Phoenix 3210156 PT 2,5-MT meracia oddeľovacia svorka, Push-in, sivá

In control cabinets and distribution boards where circuits must be safely isolated for testing and maintenance, the Phoenix 3210156 PT 2,5-MT measuring disconnect terminal block provides a reliable disconnect point. This grey, push-in terminal block allows you to separate the current path with a slide disconnect, insert a 2.3 mm test plug, and verify signals without disturbing the wiring. Its compact 5.2 mm width saves rail space, while the tool-free push-in connection speeds up installation for solid and stranded conductors up to 2.5 mm².

Why choose it

The push-in termination eliminates the need for special tools—just strip the conductor and push it in. The integrated disconnect slide gives you a visible, mechanical break in the circuit, making it easy to isolate sections for troubleshooting or commissioning. The grey polyamide housing is robust and flame-retardant, meeting UL 94 V0 for safety in industrial environments. Its narrow profile allows high-density wiring on the DIN rail without sacrificing functionality.

Ideal use cases

• Control panel building where test points are required for current or voltage measurement
• Signal distribution in automation systems needing quick disconnection for maintenance
• Machine building and plant engineering with frequent circuit isolation needs
• Retrofit projects where space is limited but disconnect functionality is essential

Good to know

The terminal block is designed for use with Phoenix Contact PT series accessories, including end covers, partition plates, and marking labels. It supports both solid and stranded conductors with ferrules, covering a wide range from 0.14 mm² to 2.5 mm² (stranded) and up to 4 mm² (solid). The test socket accepts standard 2.3 mm diameter test plugs, compatible with common multimeter leads. For reliable operation, ensure the DIN rail is properly grounded and the terminal is snapped securely onto the rail.
