2D05UM Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The 2D05UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, designed for DIN rail mounting applications. This two-pole device provides overcurrent protection at 500mA with dual voltage ratings of 480V AC and 80V DC. The product is currently active in production with full inventory availability (676 pcs in stock). Circuit breakers of this specification are essential components in industrial control panels and distribution systems where reliable thermal-magnetic protection is required across multiple voltage standards.

Key Parameters

Substitute Part Grouping Explanation

The 2E05UM qualifies as a parametric equivalent to the 2D05UM based on the following critical electrical and mechanical parameters:

Matching Parameters:

• Current Rating: 500mA (identical)
• Voltage Rating - AC: 480V (identical)
• Voltage Rating - DC: 80V (identical)
• Breaker Type: Thermal Magnetic (identical)
• Number of Poles: 2 (identical)
• Actuator Type: Lever (identical)
• Mounting Type: DIN Rail (identical)
• Series: V-EA (identical)
• RoHS Status: ROHS3 Compliant (identical)

Both parts are manufactured by Altech Corporation and maintain identical electrical performance characteristics and mechanical form factors. The substitution is valid where either part number can fulfill the same circuit protection function within the specified voltage and current parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 2D05UM and 2E05UM are active production components from Altech Corporation with full regulatory compliance. Selection between these parts should be based on:

Approval Requirements: The 2D05UM carries CSA, UL508, and VDE certifications, while the 2E05UM carries CSA and UL508 certifications. Applications requiring VDE compliance must specify the 2D05UM.

Inventory Availability: The 2E05UM has higher stock availability (1145 pcs) compared to the 2D05UM (676 pcs), which may influence procurement timelines for high-volume orders.

Electrical Performance: Both parts deliver identical electrical characteristics across all specified parameters and are interchangeable for applications not requiring VDE certification.

Frequently Asked Questions (FAQ)

Q: Can the 2E05UM replace the 2D05UM in all applications?

A: The 2E05UM is electrically and mechanically equivalent to the 2D05UM for all standard circuit protection functions. However, if your application or regional requirements mandate VDE certification, the 2D05UM must be used, as the 2E05UM does not carry this approval.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is valid when the following parameters match: current rating (500mA), AC voltage rating (480V), DC voltage rating (80V), breaker type (thermal magnetic), number of poles (2), actuator type (lever), and mounting type (DIN rail). Both parts meet these criteria.

Q: Are there any packaging differences between these parts?

A: Both the 2D05UM and 2E05UM are supplied in bulk packaging. No packaging format differences exist between these equivalent parts.

Q: Which part should I specify for new designs?

A: For new designs, either part is acceptable provided your application does not require VDE certification. Verify your regional compliance requirements and end-customer specifications before final selection.

Q: What is the difference between the base product numbers 2D05 and 2E05?

A: The base product numbers indicate different product lines within the Altech V-EA series. Both 2D05UM and 2E05UM are two-pole variants with identical electrical ratings and mechanical specifications, making them functionally equivalent despite different base designations.
