These terminal blocks are designed for easy installation, secure connections, and compact integration in control panels, distribution boards, and various industrial applications.

Here’s a detailed description of its features and specifications:

Key Features:

Type:

The UK5 RD-E (also known as the UK5NRD-E) is part of the UK 5 series of terminal blocks from Phoenix Contact. These terminal blocks are two-level, feed-through blocks, ideal for connecting electrical conductors in control cabinets and enclosures.

Design:

These are rail-mounted terminal blocks, designed to be installed on a DIN rail (typically 35mm rail).

The blocks have screw connections, ensuring that wires are securely fastened and have reliable electrical contacts.

Transparent covers (optional) are available for some versions, allowing for easy visibility of the internal wiring for maintenance and troubleshooting.

Connection Capacity:

Each UK5 RD-E terminal block is designed to accommodate conductor sizes from 0.08 to 6 mm² (28 to 10 AWG). This makes it suitable for a wide range of wire gauges commonly used in industrial and control applications.

The terminal block is designed for use with solid, stranded, and flexible conductors, providing versatility in connection options.

Features of the RD-E Version:

The RD-E variant is specifically designed for cross-connection, allowing for easy bridge connections between adjacent terminal blocks. This is useful for simplifying wiring in control panels and electrical distribution systems.

The UK5 RD-E is typically used in applications where the electrical circuits need to be grouped together for common connection points.

Color and Material:

The standard color of the terminal block is typically gray, making it easy to identify and organize in control systems.

The body is made from high-quality insulating material (typically polyamide or similar durable materials) to ensure safety and durability in industrial environments.

Flame-resistant properties are also standard, meeting various industrial safety standards.

Box Packaging:

The terminal blocks are supplied in a box containing 50 pieces, which makes it ideal for bulk purchasing and large projects where multiple terminal blocks are needed for wiring setups.

The individual packaging of terminal blocks helps in organizing and preventing damage during transport and storage.

Ease of Installation:

The snap-on mounting feature ensures quick and easy installation onto a DIN rail, minimizing installation time and simplifying maintenance tasks.

Screw-type connections ensure that the wires are securely fastened and provide a reliable electrical contact.

The blocks are maintenance-friendly, offering quick access to the wiring and the ability to replace individual blocks as needed.

Applications:

Control Cabinets: Used for wiring and organizing control signals, power lines, and data connections.

Industrial Automation: Used in PLC (programmable logic controller) wiring, industrial machines, and control circuits.

Electrical Distribution: Ideal for building distribution boards, power distribution systems, and electrical panels.

Signal Distribution: Common in control panels where signal lines need to be grouped together for cross-connection or centralized distribution.

Current Rating:

The terminal block has a current rating of up to 20A, depending on the conductor size used. It can handle moderate current loads typical for control and automation systems.
