GE SR469 469-P5-HI-A20-E
Product Overview
The GE SR469-P5-HI-A20-E is a high-performance intelligent motor management relay developed by GE Multilin, officially released in the early 2000s as a core device of the Multilin 469 series. Designed for medium and large industrial AC motor equipment, this integrated protection and monitoring unit integrates electrical protection, operational metering, condition monitoring and fault recording functions in a compact panel-mounted structure. Optimized for heavy industrial harsh environments, it adopts a dedicated DSP digital processing chip and nonlinear thermal protection algorithm, supporting long-term 24-hour stable operation. After decades of global industrial field verification, it has become a standard configuration for key motor equipment safety protection and is widely used in system maintenance and renovation projects.

Core Product Features
The SR469-P5-HI-A20-E supports comprehensive motor protection logic, covering overload thermal protection, phase unbalance protection, locked rotor protection, overcurrent and undercurrent protection, effectively avoiding common motor burnout and mechanical damage faults. It features a 5A secondary CT rating, compatible with mainstream industrial current transformer specifications, and supports primary current adaptation from 1A to 5000A for diverse motor power levels. Equipped with universal wide-range AC/DC dual power supply, it adapts to complex and unstable industrial power supply conditions without additional voltage conversion modules. The built-in thermal memory function and nonlinear thermal model accurately record motor heat accumulation state, preventing false tripping and repeated start failure. It also integrates high-speed fault waveform recording function, which can record voltage and current waveforms before and after faults, providing accurate data support for fault analysis and equipment maintenance.

System Compatibility & Technical Advantages
This motor management relay features excellent industrial system compatibility and can be seamlessly connected with industrial PLC, DCS and SCADA monitoring platforms, realizing real-time remote data transmission, parameter configuration and equipment status monitoring. The HI configuration version is optimized for high-induction industrial working conditions, with stronger anti-interference and environmental adaptability than ordinary versions. Adopting industrial-grade electromagnetic shielding and surge protection design, it resists strong electromagnetic interference and power grid fluctuation in factory environments. The compact integrated structure simplifies on-site installation, wiring and debugging work, reducing engineering and maintenance costs. As a mature and stable classic model with long-term market verification, it has ultra-low failure rate and excellent replaceability, being the preferred spare part for aging motor protection system upgrade and maintenance.
