PHOENIX PTME 4 Terminal Block Grey MPN 3212139

The PHOENIX PTME 4 Terminal Block Grey is a professional-grade test disconnect terminal block designed for secure electrical connections and testing applications in industrial control panels and wiring installations. This component provides reliable circuit separation and maintenance convenience for professional electrical engineering and automation systems, ensuring efficient operation and safe handling during system checks.

Advantages

This terminal block utilizes an advanced Push-in connection method that allows for tool-free insertion of rigid conductors and flexible conductors with ferrules, significantly reducing wiring time. The dedicated test disconnect functionality enables safe and fast measurements without requiring wiring disconnections, minimizing downtime during maintenance procedures. Its compact profile optimizes space inside control cabinets while accommodating a versatile wire cross section range, making it a reliable solution for complex electrical architectures.

Suitable for

• Industrial control panels and automation systems
• Electrical wiring installations requiring periodic testing
• Circuit separation and maintenance operations
• Control cabinet engineering with limited space

When it may not be suitable

This terminal block is not designed for direct outdoor installation without a proper protective enclosure, as it lacks weather and moisture resistance on its own. Additionally, it is unsuitable for electrical loads exceeding the specified nominal voltage and current limits.

Key specifications

• Nominal voltage: 500 V
• Nominal current: 24 A
• Connection method: Push-in connection
• Number of connections: 2
• Wire cross section: 0.2 mm² to 6 mm²
• AWG range: 24 - 10
• Width: 6.2 mm
• Height: 48.8 mm
• Color: Gray
• Mounting type: NS 35/7,5, NS 35/15 DIN rails

How to use

Mount the terminal block securely onto a compatible DIN rail such as NS 35/7,5 or NS 35/15 within the control panel. Strip the electrical wire to the recommended length and insert it directly into the Push-in connection point until it is firmly seated. Use the integrated test disconnect feature to isolate the circuit safely when performing measurements, diagnostics, or routine maintenance tasks.

What to consider before purchase

• Verify that the operating voltage and current do not exceed 500 V and 24 A.
• Ensure the available DIN rail type matches NS 35/7,5 or NS 35/15.
• Check that your conductor cross section falls within the 0.2 mm² to 6 mm² range.

Usage recommendations

Always disconnect the power supply to the control panel before installing, wiring, or servicing the terminal block to ensure maximum safety.
