3030349 - IP67 Quick-Connect - Industrial High-Current EMC Shielded - Rectangular Connector

Product Overview​

The Phoenix Contact ​3030349​ is a compact, high-performance relay interface module designed for secure signal amplification and electrical isolation in industrial control systems. Part of Phoenix Contact’s industry-proven RELAY series, this module bridges low-voltage control circuits (e.g., PLCs, sensors) and high-power loads such as motors, solenoids, or heaters. Its robust polyamide housing provides ​IP20 protection, ensuring resistance to dust and accidental contact, while the screw terminal design guarantees vibration-resistant connections. The module supports DIN rail mounting (EN 60715), enabling quick integration into control cabinets, motor control centers, and modular automation setups.

Engineered for versatility, the 3030349 features a transparent cover for visual status monitoring and complies with ​IEC 60947, ​UL 508, and ​RoHS/REACH​ standards. Its universal voltage compatibility (12–240 V AC/DC) makes it adaptable to diverse global applications, from manufacturing lines to renewable energy systems.

​Key Technical Specifications​

The 3030349 is characterized by precision-engineered performance metrics:

• ​Rated Voltage: 24–240 V AC/DC (control circuit) / 250 V AC (load circuit).
• ​Switching Current: 6 A (resistive) / 3 A (inductive), suitable for motors, valves, and lighting systems.
• ​Contact Configuration: SPDT (1 Form C) contacts for flexible switching operations.
• ​Isolation Voltage: 4 kV between coil and contacts, ensuring noise-free signal integrity.
• ​Operational Temperature: -40°C to +70°C, resilient in extreme industrial environments.
• ​Mechanical Lifespan: 10 million cycles, backed by gold-plated contacts for reduced arcing.
• ​Mounting: Tool-free DIN rail clip (35 mm rail compatible) for rapid installation.
• ​Certifications: UL 508, CE, cULus, and IEC 60947-5-1 (safety relays).

These specifications ensure reliability in high-demand scenarios, such as motor control and energy distribution.

​Primary Applications​

The 3030349 is indispensable in automation systems requiring robust signal conversion and load management:

• ​Motor Starters: Interfaces PLC outputs with motor contactors in manufacturing and robotics.
• ​HVAC Controls: Manages compressors, fans, and heating elements in building automation.
• ​Process Automation: Switches solenoid valves and pumps in water treatment or chemical plants.
• ​Energy Systems: Routes power in solar inverters, wind turbines, and battery management units.
• ​Safety Circuits: Integrates into emergency stop systems and safety relays for machinery protection.

Its compact design and high isolation voltage also suit railway signaling, packaging machinery, and semiconductor fabrication, where space efficiency and electrical noise mitigation are critical.

​Competitive Advantages​

The 3030349 outperforms conventional relay modules through innovative engineering:

• ​Universal Voltage Support: Operates across 12–240 V AC/DC, reducing inventory complexity.
• ​High Inrush Handling: Withstands surge currents up to ​45 A​ (20 ms), protecting sensitive electronics.
• ​Tool-Free Installation: DIN rail clip and screw terminals enable rapid deployment and reconfiguration.
• ​Visual Diagnostics: Transparent housing allows quick inspection of contact status without disassembly.
• ​Extended Durability: Gold-plated contacts and flame-retardant housing (UL94 V-0) ensure longevity.

These features minimize downtime, lower maintenance costs, and enhance system scalability.

​Functional Features​

The 3030349 delivers advanced capabilities for modern industrial automation:

• ​Electrical Isolation: Eliminates ground loops and electromagnetic interference (EMI) in control circuits.
• ​Fail-Safe Operation: Snap-action mechanism ensures reliable switching under load fluctuations.
• ​Modular Expandability: Daisy-chaining capability for cascading multiple units on a single DIN rail.
• ​Broad Compatibility: Works with Phoenix Contact’s SACC/SAC connector system for plug-and-play wiring.
• ​Custom Labeling: Write-on tabs for clear circuit identification and compliance with documentation standards.

Combined with Phoenix Contact’s rigorous quality assurance, the 3030349 is a trusted solution for engineers prioritizing precision, safety, and adaptability in mission-critical systems.
