Description

1.Product Overview

The Phoenix Contact ​1757022​ is a versatile terminal block designed for secure and efficient electrical connectivity in industrial automation systems. Part of Phoenix Contact’s industry-leading portfolio, this component ensures reliable signal and power transmission in control cabinets, machinery, and modular setups. Engineered for durability, it features a rugged housing resistant to mechanical stress and environmental factors like dust, vibrations, and temperature fluctuations. The terminal block supports both single- and multi-wire connections, making it adaptable to diverse wiring configurations. Its compact, space-saving design simplifies installation in high-density panels, while the transparent housing allows for visual inspection of connections without disassembly.

Compliant with international standards such as ​IEC 61131-2​ and ​UL 1059, the 1757022 is certified for global use. It is ideal for applications requiring stable electrical interfaces, including PLCs, motor controls, and sensor networks. Phoenix Contact’s focus on modularity ensures seamless integration with existing systems, reducing downtime during upgrades or maintenance.


2.​Key Technical Specifications

The 1757022 terminal block is defined by its robust technical parameters:

  • Rated Voltage: 300 V AC/DC
  • Current Rating: 17.5 A (maximum)
  • Wire Cross-Section: 0.08–4 mm² (fine-stranded) / 0.08–2.5 mm² (solid)
  • Temperature Range: -60°C to +100°C (operational), ensuring performance in extreme environments.
  • Contact Material: High-conductivity copper alloy with ​tin plating​ for corrosion resistance.
  • Insulation Material: Flame-retardant polyamide (UL94 V-0 rated), enhancing safety in high-risk settings.
  • Mounting: Compatible with DIN rails (EN 60715) for quick, tool-free installation.
  • Safety Standards: Meets ​IEC 60664-1​ (clearance/creepage distances) and ​UL 508​ (industrial control equipment).

These specifications ensure the terminal block’s suitability for high-current applications, such as power distribution and motor drives, while maintaining signal integrity in low-voltage control circuits.


3.​Primary Applications

The 1757022 is widely used in industrial automation for:

  • Power Distribution: Safely routes high-current signals in control cabinets and power supplies.
  • Sensor/Actuator Wiring: Connects sensors, switches, and actuators to PLCs or controllers.
  • Motor Control Interfaces: Links motor drives to control systems in manufacturing and robotics.
  • Modular Machinery: Supports flexible wiring in modular production lines and assembly stations.
  • Renewable Energy Systems: Integrates into solar inverters and wind turbine control panels.

Its versatility extends to sectors like automotive manufacturing, food processing (compliant with washdown environments), and infrastructure projects requiring reliable electrical connections. The terminal block’s DIN rail compatibility simplifies retrofitting in legacy systems, making it a cost-effective solution for modernization.


4.​Competitive Advantages

The 1757022 outperforms standard terminal blocks through:

  • Tool-Free Operation: Leveraging Phoenix Contact’s push-in technology, wires are secured without screws, reducing installation time by up to ​50%​.
  • Vibration Resistance: Spring-cage contacts maintain stable connections in high-vibration environments (e.g., heavy machinery or transportation systems).
  • Transparent Housing: Enables quick visual verification of wire seating, minimizing diagnostic downtime.
  • Scalability: Modular design allows easy expansion by interconnecting adjacent blocks.
  • Eco-Friendly Compliance: RoHS and REACH compliant, free from hazardous substances.

These features reduce maintenance costs, enhance system uptime, and future-proof installations against evolving automation demands.


5.​Functional Features

Functionally, the 1757022 excels in:

  • Multi-Wire Support: Accommodates up to four wires per terminal, optimizing space utilization.
  • High Current Capacity: Safely handles surge currents up to ​17.5 A, critical for motor starters and power relays.
  • Dual-Level Marking: Pre-printed and write-on labeling areas ensure clear circuit identification.
  • Test Point Integration: Built-in test sockets allow voltage/current measurements without disconnecting wires.
  • Polarization Options: Prevents accidental mismating in multi-pole configurations.

These functionalities make the 1757022 indispensable for engineers prioritizing reliability, safety, and ease of use in complex automation architectures.
