Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3048400 is determined by the following critical parameters:

• Number of Positions and Levels: Must be 2 positions, 1 level
• Terminal Width: Must be 18.0 mm
• Termination Style: Must be screw termination
• Disconnect Type: Must include fuse and lever functionality
• Fuse Type: Must accommodate 10.3 mm × 38 mm fuses
• Wire Gauge Compatibility: Must support minimum 4 AWG and accommodate the 1.5-25 mm² cross-section range
• Current and Voltage Ratings: Must meet or exceed IEC ratings of 32 A and 690 V, or equivalent UL ratings
• Flammability and Compliance: Must maintain UL94 V-0 rating and RoHS compliance

The Weidmüller 1966060000 qualifies as a substitute based on matching these core parameters, with the following considerations: it supports 4-18 AWG (broader upper range), maintains 32 A current capacity under IEC conditions, and achieves equivalent safety certifications.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1966060000 is a suitable substitute for the obsolete Phoenix Contact 3048400 based on the following factors:

Compliance and Certification: Both components maintain UL94 V-0 flammability ratings and RoHS compliance, ensuring equivalent safety and environmental standards.

Electrical Specifications: The Weidmüller part maintains the 32 A current capacity under IEC conditions and supports the same 1.5-25 mm² wire cross-section range. The extended wire gauge range (4-18 AWG versus 4-16 AWG) provides additional flexibility without compromising compatibility.

Mechanical Compatibility: Identical terminal width (18.0 mm), screw termination, and fuse/lever disconnect configuration ensure direct functional replacement in existing installations.

Product Availability: The Weidmüller 1966060000 is classified as active, providing reliable sourcing for ongoing component requirements.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1966060000 directly replace the Phoenix Contact 3048400 in existing applications?

A: Yes. Both components share identical terminal width (18.0 mm), screw termination, 2-position configuration, and 32 A current capacity under IEC conditions. The mechanical and electrical interfaces are compatible.

Q: What is the significance of the extended wire gauge range in the Weidmüller part (4-18 AWG versus 4-16 AWG)?

A: The Weidmüller 1966060000 accommodates wire gauges up to 18 AWG, compared to 16 AWG for the Phoenix Contact part. This broader range does not affect compatibility with the original 4-16 AWG specification and provides additional flexibility for future applications within the same 1.5-25 mm² cross-section envelope.

Q: Are there differences in insulation material between the two parts?

A: The Phoenix Contact 3048400 uses Polyamide (PA) and Nylon, while the Weidmüller 1966060000 uses Thermoplastic and Wemid. Both materials achieve the same UL94 V-0 flammability rating, ensuring equivalent electrical and thermal performance.

Q: What is the impact of the product status difference (Obsolete versus Active)?

A: The Phoenix Contact 3048400 is obsolete, making the Weidmüller 1966060000 the recommended alternative for new sourcing and system maintenance. The active status of the Weidmüller part ensures continued availability and supply chain reliability.

Q: Are the fuse specifications identical between the two parts?

A: Both components accommodate 10.3 mm × 38 mm fuses. The Phoenix Contact part specifies Class CC fuses, while the Weidmüller part does not specify a fuse class. Verify fuse compatibility with your application requirements and local electrical standards.

Q: Do both parts support the same voltage ratings?

A: The Phoenix Contact 3048400 is rated for 690 V (IEC). The Weidmüller 1966060000 is rated for 600 V (UL). For applications requiring 690 V operation, verify that the Weidmüller part meets your specific voltage requirements before implementation.
