Send us your technical drawings, samples, or exact panel specifications. We handle full tool/mold fabrication, precision polymer injection molding, and bulk delivery tailored strictly to your technical standards.
From initial spatial requirements and multi-tier structural design to DFM analysis, mold tooling, dielectric testing, and complete sub-assembly—we provide complete custom enclosure solutions ready for distribution.
The DC Contactor is a high-reliability electro-mechanical switching unit specifically engineered for DC power control, battery energy storage, and motor drive applications. Combining heavy-gauge rear busbar contact pins with front screw terminals, it enables rapid plug-in connection to main distribution buses while making auxiliary control wiring quick and secure. Its compact, fully enclosed body delivers excellent arc suppression and thermal stability during high-current switching.
Heavy-Duty Rear Plug-In Terminals: Features three solid copper busbar prongs for direct, low-resistance plug-in mounting onto main power distribution assemblies.
Finger-Safe Screw Terminals: Top and bottom recessed screw clamps protect operators from accidental contact with live conductors.
Front Access Auxiliary Interface: Equipped with dedicated auxiliary terminal ports and a visible mechanical position/label window for real-time status monitoring.
Arc Suppression System: Internal geometry designed to suppress and blow out high-voltage DC arcs, extending contact lifespan under heavy electrical loads.
Flame-Retardant Modular Housing: Enclosed in a dark gray, thermal-resistant industrial polymer housing built to endure heavy vibration and shock.
Product Type: Industrial DC Power Contactor / Switching Relay Module
Terminal Type: Rear Plug-In Busbar Prongs & Top/Bottom Screw Clamp Terminals
Housing Material: Flame-Retardant Engineering Polymer
Color: Dark Gray / Off-White Core
Applications: Battery Energy Storage Systems (BESS), Solar Inverters, Electric Vehicle Charging Infrastructure, DC Motor Drives, and Industrial Switchgear
