Weidmüller 1024550000 Terminal Block Connector - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1024550000 is a 2-position feed-through terminal block connector rated for 250MCM (kcmil) to 2 AWG wire gauges. This component is designed for high-current applications requiring screw termination with robust insulation properties. The part is currently active in production and maintains full inventory availability. Alternative equivalent parts may be required due to color specification constraints, voltage rating differences, or regional compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

The Weidmüller 1024500000 qualifies as a direct equivalent substitute based on the following matching parameters:

• Identical manufacturer (Weidmüller)
• Identical series (W)
• Identical type (Feed Through)
• Identical number of positions (2) and levels (1)
• Identical wire gauge range (250MCM to 2 AWG / 35-150mm²)
• Identical terminal width (32.0mm)
• Identical termination style (Screw)
• Identical insulation material (Thermoplastic, Wemid)
• Identical flammability rating (UL94 V-0)
• Identical stripping length (35mm)
• Identical IEC current rating (309 A) and voltage rating (1000V)
• Identical UL current rating (225 A)

The primary differences are color specification (Beige vs. Green) and UL voltage rating (600V vs. 1000V). These differences do not affect functional interchangeability in applications where the lower voltage rating is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products with full production status and identical core electrical and mechanical specifications. The 1024550000 maintains a UL voltage rating of 1000V, while the 1024500000 is rated at 600V under UL standards. Selection between these parts depends on the application voltage requirement. For systems operating at voltages exceeding 600V, the 1024550000 is the appropriate choice. For applications at or below 600V, either part is functionally equivalent. Both parts carry UL94 V-0 flammability certification and are REACH Unaffected, meeting standard compliance requirements for industrial terminal block applications.

Frequently Asked Questions (FAQ)

Q: Can the 1024500000 be used in place of the 1024550000?

A: The 1024500000 is functionally equivalent for applications operating at 600V or below. The primary difference is the UL voltage rating: 1024550000 is rated 1000V, while 1024500000 is rated 600V. If your application requires 1000V rating, use the 1024550000.

Q: What is the significance of the color difference between these parts?

A: The color difference (Green vs. Beige) is a visual identifier only and does not affect electrical or mechanical performance. Color selection is typically based on installation standards or organizational coding practices.

Q: Are both parts compatible with the same wire gauge specifications?

A: Yes. Both parts accept wire gauges from 250MCM (kcmil) to 2 AWG, equivalent to 35-150mm². Terminal width, stripping length, and screw termination are identical.

Q: What is the current-carrying capacity of these terminal blocks?

A: Under IEC standards, both parts are rated for 309 A. Under UL standards, both are rated for 225 A. Use the applicable standard rating for your regional requirements.

Q: Are these parts RoHS compliant?

A: The 1024500000 is explicitly RoHS Compliant. The 1024550000 does not specify RoHS status in the provided data. Verify RoHS compliance requirements with your supplier if this is a critical specification for your application.

Q: What insulation material is used in these terminal blocks?

A: Both parts use Thermoplastic Wemid insulation with UL94 V-0 flammability rating, providing robust fire resistance suitable for industrial applications.
