1586526

Overview

The Phoenix Contact 1586526 is a COMBI plug component designed for electrical interconnection within terminal block systems. It features a single pole configuration with a 5.2 mm pitch, accommodating rigid or flexible conductors ranging from 0.25 mm² to 1.5 mm². The unit supports a nominal voltage of 500 V and a rated current of 17.5 A. Constructed with a left housing and quick connection technology, it complies with IEC 61984 standards for load-free switching. The component utilizes a green-yellow color scheme and offers overvoltage category III insulation with a 6 kV surge withstand voltage.

Feature Summary

• Quick connection technology enables tool-free wiring for rapid assembly
• COMBI design allows for load-free connection and disconnection per IEC 61984
• Left housing structure facilitates specific spatial integration in control cabinets

Applications

• Industrial control cabinet wiring
• Signal distribution in automation systems
• Connection of sensors and actuators

Procurement Notes

Verify the complete part number including any ordering suffixes that may indicate specific packaging or labeling variations. Confirm compatibility with the corresponding COMBI base terminal blocks before procurement. Ensure the required conductor cross-sections match the specified 0.25 mm² to 1.5 mm² range for proper termination. Check for any regional certification requirements such as UL or CE marking if applicable to your installation environment.

Selection Notes

Select this component when a single-pole, left-side plug is required for COMBI terminal systems. Ensure the application voltage does not exceed 500 V and the current load remains within the 17.5 A limit. Verify that the wire gauge falls within the supported range of 0.25 mm² to 1.5 mm². Consider the green-yellow color coding if earth or specific signal identification is necessary for the circuit design.

Part Context

This component belongs to the Phoenix Contact COMBI series, a standardized system of terminal blocks and accessories widely used in industrial automation. The series is characterized by its compact design, high current capacity, and compliance with international safety standards. These components are typically used in conjunction with spring-loaded or screw-type base terminals to create modular electrical connections.

Replacement Considerations

Direct substitutes must maintain the 5.2 mm pitch, single pole count, and 17.5 A rating. Compatible alternatives include other Phoenix Contact COMBI plugs with identical electrical specifications. Cross-brand replacements require verification of mechanical fit and insulation coordination parameters.
