Phoenix Contact 3059249 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3059249 is a 12-position NEMA open construction terminal block from the CLIPLINE RSC series, designed for DIN rail mounting with screw termination. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and new designs requiring compatible components.

The primary reason for sourcing substitute parts is the obsolete status of the 3059249. Active production alternatives with equivalent electrical and mechanical specifications ensure continued availability and supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3059249 is based on the following critical parameters that must remain equivalent:

Electrical Compatibility:

Current rating: 57 A (IEC) / 45 A (UL)
Voltage rating: 800 V (IEC) / 600 V (UL)
Wire gauge acceptance: 8-26 AWG (0.1-6 mm²)

Mechanical Compatibility:

12-position configuration
Single-level design
NEMA open construction type
Gray housing color
Polyamide (PA) nylon insulation with UL94 V-0 rating

Regulatory Compliance:

RoHS compliant status
UL and IEC certification alignment

The substitute part 3059252 maintains electrical ratings, position count, housing material, and regulatory compliance. Differences in mounting type (DIN rail vs. direct mount) and termination style (screw vs. bolt and nut) represent functional variations that do not prevent substitution when system design accommodates these mechanical changes.

Engineering Selection Recommendations

The Phoenix Contact 3059252 is the manufacturer-recommended substitute for the obsolete 3059249. Both components maintain identical electrical performance across IEC and UL standards, with equivalent current and voltage ratings suitable for industrial control applications.

The 3059252 offers expanded wire gauge acceptance (0.1-10 mm² versus 0.1-6 mm²), providing greater flexibility for conductor sizing. The transition from screw termination to bolt-and-nut termination and from DIN rail to direct mount represents a mechanical interface change that requires system-level evaluation. These differences do not affect electrical compatibility or performance characteristics.

Both parts maintain RoHS compliance and UL94 V-0 flammability certification, ensuring regulatory alignment for industrial and commercial installations. The active production status of the 3059252 guarantees long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 3059252 directly replace the 3059249 in existing installations?

A: Electrical substitution is valid. The 3059252 maintains identical current and voltage ratings. Physical installation requires evaluation of mounting method (DIN rail vs. direct mount) and termination interface (screw vs. bolt-and-nut) compatibility with existing system design.

Q: What is the significance of the wire gauge range difference?

A: The 3059252 accepts wire gauges from 0.1-10 mm², compared to 0.1-6 mm² for the 3059249. This expanded range provides additional conductor sizing options without affecting compatibility with the original specification range.

Q: Are both parts certified to the same standards?

A: Yes. Both the 3059249 and 3059252 carry UL94 V-0 flammability certification and RoHS compliance. Electrical ratings conform to both IEC and UL standards with identical specifications.

Q: Why is the 3059249 classified as obsolete?

A: The 3059249 has been discontinued by Phoenix Contact. The 3059252 from the CLIPLINE RBO series represents the active production alternative with equivalent electrical specifications.

Q: What is the difference between DIN rail and direct mount configurations?

A: DIN rail mounting (3059249) uses standardized rail attachment for modular installation. Direct mount (3059252) requires fixed mechanical fastening to a panel or enclosure. Selection depends on system architecture and installation requirements.

Q: Does the bolt-and-nut termination affect electrical performance?

A: No. Bolt-and-nut termination provides equivalent electrical connection to screw termination. The choice between termination styles depends on installation methodology and maintenance procedures specific to the application.
