Phoenix Contact ST 2,5 Feed-Through Terminal Block Grey MPN 3031212

The Phoenix Contact ST 2,5 feed-through terminal block in grey, model 3031212, is designed for secure and reliable electrical wire connections in industrial control cabinets and automation systems. This terminal block features efficient spring-cage connection technology that ensures vibration-resistant wiring, making it ideal for professional electrical installations where organization and high reliability are essential.

Advantages

The compact design and front connection layout save valuable space within control panels while enabling user-friendly wiring even in restricted areas. A consistent double function shaft provides extensive potential distribution options and accommodates various test accessories to streamline maintenance tasks. Additionally, the large wiring space easily accommodates conductors with ferrules and plastic collars within the specified nominal cross section.

Suitable for

• Industrial control cabinet wiring
• Automation systems and machinery manufacturing
• Professional electrical installations requiring vibration resistance
• Circuits demanding efficient potential distribution

When it may not be suitable

This terminal block may not be appropriate for applications requiring direct panel mounting without a standard DIN rail, as it is specifically designed for NS 35/7,5 and NS 35/15 mounting types. It is also not intended for high-voltage power distribution systems exceeding its rated voltage limits.

Key specifications

• Nominal voltage: 800 V
• Nominal current: 24 A
• Connection method: Spring-cage connection
• Number of connections: 2
• Conductor cross section: 0.08 mm² to 4 mm²
• AWG range: 28 to 12
• Width: 5.2 mm
• Color: Gray
• Mounting type: NS 35/7,5 and NS 35/15 DIN rails

How to use

Mount the feed-through terminal block onto a compatible DIN rail within your control cabinet. Strip the appropriate length of insulation from your conductor, insert it into the spring-cage connection point until fully seated, and ensure a secure hold. Use the double function shaft to insert bridging accessories for potential distribution or to connect test probes as required for your circuit configuration.

What to consider before purchase

• Verify that your conductor cross section falls within the 0.08 mm² to 4 mm² range
• Ensure your application operates within the 800 V and 24 A limits
• Check that your enclosure or cabinet utilizes compatible NS 35/7,5 or NS 35/15 DIN rails

Usage recommendations: Always disconnect power to the circuit before installing, wiring, or servicing the terminal block. Ensure that conductors are properly prepared and stripped to the manufacturer's recommended length to maintain a reliable and safe connection.
