Description
Product Overview
The Wago 2273 Series Direct Plug Terminal Block is engineered for modern electrical installations where space, speed, and safety are paramount. Constructed from high‑quality polymer housing, the block offers excellent insulation resistance and mechanical robustness, ensuring long‑term reliability even in demanding environments. Its compact dimensions—just 0.39 × 3.74 × 3.74 inches—allow it to fit into densely packed panels without sacrificing performance. The terminal block accommodates solid copper conductors ranging from 0.5 mm² to 2.5 mm², making it suitable for a wide variety of control, power, and signal wiring applications. With a rated voltage of 450 V and a current capacity of 24 A, the device can safely handle medium‑power loads while maintaining a low temperature rise.
The core innovation of the 2273 series lies in its direct‑plug insertion system. Users simply push the stripped end of the wire into the terminal, where a spring‑loaded clamp automatically grips the conductor, eliminating the need for additional tools such as screwdrivers or crimping devices. This mechanism not only speeds up assembly but also reduces the risk of human error, providing a consistent and repeatable connection quality. The optimized stripping length of 11 mm ensures that enough conductor is exposed for a secure electrical contact while minimizing the exposed length that could be vulnerable to accidental short circuits.
Designed for both industrial and domestic settings, the terminal block meets IEC 60947‑1 standards and carries CE certification, confirming its compliance with European safety and performance requirements. The product is supplied in a convenient bag of ten units, each labeled with clear polarity markings and color‑coded identifiers to aid rapid identification during installation. The robust design also includes a built‑in shielding feature that helps to reduce electromagnetic interference (EMI) in sensitive control circuits, further enhancing the reliability of the overall system.
Usage
Electrical engineers, automation specialists, and maintenance technicians will find the Wago 2273 terminal block an ideal choice for a broad spectrum of applications. In industrial automation, the block is frequently used to interconnect sensors, actuators, and programmable logic controller (PLC) I/O modules, where quick reconfiguration and reliable connections are essential for minimizing downtime. Its compact size makes it perfect for DIN‑rail mounted control cabinets, allowing more functions to be packed into limited space while preserving clear wiring organization.
In residential wiring, the terminal block simplifies the installation of lighting circuits, power outlets, and HVAC control panels. Home electricians appreciate the tool‑free insertion method, which reduces installation time and lowers labor costs. The block’s ability to handle both low‑voltage control signals and higher‑current power lines means it can serve as a versatile hub in smart‑home systems, integrating lighting control, security sensors, and energy‑monitoring devices.
The terminal block also excels in harsh environments such as factories with high vibration, temperature fluctuations, or exposure to dust and chemicals. Its polymer housing resists corrosion and provides a degree of protection against mechanical impact, while the spring‑clamp mechanism maintains a stable connection despite thermal expansion or contraction of conductors. For applications requiring frequent maintenance or circuit modifications, the quick‑release feature allows technicians to disconnect and reconnect wires without damaging the conductor or the terminal itself.

FAQ
Can the terminal block be used with stranded wires?
The 2273 series is optimized for solid conductors. While it may physically accept stranded wires, the spring‑clamp mechanism is designed to provide the most reliable grip on solid cores. For applications requiring stranded wire connections, Wago recommends using the 221 series, which is specifically engineered for that purpose.
What is the maximum temperature rating for the terminal block?
The polymer housing is rated for continuous operation up to 70 °C (158 °F). Short‑term exposure to higher temperatures is tolerated, but prolonged operation above the specified limit may affect the material’s mechanical properties and insulation performance.
Is the terminal block compatible with DIN‑rail mounting systems?
Yes, the 2273 series is designed for standard DIN‑rail installation. The block’s dimensions and mounting holes align with IEC 60715 specifications, allowing secure attachment to any compatible rail system without additional brackets or accessories.
How does the 11 mm stripping length improve safety?
The 11 mm stripped length provides enough exposed conductor for a solid electrical connection while limiting the amount of live wire that could be inadvertently touched or shorted. This balance reduces the risk of arcing, improves contact stability, and helps maintain consistent resistance across the connection.
What warranty does Wago offer for this product?
Wago provides a two‑year limited warranty covering material and workmanship defects under normal operating conditions. The warranty does not apply to damage caused by misuse, improper installation, or external factors such as extreme mechanical shock.
