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

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

Key Differences

1. SUPER MAGNET technology: Equipped only on SC-N6 and above, enabling AC/DC dual compatibility, wide voltage, 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 de milioane de ori) 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

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

2.2 Siemens Alternative Models

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

2.3 Mitsubishi Alternative Models

Alternative models: S-N125 / S-K125

Key parameters: 3P, 125O (AC-3), 30kW(240V)/55kW(440V), 2NO+2NC aux

Diferenţă: 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
5. Auxiliary contact configuration: SC-N6 includes 2NO+2NC standard; most competitors supply 1NO+1NC, requiring additional modules
6. Dimensiuni de montaj: Dimensions vary by brand; verify installation space before replacement
7. Operating frequency and endurance: SC-N6 mechanical endurance 5 million, electric 1 million (AC-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. Concluzie

The Fuji SC-N6-DC24-AC220V offers unique advantages in industrial automation thanks to SUPER MAGNET technology: wide voltage compatibility, low power consumption, și fiabilitate ridicată. Pentru înlocuirea între mărci, Schneider LC1D115 series or Siemens 3RT2036 series with auxiliary modules are recommended to match electrical performance and functions.
