1596782

Overview

The Phoenix Contact part number 1596782 corresponds to the FKC 2,5/ 3-STF-5,08 EX, a PCB connector from the COMBICON Connectors M product line. This component features a nominal cross-section of 2.5 mm² and a pitch of 5.08 mm. It utilizes push-in spring connection technology for conductor attachment and includes a screw locking mechanism with a mounting method of screw flange. The connector is designed for three potentials across one row, providing three positions and connections. It has a nominal current rating of 12 A and a nominal voltage of 176 V. The unit is packaged in cardboard and exhibits a green color with tin contact surfaces.

Feature Summary

• Equipped with Ex approval for use in hazardous areas, certified under EU-type examination certificate KEMA 10ATEX0196 U and IECEx certificate IECEx KEM 10.0093U.
• Utilizes push-in spring connection technology that allows for tool-free assembly and secure conductor attachment.
• Features a screw locking mechanism combined with a screw flange mounting method to ensure superior mechanical stability.

Applications

• Installation in control cabinets requiring narrow circuit breakers or compact connectors to save space.
• Automation systems operating in potentially explosive atmospheres (Zone 1, 2, 21, 22) where Ex eb IIC Gb protection is required.
• Industrial process heating applications satisfying standards such as DIN EN ISO 13577-2/4 and NFPA 85, 86, 87.

Procurement Notes

Verify the specific Ex approval codes (KEMA 10ATEX0196 U and IECEx KEM 10.0093U) against your site's hazardous area classification before procurement. Confirm that the 12 A nominal current and 176 V nominal voltage align with your system's electrical requirements. Ensure the 5.08 mm pitch matches your PCB layout design. Check for compatibility with mating parts within the COMBICON MSTB 2,5 EX plug-in system.

Selection Notes

Select this component when an explosion-proof PCB connector is necessary for industrial environments. The push-in spring connection offers a reliable alternative to screw terminals, reducing assembly time. The screw flange provides enhanced mechanical stability compared to standard snap-in mounts. Consider the green color coding if it aligns with your facility's visual identification standards for Ex components.
