Phoenix Contact PT 1,5/S-MT Grey Disconnect Terminal Block

The Phoenix Contact PT 1,5/S-MT Grey Disconnect Terminal Block is a professional-grade component designed for secure electrical wire connections and efficient circuit separation in industrial control panels and wiring systems. Engineered for reliability, this knife-disconnect terminal block facilitates safe testing and maintenance operations without the need to disconnect wiring completely. Its compact grey housing integrates seamlessly into standard DIN rail assemblies, making it a dependable choice for modern electrical engineering applications.

Advantages

This terminal block utilizes an advanced Push-in connection technology that significantly reduces wiring time and ensures a secure, vibration-resistant contact for solid and stranded conductors. The integrated knife-disconnect function allows technicians to isolate specific circuits quickly during commissioning, routine testing, or troubleshooting procedures. With its space-saving width and high-density mounting capabilities on standard DIN rails, it optimizes enclosure space while maintaining high electrical performance standards.

Suitable for

• Industrial control panels and automation systems
• Electrical distribution and wiring enclosures
• Signal and power circuit separation
• Maintenance and testing environments requiring quick circuit isolation

When it may not be suitable

This component is not designed for direct outdoor exposure without a proper protective enclosure. It is also unsuitable for wire cross-sections exceeding the specified 1.5 mm² limit or applications requiring higher current and voltage ratings beyond its technical specifications.

Key specifications

• Nominal voltage: 400 V
• Nominal current: 10 A
• Connection method: Push-in connection
• Conductor cross section: 0.14 mm² - 1.5 mm²
• AWG range: 26 - 14
• Width: 3.5 mm
• Length: 58.9 mm
• Color: Gray
• Mounting type: NS 35/7,5 and NS 35/15 DIN rails

How to use

To install the terminal block, snap it securely onto a compatible NS 35/7,5 or NS 35/15 DIN rail inside your control panel. Strip the appropriate length of insulation from the conductor and insert the wire directly into the Push-in connection point until it is fully seated. For testing or maintenance, use an insulated tool to open the knife-disconnect lever, safely interrupting the circuit without disturbing the surrounding wiring.

What to consider before purchase

• Verify that your conductor cross-sections fall within the 0.14 mm² to 1.5 mm² range.
• Check that the operating voltage and current do not exceed 400 V and 10 A.
• Ensure compatibility with standard NS 35 DIN rails in your enclosure.

Usage recommendations

Always ensure power is disconnected before installing or servicing the terminal block, and verify that all wire connections are securely seated according to the manufacturer specifications.
