1.High voltage electrical control and protection
Overcurrent/overvoltage/undervoltage protection:
Integrated intelligent circuit breaker,multi-level protection threshold can be set(such as overcurrent protection divided into fast action(≤2ms)and delay action(10-100ms)to avoid false triggering).
Overvoltage protection response time≤5ms,undervoltage protection response time≤10ms,supports voltage fluctuation monitoring of AC/DC system.

It adopts a vacuum circuit breaker or air-tight contactor,supports manual/remote disconnection,with a breaking capacity of≥50kA(AC 25kV),meeting the extreme fail-off needs.
Isolation resistance≥1GΩ(5000V DC test)to ensure personnel safety during maintenance.
Short circuit protection:
Integrated fuse+electronic protection dual redundant design,after the fuse is fuse,it can alarm simultaneously through the LED indicator+communication interface,which facilitates rapid positioning of faults.
2.Signal monitoring and diagnosis
Multi-parameter monitoring:
Real-time acquisition of current,voltage,temperature,contactor status and other data,supports analog output(AO)and digital output(DO),and can be connected to the train monitoring system(TCMS).
Some models may integrate vibration sensors to monitor mechanical stress during operation of the equipment and prevent contacts from loosening.
Self-diagnosis and predictive maintenance:
Built-in microprocessor(MCU)analyzes current waveforms and temperature changes through algorithms,and predicts component life(such as the remaining life of the fuse and the wear of contactor contacts)in advance.
Supports fault code storage(≥100 items)and black box functions,record electrical parameters when the fault occurs,and assists in post-event analysis.
3.Communication and network integration
Multi-protocol compatible:
Supports CAN bus,MVB(multi-function vehicle bus),and Ethernet(TCP/IP),and can seamlessly connect to train network systems of different manufacturers.
Some models may integrate wireless communication modules(such as Wi-Fi/LTE)and support remote configuration and diagnosis(such as updating protection parameters through terrestrial servers).
Train network integration:
As a submodule of the traction control unit(PCU)or auxiliary power control unit(APCU),key information(such as pantograph status,traction motor current)is exchanged with the main controller through the process data object(PDO).
4.Enhanced environmental adaptability
Wide temperature and protection:
The operating temperature range is-55℃~+95℃,which is further expanded from previous generations(such as-50℃~+90℃of N897164610L),adapting to the Arctic Circle or the Middle East high-temperature desert environment.
Protection level IP68(dust-proof and waterproof),can be immersed in water for a short period of time(such as through water-stabilized sections)without damage.
Vibration and shock resistance:
IEC 61373 Category 3 Class B certification(previously Category 2 Class A),can withstand vibrations at higher frequencies(5-500Hz)and greater acceleration(10g),meeting the needs of maglev trains or heavy-duty railways.
Electromagnetic compatibility(EMC):
