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 Internal Structural Components of an AC Contactor form the foundational framework and mechanical actuation mechanism for industrial AC power contactors. This kit consists of a heavy-duty thermoplastic main housing frame paired with a precision-molded internal contact carrier rocker and a spring-assisted mounting latch assembly. Engineered to withstand high operational cycles, high temperatures, and electrical arcing, these components ensure precise alignment of power contacts and smooth movement during coil energization.
Multi-Phase Isolation Chambers: Features molded vertical phase barriers inside the frame to prevent phase-to-phase arcing and direct shorts during high-current switching.
Precision Pivoting Actuator Arm: Includes a durable nylon/PBT moving contact holder designed for seamless mechanical interlocking with the electromagnetic core assembly.
Spring-Loaded DIN Rail Latch: Built with a steel compression spring integrated directly into the rear base housing for quick, tool-free snap-on mounting to standard 35mm DIN rails.
High-Strength Thermal Polymer Construction: Molded using flame-retardant engineering plastics (PA66/PBT) for exceptional heat resistance, mechanical strength, and electrical tracking resistance.
Modular Assembly Design: Engineered with snap-fit slots, screw guide channels, and guided tracks to facilitate fast, repeatable assembly in automated production lines.
Product Type: Internal Structural Housing & Moving Carrier Component Assembly
Primary Components: Molded Outer Main Frame, Pivoting Contact Carrier Arm, Rear Spring-Loaded DIN Latch Mechanism
Materials: Flame-Retardant Thermoplastic (PA66 / PBT), Stainless Steel Spring
Color: Industrial Gray (Main Frame) & Light Cream / Off-White (Internal Carrier Arm)
Mounting Compatibility: Standard 35mm DIN Rail / Panel Screw Mount
Applications: AC Motor Starters, Modular Power Contactors, Lighting Control Relays, and Industrial Switchgear Assemblies
