Engineered specifically for new energy power switch connections, the 5557-6P terminal wire harness integrates high-performance male-female connectors with precision wiring, delivering reliable power transmission for EV/HEV power control systems, energy storage devices, and industrial power switches. This 6-position (6P) solution features a 4.2mm industry-standard pitch, combining robust construction with optimized current-carrying capacity to meet the stringent requirements of new energy applications in high-voltage, high-vibration environments.
Core Features
✅ High-Power Transmission Capacity
9A rated current per contact (max 600V AC/DC) for demanding power switch applications
Supports 18-22AWG wires (0.32-0.82mm² cross-section) for flexible power distribution
Low contact resistance (≤20mΩ initial, ≤30mΩ after environmental testing) minimizes power loss
✅ New Energy-Grade Durability
PA66 nylon housing (UL94 V-2 flame-retardant) withstands -25℃ to 85℃ operating temperatures
Tin/gold-plated phosphor bronze contacts resist corrosion and ensure 500+ mating cycles
Vibration-resistant integrated locking mechanism prevents disconnection in vehicle/industrial environments
✅ Safety-Focused Design
Polarized housing with keyed alignment eliminates reverse connection risks for power switch systems
1500V AC withstand voltage (1 minute) ensures electrical safety in high-voltage new energy setups
Insulation resistance ≥1000MΩ prevents leakage and short-circuit hazards
✅ Seamless Integration & Installation
Wire-to-wire connection type compatible with standard 5557 series connectors and power switches
Color-coded wiring (red positive/black negative) simplifies polarity identification during assembly
Compact 4.2mm pitch design optimizes space utilization in power control cabinets
