Phoenix Contact 3036084 ST 2,5-PE/L/N Spring-Cage Terminal Block, Grey

The Phoenix Contact ST 2,5-PE/L/N spring-cage terminal block is a high-performance component engineered for secure and efficient electrical distribution in industrial environments. This three-level terminal block integrates protective earth, phase, and neutral connections into a single, space-saving unit, making it an essential choice for modern control cabinet wiring. Its robust spring-cage connection technology ensures reliable contact even under conditions of high vibration, while the compact design allows for high-density wiring configurations.

Advantages

The primary benefit of this terminal block is its integrated design, which combines three distinct functions into one housing, significantly reducing the amount of space required on the DIN rail. The spring-cage connection system provides a gas-tight and vibration-resistant contact that does not require maintenance or periodic tightening, unlike traditional screw terminals. Furthermore, the clear color coding and logical arrangement of the PE, L, and N levels facilitate error-free installation and simplify troubleshooting during maintenance tasks.

Suitable for

• Industrial control cabinets and automation systems
• Electrical distribution panels
• Applications requiring high-density wiring
• Systems subject to mechanical vibration

When it may not be suitable

This terminal block is not intended for high-power applications exceeding the specified nominal current of 22 A or voltages above 500 V. It is also not suitable for environments where the conductor cross-section exceeds 4 mm² or is smaller than 0.08 mm².

Key specifications

• Nominal voltage: 500 V
• Nominal current: 22 A
• Connection method: Spring-cage
• Number of connections: 6
• Cross-section range: 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 rails

How to use

To install the terminal block, snap it onto a standard NS 35/7,5 or NS 35/15 DIN rail. Strip the insulation from your conductors according to the recommended length and insert them into the spring-cage openings. The spring mechanism automatically clamps the wire, ensuring a secure electrical connection. Ensure that the PE, L, and N conductors are connected to their respective designated levels to maintain proper circuit functionality and safety standards.

What to consider before purchase

• Verify that the total current and voltage requirements of your circuit do not exceed the terminal block ratings.
• Ensure that your wire gauge falls within the specified 0.08 mm² to 4 mm² range.
• Confirm that your mounting rail type is compatible with the NS 35 standard.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring or maintenance on the terminal block to prevent electrical hazards. Use appropriate wire stripping tools to avoid damaging the conductor strands.
