1803578 - IP67 Quick-Connect - Industrial Auto Stainless High-Speed - Circular Connector

The Phoenix Contact 1803578 is a high-performance terminal block designed for secure electrical connections in industrial control and automation systems. Part of Phoenix Contact's CLIPLINE series, this component ensures reliable power and signal transmission in demanding environments such as manufacturing plants, energy distribution systems, and transportation infrastructure.

Its modular design allows for DIN rail mounting (EN 60715), enabling efficient integration into control cabinets and high-density installations. The terminal block features a durable polyamide housing with flame-retardant properties (UL94 V-0 rated), ensuring resistance to mechanical stress, heat, and chemical exposure.

Engineered for versatility, the 1803578 supports both single- and multi-wire connections, accommodating a wide range of conductor types. The transparent housing design facilitates quick visual inspection of wire seating, reducing maintenance downtime. Compliance with international standards like IEC 60947 and UL 1059 guarantees global applicability and safety.

• Rated Voltage: 300 V AC/DC
• Current Rating: 17.5 A (continuous), suitable for high-power applications
• Wire Cross-Section: 0.08-6 mm² (fine-stranded) / 0.08-4 mm² (solid conductors)
• Temperature Range: -60°C to +100°C (operational), ensuring performance in extreme conditions
• Contact Material: Tin-plated copper alloy for corrosion resistance and optimal conductivity
• Insulation Resistance: >1000 MΩ (at 500 V DC), minimizing leakage risks
• Mounting: Compatible with 35 mm DIN rails for tool-free, snap-on installation
• Certifications: UL 508, CE, cULus, and RoHS/REACH compliance

These parameters make the 1803578 ideal for high-current circuits, motor control panels, and power distribution systems.

• Motor Control Systems: Connects motor starters, VFDs (Variable Frequency Drives), and overload relays in manufacturing and robotics
• Power Distribution Panels: Routes high-current signals in switchgear and energy management systems
• PLC and Controller Wiring: Links sensors, actuators, and I/O modules to automation controllers
• Renewable Energy Installations: Integrates into solar inverters and wind turbine control units
• Transportation Infrastructure: Used in railway signaling and electric vehicle charging stations

Its vibration-resistant design and chemical-resistant housing also make it suitable for harsh environments like oil refineries, food processing plants, and mobile machinery.

• Tool-Free Installation: Push-in spring-cage technology enables fast, secure wire connections without screws or tools
• High Current Capacity: Safely handles surge currents up to 17.5 A, critical for motor starters and inductive loads
• Modular Scalability: Interlocking side walls allow easy expansion by connecting multiple blocks
• Transparent Housing: Simplifies visual inspection of connections, reducing diagnostic time
• Eco-Friendly Compliance: Halogen-free and RoHS-compliant materials align with sustainability goals

These features reduce labor costs, enhance system uptime, and ensure long-term reliability in mission-critical applications.

• Multi-Wire Support: Accommodates up to four conductors per terminal, optimizing space in control panels
• Test Points: Integrated test sockets enable voltage/current measurements without disconnecting wires
• Polarized Design: Prevents mismating in multi-pole configurations, ensuring error-free installation
• Vibration Resistance: Spring-loaded contacts maintain stable connections in high-vibration environments
• Dual-Level Labeling: Write-on tabs for clear circuit identification and documentation compliance

Combined with Phoenix Contact's rigorous quality control, the 1803578 is a trusted solution for engineers prioritizing safety, efficiency, and scalability in automation systems.
