Siemens 8WA1820 Terminal Block

Product Description

The SIEMENS 8WA1820 is a terminal block designed for organized, reliable wire termination in electrical control panels and distribution systems. Terminal blocks provide a secure connection point for multiple conductors, keeping wiring neat and simplifying circuit identification during installation and service. This unit ships one per pack and measures 3.110 inches long by 3.228 inches wide by 3.819 inches tall, making it suited for standard DIN rail or panel mounting layouts. Licensed electricians and panel builders typically specify this type of component during new construction, retrofit projects, and control panel fabrication work.

The 8WA1820 is appropriate for industrial control panels, commercial electrical distribution equipment, and building automation enclosures. It is well-suited for environments where multiple conductors must be terminated cleanly and identified easily. Panel builders, industrial electricians, and controls technicians working on motor control centers, PLC panels, and junction boxes will find this terminal block a straightforward fit for organized wiring schemes.

Key Features

• Compact form factor at 3.110 x 3.228 x 3.819 inches for efficient panel space use
• Single-unit pack quantity for individual or small-quantity procurement
• SIEMENS-manufactured for consistent quality in control panel applications
• Suitable for organized multi-conductor termination in industrial and commercial enclosures

Compatibility

Designed as an OEM-style replacement or direct-install terminal block for use in industrial control panels and commercial electrical distribution assemblies that accept standard SIEMENS 8WA-series terminal block components.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the panel before beginning termination work. Use appropriately rated hand tools for conductor stripping and terminal seating, and verify conductor gauge compatibility before terminating wires. Do not overtighten terminal screws, as this can damage conductor strands or the terminal body.
