1221469

Overview

The Phoenix Contact 1221469 is a six-position distribution block featuring Ex e certification for use in hazardous areas. It supports a rated voltage of 440 V during direct mounting and handles a rated current of 22.5 A with 2.5 mm² conductors, or up to 27 A with 4 mm² conductors. The unit exhibits a contact resistance of 0.6 mΩ. Designed for flexibility, it allows mounting via DIN rail adapters, direct flange attachment, or free-hanging installation. The housing is gray.

Feature Summary

• Ex e certified basic terminal block suitable for explosive atmospheres
• Versatile mounting options including DIN rail adapter, direct flange, and free-hanging configurations
• Internally bridged six-position design for efficient power distribution

Applications

• Installation in hazardous areas requiring Ex e protection
• Power distribution within control cabinets using DIN rail adapters
• Direct surface mounting applications utilizing the integrated flange
• Free-hanging cable management setups

Procurement Notes

Verify that the specific application environment meets Ex e certification requirements before deployment. Confirm conductor cross-section compatibility, as rated current varies between 22.5 A for 2.5 mm² and 27 A for 4 mm² wires. Ensure the chosen mounting method aligns with the mechanical constraints of the enclosure, whether using a DIN rail adapter, direct flange, or free-hanging setup. Check local regulations for hazardous area compliance.

Selection Notes

Select this component when Ex e certification is mandatory for the intended installation zone. Consider the required current capacity relative to the wire gauge; use 2.5 mm² for 22.5 A loads or 4 mm² for higher currents up to 27 A. Evaluate the physical installation space to determine if DIN rail, direct, or free-hanging mounting is feasible. The gray color coding may assist in visual identification within complex wiring schemes.
