Phoenix Contact ST 4 Feed-Through Terminal Block Grey MPN 3031364

The Phoenix Contact ST 4 feed-through terminal block in grey is designed for secure and reliable electrical wire connections in industrial control panels, automation systems, and distribution boards. Built with spring-cage connection technology, this component ensures fast installation and optimal space utilization on standard DIN rails. It provides high contact quality and durability for professional electrical installations.

Advantages

The compact design combined with front connection technology enables user-friendly wiring even in restricted spaces. A consistent double function shaft offers efficient potential distribution and accommodates various test accessories to save time during setup. The large wiring space easily accommodates conductors with ferrules and plastic collars within the nominal cross section, ensuring reliable and flexible wiring options for demanding industrial environments.

Suitable for

• Industrial control panels and automation engineering
• Electrical distribution boards and junction boxes
• Wiring systems requiring space-saving DIN rail mounting
• Applications tested for railway standards

When it may not be suitable

This terminal block may not be suitable for high-current applications exceeding its nominal rating of 32 A or voltages above 800 V. It is also not intended for direct outdoor use without an appropriate weatherproof enclosure.

Key specifications

• Nominal voltage: 800 V
• Nominal current: 32 A
• Connection method: Spring-cage connection
• Number of connections: 2
• Conductor cross section: 0.08 mm² to 6 mm²
• AWG range: 28 to 10
• Width: 6.2 mm
• Color: Gray
• Mounting type: NS 35/7,5 and NS 35/15 DIN rails

How to use

Mount the terminal block securely onto a compatible standard DIN rail such as NS 35/7,5 or NS 35/15. Strip the insulation from the electrical conductor according to the specified requirements, and insert the wire into the spring-cage connection point until it is firmly seated. Utilize the double function shaft for potential distribution or testing purposes by inserting the appropriate accessories.

What to consider before purchase

• Verify that the operating voltage and current do not exceed 800 V and 32 A
• Check that your conductor cross section falls within the 0.08 mm² to 6 mm² range
• Ensure compatibility with standard NS 35 DIN rails in your control panel design

Usage recommendations: Always disconnect the power supply before installing or servicing electrical terminal blocks, and ensure conductors are correctly stripped and inserted to maintain a reliable connection.
