## Summary description

The Phoenix Contact ST 2,5-3L (3036042) is a high-quality three-level terminal block designed for efficient electrical wiring. Featuring spring-cage connection technology, it supports conductor cross-sections from 0.08 to 4 mm². This grey terminal block is ideal for space-saving installations in industrial control cabinets and automation systems, ensuring reliable and secure connections for complex circuitry.

## Long description

The Phoenix Contact ST 2,5-3L is a high-performance three-level terminal block engineered for professional electrical installations where space optimization is critical. Utilizing advanced spring-cage connection technology, this terminal block allows for rapid and reliable wire termination without the need for specialized tools. Its compact design incorporates three distinct connection levels within a single housing, significantly increasing wiring density in industrial control cabinets and automation panels.
Advantages
The primary benefit of this terminal block is its ability to maximize cabinet space by stacking three independent circuits in a narrow 5.2 mm footprint. The spring-cage connection system provides excellent vibration resistance and maintains constant contact pressure over time, ensuring long-term operational reliability. Furthermore, the design allows for individual labeling on every level, which simplifies circuit identification and maintenance tasks in complex electrical systems.
Suitable for
Industrial control cabinet wiring
Automation and process control systems
High-density electrical distribution panels
Complex circuitry requiring multi-level signal routing
When it may not be suitable
This terminal block is not intended for high-power applications exceeding 20 A or voltages above 500 V. It is also not suitable for environments requiring specialized hazardous area protection unless installed within an appropriately certified enclosure.
Key specifications
Connection method: Spring-cage connection
Number of levels: 3
Nominal voltage: 500 V
Nominal current: 20 A
Conductor cross-section: 0.08 mm² to 4 mm²
AWG range: 28 to 12
Width: 5.2 mm
Mounting type: NS 35/7,5 or NS 35/15 DIN rail
How to use
To install, snap the terminal block onto a standard NS 35 DIN rail. Strip the insulation from your conductor to the recommended length and insert the wire into the spring-cage terminal point. The spring mechanism automatically secures the wire, providing a gas-tight connection. To remove or adjust the wire, use a standard screwdriver to depress the spring release. Ensure that all connections are fully seated and that the terminal block is properly labeled for future reference.
What to consider before purchase
Verify that the DIN rail type in your cabinet is compatible with NS 35 standards.
Ensure the conductor cross-section falls within the 0.08–4 mm² range.
Check if the 500 V and 20 A ratings meet your specific circuit requirements.
Confirm that you have sufficient space for the 5.2 mm width per terminal block.
Usage recommendations
For optimal performance, ensure that wires are stripped to the manufacturer's specified length and that the DIN rail is securely mounted. Use appropriate marking materials to label each level clearly to facilitate efficient troubleshooting and maintenance.
