Phoenix Contact 2794932 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2794932 is a 3-position feed-through terminal block connector rated for 10-26 AWG wire gauges with screw termination. Designed for applications requiring 30A current capacity at 110V UL rating, this component features integrated varistor protection and polyamide insulation with UL94 V-2 flammability rating. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new designs.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2794932 incorporates integrated varistor protection within a feed-through terminal block architecture. The substitute part 2906840 addresses the transient voltage suppression function through a dedicated module-based approach.

Substitution logic is based on the following critical parameters:

• Voltage protection capability: Main part provides 500V protection level through integrated varistor
• Operating voltage range: Main part rated 110V UL; substitute rated 150VAC/150VDC continuous operating voltage
• Circuit protection function: Both components provide transient voltage suppression
• Regulatory compliance: Both RoHS compliant with UL/CSA certifications
• Operating temperature range: Substitute rated -40°C to 85°C

The substitute represents a functional alternative for the protective element, though it operates as a separate module rather than an integrated terminal block assembly.

Parameter Comparison

Engineering Selection Recommendations

Selection between the main part and substitute must account for form factor and integration requirements:

The 2794932 provides an integrated terminal block with embedded varistor protection suitable for direct wire termination in compact assemblies. Its obsolete status requires replacement for new production or long-term availability assurance.

The 2906840 substitute provides equivalent voltage protection (500V level) with higher continuous operating voltage rating (150VAC/150VDC versus 110V) and active product status. However, this component functions as a separate module requiring DIN rail mounting rather than direct wire termination. Implementation requires architectural modification to accommodate module-based protection separate from terminal connection points.

Both components maintain equivalent RoHS compliance and regulatory certifications. The substitute's higher voltage rating and active status provide advantages for system longevity and regulatory continuity.

Frequently Asked Questions (FAQ)

Q: Can the 2906840 directly replace the 2794932 in existing assemblies?

A: Direct mechanical replacement is not possible. The 2794932 integrates terminal connection and protection in a single screw-terminal component, while the 2906840 is a separate DIN rail module. System redesign is required to accommodate the module-based architecture.

Q: What voltage protection level do both components provide?

A: Both components provide 500V protection level, meeting equivalent transient suppression requirements.

Q: Are both components RoHS compliant?

A: Yes. The 2794932 is RoHS Compliant; the 2906840 is ROHS3 Compliant, representing updated compliance standards.

Q: What is the operating temperature range for the 2794932?

A: Operating temperature range is not specified in the component documentation. The 2906840 substitute operates across -40°C to 85°C.

Q: Why is the 2794932 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 2906840 maintains active status, ensuring ongoing availability and support.

Q: What are the key differences in mounting approach?

A: The 2794932 uses screw termination for direct wire connection. The 2906840 uses DIN rail mounting for modular installation in control enclosures or distribution systems.
