Phoenix Contact 3048072 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3048072 is a 2-position feed-through terminal block connector from the CLIPLINE UK series, designed for wire gauges 1/0-18 AWG (0.75-50 mm²). This component operates at 150 A (IEC) and 1000 V (IEC), with screw termination and polyamide insulation rated UL94 V-0. The part is currently in Last Time Buy status, indicating discontinued production. Identifying equivalent substitute parts is necessary to ensure continued availability and maintain system compatibility for new installations and replacements.

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3048072 is based on the following critical parameters that must remain compatible:

Connector Type & Configuration: 2-position, 1-level, feed-through terminal block with screw termination
Electrical Ratings: Minimum 1000 V voltage rating; current rating of 125 A or higher
Wire Gauge Compatibility: Support for wire sizes within the 1/0-18 AWG range (0.75-50 mm²)
Physical Compatibility: Terminal width and stripping length suitable for the application
Material & Certification: Polyamide insulation with UL94 V-0 flammability rating
Color Coding: Blue insulation for consistent identification

The Phoenix Contact 3047730 (CLIPLINE UT series) qualifies as a substitute based on these parameters. While it operates at 125 A (IEC) and supports a slightly narrower wire gauge range (1/0-14 AWG), it maintains the required 1000 V rating, 2-position configuration, screw termination, and UL94 V-0 certification. The 3047730 also supports the full 0.75-50 mm² range in metric specification.

Engineering Selection Recommendations

The Phoenix Contact 3047730 is an active production substitute for the discontinued 3048072. Both components meet the same voltage specification (1000 V) and insulation flammability standard (UL94 V-0). The 3047730 maintains the required 2-position, feed-through configuration with screw termination and polyamide insulation.

The primary difference is the current rating: the 3047730 is rated 125 A under IEC conditions, compared to 150 A for the 3048072. For applications requiring the full 150 A capacity, the UL rating of the 3047730 (150 A) may provide equivalent performance under UL-governed installations. The wire gauge range of the 3047730 (1/0-14 AWG) is narrower than the original part, excluding the 16 AWG and 18 AWG sizes; however, the metric specification (1.5-50 mm²) covers the majority of industrial applications.

The 3047730 is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 3047730 directly replace the 3048072 in all applications?

A: The 3047730 is suitable for applications operating at or below 125 A (IEC) or 150 A (UL). If your application requires the full 150 A IEC rating, verify that UL-rated operation is acceptable for your system. Both parts support 1000 V operation and identical 2-position, feed-through configurations.

Q: What is the difference in wire gauge compatibility?

A: The 3048072 supports 1/0-18 AWG; the 3047730 supports 1/0-14 AWG. If your installation uses 16 AWG or 18 AWG conductors, the 3047730 cannot accommodate these sizes. For 1/0-14 AWG applications, both parts are compatible.

Q: Are the physical dimensions interchangeable?

A: The terminal width differs slightly (15.1 mm vs. 16.0 mm) and stripping length differs (16 mm vs. 18 mm). Verify that your mounting and termination procedures accommodate these dimensional variations before installation.

Q: Why is the 3048072 in Last Time Buy status?

A: Last Time Buy status indicates Phoenix Contact has discontinued this product line. The 3047730 from the CLIPLINE UT series represents the current production equivalent, ensuring ongoing availability and support.

Q: Do both parts meet the same safety certifications?

A: Yes. Both the 3048072 and 3047730 are UL94 V-0 rated and RoHS compliant, meeting equivalent safety and environmental standards.
