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 Contactor Upper Housing Assembly is a high-precision, injection-molded enclosure component designed to house moving contacts, arc chutes, electromagnet coils, and terminal connections in industrial power contactors. Built with flame-retardant thermoplastics, it protects internal electrical mechanisms while providing total phase-to-phase insulation and optimal thermal airflow during high-current operations.
3-Pole Terminal Isolation Chambers: Molded with individual phase barriers and wire access windows to prevent phase short circuits and arcing between live power connections.
Optimized Thermal Vents & Ribs: Integrated side and bottom cooling fins release heat buildup, ensuring long component life during continuous switching cycles.
Precision Internal Guide Rails: Built-in internal grooves allow easy, snap-in installation for auxiliary contact blocks, armature springs, and control board assemblies.
Dual Mounting Capability: Designed with bottom mounting ear holes and a rear clip structure to support both DIN rail snapping and direct screw panel mounting.
High-Impact Dielectric Polymer: Manufactured from heavy-duty engineering plastic providing superior flame resistance, tracking resistance, and mechanical strength.
Product Type: Contactor Upper Housing / Relay Frame Enclosure
Material: Flame-Retardant PA66 / PBT / ABS Plastic
Color: Industrial Light Gray
Mounting Type: 35mm DIN Rail / Screw Mounting Base
Applications: AC Contactors, Motor Starters, Power Relays, and Industrial Automation Control Panels
