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 Finished DC Power Contactor is a fully integrated, high-capacity electromechanical switching device designed for high-voltage DC circuits, energy storage systems, and industrial automation equipment. Combining heavy-gauge solid copper busbar terminals on the rear with finger-safe screw terminals on the front, this unit allows seamless plug-in connection to main busbars alongside easy control wiring installation. The unit is built to manage heavy electrical loads safely with minimal contact wear and fast arc extinction.
4-Pole Heavy-Duty Busbar Interface: Equipped with three rear heavy-gauge copper terminal prongs for direct, low-resistance connection to high-current distribution buses.
Finger-Safe Recessed Wire Terminals: IP20 touch-proof housing design with top and bottom screw clamps prevents accidental contact with live high-voltage conductors.
Front-Facing Auxiliary Actuator Array: Features five white mechanical status indicators and auxiliary drive triggers for quick status identification and system interlocking.
Advanced Internal Arc Suppression: Built-in dielectric phase separation barriers and internal arc chute chambers safely extinguish high-voltage DC arcs during current interruption.
Universal Mounting Base: Designed with integrated top panel-mounting ear holes and a rear DIN rail snap mechanism for flexible installation options inside switchgear cabinets.
Product Type: Fully Assembled Industrial DC Power Contactor
Pole Configuration: 4-Pole Main & Auxiliary Switching Assembly
Terminal Types: Rear Heavy Copper Busbar Plug-In Prongs & Front Recessed Screw Clamps
Housing Material: Flame-Retardant Glass-Filled Polymer (PA66 / PBT)
Mounting Style: 35mm DIN Rail Mount / Direct Panel Screw Mount
Applications: Battery Energy Storage Systems (BESS), Solar/PV Inverters, Electric Vehicle Charging Stations, DC Motor Controls, and Power Switchboards
