Technical Overview

The Weidmüller AEP 2C 4 is a high-performance end plate engineered for A-series modular terminal blocks (specifically the A2C 4 line). Manufactured from Wemid, a specialized composite material, it provides critical electrical isolation and mechanical protection for the open side of the last terminal in a DIN-rail assembly. This component ensures compliance with finger-safe IP ratings and maintains necessary creepage and clearance distances to prevent short circuits. It features a robust snap-on mechanism with integrated locking pegs for secure, vibration-resistant mounting. With a UL 94 V-0 flammability rating and a continuous operating temperature range of -60°C to 130°C, the AEP 2C 4 is suitable for harsh industrial environments, including process control and automation applications.

Industrial Applications

1. Control Cabinet Safety Isolation

Installed at the terminating end of terminal block rows within high-density control cabinets to seal live components.

Problem Solved

Eliminates shock hazards by covering the open side of the final terminal block, ensuring IP20 finger-safe compliance and preventing accidental contact with live busbars.

Galvanic isolationIP20 complianceFinger-safe protectionArc flash prevention

2. Vibration-Proof Industrial Termination

Used in automated manufacturing lines to mechanically stabilize DIN-rail assemblies and maintain creepage distances between voltage groups.

Problem Solved

Prevents lateral movement of terminal blocks and maintains dielectric spacing in high-vibration environments, preventing short circuits due to component shifting.
