Phoenix Contact 3009121 Terminal Block Ground Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3009121 is a CLIPLINE UKH series terminal block ground connector rated for 1/0-6 AWG wire gauges (16-70mm²). This 2-position ground/earth connector features screw termination and is rated for 150A at 1000V (IEC) or 600V (UL). The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3009121 is determined by the following critical electrical and mechanical parameters:

• Wire Gauge Compatibility: Substitute parts must accommodate 1/0-6 AWG (16-70mm²) wire gauges
• Current Rating: Minimum 150A capacity required
• Termination Method: Screw termination required for mechanical compatibility
• Position Configuration: 2-position, single-level layout
• Terminal Width: 20.0mm standard
• Insulation Material: Polyamide (PA) or equivalent nylon-based material with UL94 V-0 flammability rating
• Connector Type: Ground/earth terminal block designation
• Stripping Length: 24mm wire preparation requirement

The Phoenix Contact 0443049 qualifies as a direct substitute based on matching all critical parameters within the allowed electrical and mechanical specifications for this product category.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 0443049 is the qualified substitute for the obsolete 3009121. Both components share identical electrical ratings (150A, 1000V IEC), mechanical configuration (2-position, 20.0mm terminal width), and wire gauge specifications (1/0-6 AWG / 16-70mm²). Both components maintain RoHS compliance and UL94 V-0 flammability certification.

The primary distinction is product status: the 3009121 is obsolete while the 0443049 is active. The 0443049 operates within the CLIPLINE USLKG series and is available in bulk packaging, ensuring supply continuity for new installations and system replacements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 0443049 directly replace the 3009121 in existing installations?

A: Yes. Both components share identical electrical ratings (150A at 1000V IEC), mechanical dimensions (20.0mm terminal width, 2-position configuration), wire gauge compatibility (1/0-6 AWG), and termination method (screw). The 0443049 is the active production equivalent.

Q: What are the key compatibility criteria for substituting the 3009121?

A: Substitute components must maintain: 150A minimum current rating, 1000V IEC voltage rating, 1/0-6 AWG wire gauge accommodation, 20.0mm terminal width, 2-position single-level layout, screw termination, and UL94 V-0 insulation material specification.

Q: Does the series change from CLIPLINE UKH to CLIPLINE USLKG affect compatibility?

A: No. Series designation reflects product line evolution within Phoenix Contact's terminal block portfolio. The electrical and mechanical parameters that determine functional compatibility remain identical between the two series.

Q: Are there packaging differences between the 3009121 and 0443049?

A: The 3009121 was supplied with standard packaging (status not specified), while the 0443049 is available in bulk packaging. Both components are RoHS compliant and suitable for the same electrical applications.

Q: What compliance certifications apply to both components?

A: Both the 3009121 and 0443049 are RoHS compliant, feature UL94 V-0 flammability-rated insulation material, and carry ECCN EAR99 classification with HTSUS code 8536.69.8000.
