. For cross-brand replacement, Schneider LC1D115 series or Siemens 3RT2036 series with auxiliary modules are recommended to match electrical performance and functions.
