£2.53
The TE Connectivity / Entrelec 1SNA400814R0000 is a compact and reliable MA2.5/5-CPE pluggable feed-through terminal block designed for secure conductor connections in industrial control panels, machinery and automation systems. Part of the established Entrelec pluggable terminal block range, it combines screw-clamp wiring with a detachable connection system to simplify installation, maintenance and equipment integration.
This grey terminal block provides a single feed-through circuit and is designed for DIN rail mounting. Its pluggable construction is particularly useful in equipment containing multiple assemblies, allowing electrical connections to be disconnected and reconnected without unnecessarily disturbing permanent panel wiring. The screw-clamp connection provides a dependable mechanical and electrical connection for industrial conductors.
With a nominal conductor cross-section of 2.5 mm², an IEC rated current of 12 A and rated voltage of 320 V, the MA2.5/5-CPE is suited to signal, control and power distribution applications. Its narrow 5.08 mm spacing helps maximise wiring density within electrical cabinets while maintaining convenient access for installation and servicing.
Pluggable terminal blocks provide a practical way to create modular electrical connections between control-panel wiring and removable machine or equipment assemblies. The detachable connection arrangement allows circuits to be separated efficiently during installation, commissioning or servicing while retaining organised DIN rail wiring inside the cabinet.
The MA2.5/5-CPE combines this flexibility with proven screw-clamp termination technology. Its compact dimensions, broad conductor capacity and compatibility with common DIN rail formats make it well suited to industrial automation, machine building and electrical panel applications where dependable connections and efficient use of cabinet space are important.
