DETAILED DESCRIPTION

The WAGO 274 Series is an electrical connection system consisting of interlocking through connectors with levers. Individual modules can be combined to create terminal strips with exactly the number of poles required or used as preassembled multi-pole terminal strips.

The series includes 2-conductor and 4-conductor modules as splicing connectors or feed-through terminal blocks, as well as accessories for mounting, potential distribution and conductor retention.

What Are the Benefits of the WAGO 274 Series?

Key Benefits:

Greater flexibility and design freedom: Individual modules can be combined to provide exactly the number of poles required for the application.

Reduced wiring effort: Push-in CAGE CLAMP® and WAGO lever technology enable fast, tool-free connection of all conductor types.

Improved process reliability: Spring-pressure connection technology provides secure, maintenance-free conductor termination. Color coding, custom lever labeling and preconfigured terminal strips help reduce wiring errors.

Worldwide applicability: International certifications support use in a wide range of markets and applications.

What Does the WAGO 274 Series Offer?

Many applications require specialized terminal strips that are difficult to realize using standard products. With the WAGO 274 Series, users can assemble exactly the terminal strip they need for their application, whether on-site, during the assembly of components and machinery, or for device wiring.

How the WAGO 274 Series Works

WAGO's 274 Series is based on two interlocking modular components:

2-Conductor Through Connector: Conductor cross-section: 0.2 to 4 mm², 24 to 12 AWG

4-Conductor Through Connector: Conductor cross-section: 0.2 to 2.5 mm², 24 to 14 AWG.

Both modular through connectors with levers can be snapped together side-by-side. This allows terminal strips with different numbers of poles to be assembled. In addition, preassembled, multi-pole terminal strips with 2 to 8 poles are available. Both modular through connectors with levers are available as splicing connector and feed-through terminal block variants. WAGO's modular 274 Series through connectors with levers are available in two versions: splicing connectors (white base) and feed-through terminal blocks (gray base).

Splicing Connectors (Identified by a white housing base)

What Can WAGO 274 Series Terminal Strips Be Used For?

Application Examples for Modular Through Connectors with Levers

Many applications require different connection configurations. Standard terminal strips are often either unsuitable or provide more poles than actually required. With the 274 Series, terminal strips can be assembled from individual modules, allowing the number of poles to be tailored to the specific wiring task. Typical applications include:

• Heat pumps
• Indoor and outdoor lighting
• Air-conditioning systems
• Commercial dishwashers
• Ventilation systems
• Roller shutters and awnings
• Utility service connection points
• Lighting loop-through applications
• Industrial electric motors
• Sensors, such as motion and presence detectors

How Are Terminal Strips Configured for Series Production?

Terminal strips for applications with consistent wiring requirements can be configured using the WAGO Smart Designer Configurator. Configuration options include:

• Various pole counts
• Combination of 2-conductor and 4-conductor modules
• Color coding
• Lever markings
• Potential distribution
• Mounting solutions
• PE contacts

This allows terminal strips to be delivered preconfigured for the specific application.
