New Energy Power parts Chassis distribution box assembly 3771110-KT6A0

Designed with NEV-specific safety needs in mind, this assembly incorporates a multi-layer protection system to safeguard the vehicle’s power distribution. The outer casing is built with an IP67 waterproof and dustproof rating, preventing water, dust, or road debris from entering the box—critical for chassis-mounted components exposed to harsh driving conditions. Internally, it features overcurrent protection (via high-quality fuses and circuit breakers) that automatically cuts off power when current exceeds safe limits, avoiding damage to expensive electrical parts like inverters or batteries. It also includes insulation barriers made of flame-retardant PC (polycarbonate) material, which resists high temperatures (up to 120°C) and prevents electrical arcing, reducing the risk of fire. These safety features meet international NEV standards (e.g., IEC 60664), ensuring compliance with global safety regulations

Constructed from premium materials to withstand the rigors of NEV chassis environments, the assembly’s main casing uses high-strength aluminum alloy—offering excellent corrosion resistance (via an anodized surface treatment) and structural rigidity, while remaining lightweight to minimize chassis load. Internal terminals and connectors are made of copper alloy with tin plating, ensuring low electrical resistance (≤0.01Ω) for efficient power transmission and preventing oxidation over time. The assembly undergoes precision manufacturing processes: CNC machining for the mounting frame ensures dimensional accuracy, while automated soldering for wiring connections guarantees consistent quality. Each unit also undergoes a 100% pressure test and electrical performance check before leaving the factory, ensuring it can withstand long-term vibration (up to 50Hz) and temperature fluctuations (-40°C to 85°C) without performance degradation

This distribution box assembly is optimized for efficient power management in NEVs, featuring a modular design that separates high-voltage (HV) and low-voltage (LV) circuits—preventing interference between different power systems. It supports a wide input voltage range (200V–800V), making it compatible with most NEV battery configurations (e.g., pure electric, plug-in hybrid). The internal layout is designed for maximum wiring efficiency: pre-labeled terminals and color-coded connectors simplify identification, while ample space for wire routing reduces cable stress. It also integrates with the vehicle’s BMS (Battery Management System) and VCU (Vehicle Control Unit), enabling real-time monitoring of power distribution status—allowing the NEV to adjust power flow dynamically and improve energy efficiency. This compatibility and efficiency make it suitable for a range of NEV models, from passenger cars to light commercial vehicles

Engineered for user convenience, this assembly features a hassle-free installation design that reduces repair time. It comes with pre-assembled mounting hardware (bolts, washers) and a detailed installation guide with wiring diagrams, allowing technicians to install it in 30 minutes or less—no specialized tools required. The casing has a snap-on cover with a quick-release latch, enabling easy access to internal components for maintenance (e.g., fuse replacement) without disassembling the entire assembly. Additionally, the modular design means individual components (e.g., terminals, fuses) can be replaced separately, reducing maintenance costs compared to integrated distribution boxes. To ensure reliability, the product is backed by a 36-month warranty against manufacturing defects, and its corrosion-resistant materials minimize the need for frequent maintenance—making it a cost-effective choice for NEV owners and fleet operators
