安装与维护
安装建议：
垂直安装于通风良好的控制柜内，留出至少80mm散热空间。
主回路母排需采用铜排连接，接触面涂导电膏（推荐凡士林+银粉混合膏）。
维护周期：
每半年检查触点弹簧压力，压力值需≥0.5N（使用弹簧秤测量）。
每年清理灭弧罩积碳，使用压缩空气吹扫时压力≤0.3MPa。
故障处理：
若接触器粘连，立即切断电源并检查线圈电阻，正常值范围15Ω±5%。
高湿度环境需定期检测辅助触点绝缘电阻（要求≥10MΩ）。

Part 3:Product details
Core positioning
EATON NBDC31000MW is a”high-power energy gate”designed for heavy industrial motor control systems.Through the 3000A rated current carrying capacity and IP66 protection design,it solves the contact ablation and control failure of traditional contactors in high load and dusty environments,and meets the strict needs of large motors,transformers,and power system main circuit control.
Technical parameters
Model:NBDC31000MW
Rated current:3000A(AC 600V)
Control voltage:24V DC(compatible with 12V DC)
Auxiliary contacts:8 sets(NO/NC optional)
Mechanical life:10 million times
Electrical life:1 million times(3000A/AC 600V)
Protection level:IP66
Working temperature:-25℃~+60℃
Certification:CE,UL,RoHS
Core advantages
High current bearing:Copper alloy contacts+silver tin oxide coating are used,3000A continuous operation does not generate heat,and the contact oxidation rate is reduced by 60%.
Dust-resistant design:IP66 protection+labyrinth sealing structure,adapted to high-dust environments such as metallurgical plants and mines.
Dual control compatibility:supports 12V/24V DC dual voltage control,adapted to different PLC systems.
Redundant contacts:8 sets of auxiliary contacts can expand secondary control functions such as alarm and interlock.
Wide temperature range adaptation:-25℃~+60℃work stably,and no additional heating device is required in the north in winter.
Typical Applications
Metallurgical industry:blast furnace blower and steel rolling machine main motor control
Power system:transformer opening and closing,high-voltage capacitor group turn-off
Mining equipment:power switching of mine hoist and crusher
Port machinery:container crane,door machine,truck motor drive
New energy:wind turbine pitch system,energy storage battery pack charging and discharging control
Installation and maintenance
Installation suggestions:
Install vertically in a well-ventilated control cabinet,leaving at least 80mm of heat dissipation space.
The main circuit busbar needs to be connected by copper strips,and the contact surface is coated with conductive paste(recommended Vaseline+silver powder mixed paste).
Maintenance cycle:
Check the contact spring pressure every six months,and the pressure value must be≥0.5N(measured with a spring scale).
Carbon deposits are cleaned every year for arc extinguishing hoods,and the pressure is≤0.3MPa when purged with compressed air.
Troubleshooting:
If the contactor is stuck,immediately cut off the power supply and check the coil resistance,the normal value range is 15Ω±5%.
High humidity environments require regular detection of auxiliary contact insulation resistance(required≥10MΩ).
