The TE Connectivity MA2.5/5.NT 1SNA125487R0600 is a compact blue 2.5 mm² neutral disconnect screw-clamp terminal block from the Entrelec SNA range, designed to simplify connection and disconnection of neutral circuits in industrial electrical panels. Its disconnect function allows neutral circuits to be isolated conveniently for testing, commissioning and maintenance without disturbing permanent field wiring.
The MA2.5/5.NT combines proven screw-clamp connection technology with a space-saving 5 mm terminal spacing. It accepts flexible conductors from 0.22–2.5 mm² and rigid conductors from 0.2–4 mm², making it suitable for compact control, automation and distribution-panel wiring.
Rated at 24 A and 400 V, with a rated impulse withstand voltage of 6000 V, the terminal provides dependable electrical performance for industrial applications. Its polyamide insulation, broad -55 to +110 °C operating temperature range and compatibility with G32 and TH35 DIN rails make it a versatile solution for professional panel building.
Neutral disconnect terminal blocks provide an efficient way to isolate neutral conductors during electrical testing, fault finding, commissioning and maintenance. The MA2.5/5.NT allows this isolation to be performed within the terminal assembly, helping technicians work on individual circuits without unnecessarily disturbing permanent wiring.
Its narrow 5 mm profile is particularly useful in densely populated control cabinets, while the blue insulation provides immediate visual identification of the neutral circuit. Screw-clamp technology and compatibility with several standard DIN rail profiles make the MA2.5/5.NT suitable for both new panel construction and maintenance of established industrial systems.
