Product Overview
The Phoenix Contact 3003347 is a high-reliability plug-in connector designed for secure signal and power transmission in industrial control systems. Part of Phoenix Contact’s COMBICON series, this component ensures robust connectivity in automation environments such as control cabinets, motor control centers, and modular machinery. Its compact, modular design supports DIN rail mounting (EN 60715), enabling space-efficient integration into high-density panels. The connector features a durable polyamide housing with IP20 protection, providing resistance to dust and minor mechanical impacts.
Engineered for versatility, the 3003347 accommodates both single- and multi-conductor wiring, making it suitable for diverse applications ranging from PLC interfaces to sensor networks. Compliance with IEC 60947, UL 1059, and RoHS/REACH standards ensures global applicability and adherence to environmental regulations. The push-in spring-cage clamping technology allows tool-free installation, reducing assembly time and minimizing wiring errors. Transparent housing enables quick visual inspection of wire seating, simplifying maintenance in complex systems.
Key Technical Parameters
The 3003347 is defined by precision-engineered specifications for industrial durability:
- Rated Voltage: 250 V AC/DC
- Current Rating: 4 A (continuous), optimized for low-power control circuits.
- Wire Cross-Section: 0.14–0.75 mm² (fine-stranded) / 0.2–0.5 mm² (solid conductors).
- Temperature Range: -40°C to +85°C (operational), ensuring stability in harsh environments.
- Contact Material: Tin-plated copper alloy for low resistance and corrosion resistance.
- Insulation Resistance: >100 MΩ (at 500 V DC), minimizing leakage risks.
- Mounting: Compatible with 35 mm DIN rails for tool-free, snap-on installation.
- Safety Certifications: UL 94 V-0 (flammability), CE, and cULus listed.
These parameters make the 3003347 ideal for signal routing, sensor networks, and low-voltage control systems.
