Weidmuller WAP 2.5-10 BL End Plate

Technical Overview

The WAP 2.5-10 BL is a specialized end plate manufactured by Weidmüller, designed specifically for the W-Series, Z-Series, and compatible modular terminal block systems. Constructed from Wemid, a proprietary thermally stable composite, this component provides critical electrical isolation and mechanical closure for the open side of the final terminal in a rail assembly. The unit features a specific blue coloration, typically utilized to identify neutral conductors or intrinsically safe circuits within control cabinets. It ensures compliance with finger-safety standards (IP20 when installed), maintains voltage ratings by preserving creepage distances, and offers robust performance with a continuous operating temperature range of -60 °C to 130 °C.

Key Features

Industrial Applications

1. Terminal Stack Mechanical Termination

Installed as the final component in a DIN rail terminal block assembly to physically cover the open side of the last terminal.

Problem Solved

Prevents accidental human contact with live internal busbars (ensuring IP20 finger safety) and protects internal metal parts from dust and debris ingress.

2. Intrinsically Safe Circuit Identification

Leverages industry-standard blue coloration to visually segregate specific circuit types within a high-density control panel.

Problem Solved

Provides immediate visual distinction for neutral conductors or intrinsically safe (Ex i) circuits, reducing maintenance errors and simplifying compliance inspections.

3. Dielectric Clearance Maintenance

Establishes a physical dielectric barrier at the end of the terminal strip to enforce required air and creepage distances.

Problem Solved

Ensures the assembly maintains its full rated voltage insulation coordination against adjacent metallic enclosure walls or other components, preventing arcing.
