The Amphenol Industrial ELR4A03 / C10-737487-4AP3 is a premium EV connector belonging to the EPower Lite series. It is specifically engineered for hybrid and electric vehicle applications, providing robust power delivery and safety features required in automotive electrical systems. This RADSOK receptacle with HVIL (High Voltage Interlock Loop) is designed for female panel mounting, supporting up to 70A current at 800V.
The connector incorporates advanced RADSOK technology, offering low contact resistance and high amperage capability, which translates to lower temperature rise and voltage drop across the connection. Its compact, lightweight design and straight orientation make it ideal for installation in tight spaces within EV power control units, battery packs, or charging stations.
Build quality is highlighted by an IP67 waterproof rating, UL 94 V-0 flammability, and touch-proof dielectric protection to meet stringent automotive safety and reliability standards. The panel mount format with four contacts and two rows ensures high-density, secure cable management. The plastic housing is durable and resistant to environmental stresses, and the crimp termination allows fast, secure wire attachment, compatible with 6mm² wires.
Mis-mating and incorrect assembly are prevented by a correct key (Type A) and CPA (Connector Position Assurance) mechanism, which is essential for field installations and long-term maintenance. The operating temperature range from -40°C to 125°C supports usage in both cold and hot climates, further broadening possible deployment.
Applications include electric vehicle power distribution, battery pack connections, high-voltage control circuits, and renewable energy systems where robust connectivity is a must. Automotive manufacturers, EV assembly plants, and integrators will benefit from the modularity and performance of this connector.
Industry compliance is assured, with IEC 60529 and UL 94 V-0 certifications confirming its suitability for automotive and industrial use. The orange color housing offers visibility and safety marking typical in high-voltage component design. The product is manufactured in China and is intended for integration with the 4-position ePower-Lite plug with HVIL.
