## Long description

The Phoenix Contact ST 1.5-TWIN is a professional-grade feed-through terminal block engineered for reliable electrical connectivity within industrial control cabinets and automation systems. With a slim 4.2 mm profile and a rated voltage of 500 V, this component is designed to optimize space while maintaining high performance in signal and power distribution circuits.
Advantages
The primary benefit of this terminal block is its advanced spring-cage connection technology, which allows for rapid, vibration-resistant wiring without the need for specialized tools. The TWIN design enables the connection of two conductors to a single potential, significantly simplifying complex wiring layouts and reducing the need for additional bridging components. Its compact dimensions ensure high packing density on DIN rails, making it an ideal choice for space-constrained control panels.
Suitable for
Industrial automation and control systems
Signal distribution in electrical cabinets
Power distribution for low-voltage circuits
Applications requiring vibration-resistant connections
This terminal block may not be suitable for applications involving high-current power distribution exceeding its rated capacity or for environments requiring specific hazardous area certifications not covered by its standard specifications. It is also not intended for direct outdoor exposure without a protective enclosure.
Key specifications
Rated voltage: 500 V
Connection method: Spring-cage connection
Width: 4.2 mm
Color: Grey
Conductor cross-section compatibility: Suitable for fine-stranded and solid conductors
To use the terminal block, mount it onto a standard DIN rail by snapping it into place. Strip the insulation from your conductor to the recommended length, then insert the wire into the spring-cage terminal point. The internal spring mechanism automatically secures the wire, ensuring a consistent and reliable contact pressure that remains stable even under mechanical stress or vibration.
What to consider before purchase
Ensure the rated voltage and current match your circuit requirements
Verify that the conductor cross-section is compatible with the terminal capacity
Confirm that the DIN rail type in your cabinet is compatible with the mounting style
Usage recommendations: Always ensure that the power supply is disconnected before performing any wiring operations. Use appropriate wire stripping tools to avoid damaging the conductor strands, and verify that all connections are fully seated to maintain optimal electrical integrity.
