Altech Corporation 2D8UM Circuit Breaker Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2D8UM is a thermal magnetic circuit breaker rated for 8A at 480V AC and 80V DC, configured as a 2-pole DIN rail mounted device with lever actuation. This component is Active in product status and carries UL508, CSA, and VDE approvals. Substitute parts are identified when equivalent electrical ratings, mechanical mounting, and approval certifications align with the main part specifications, enabling direct replacement in applications requiring identical performance parameters.

Substitute Part Grouping Explanation

Substitute parts for the 2D8UM are qualified based on the following electrical and mechanical parameters:

• Current Rating: 8A (exact match required)
• Voltage Rating - AC: 480V (exact match required)
• Voltage Rating - DC: 80V (exact match required)
• Number of Poles: 2 (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)
• Series: V-EA (exact match required)
• Approval Agencies: CSA and UL508 minimum (VDE approval optional)

The substitute parts 2C8UM, 2G8UM, and 2Z8UM meet all mandatory electrical and mechanical parameters. These parts differ only in their thermal-magnetic trip characteristics (C, G, and Z designations respectively), which represent different response curves for specific load protection requirements. All substitute parts maintain Active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and carry minimum CSA and UL508 approvals required for industrial circuit protection applications. The 2C8UM and 2G8UM provide additional VDE certification, extending compliance scope for European market applications. Selection between 2D8UM, 2C8UM, 2G8UM, and 2Z8UM is determined by the specific thermal-magnetic trip curve required for the protected circuit. All parts are ROHS3 compliant and available in bulk packaging with current inventory levels supporting immediate deployment.

Frequently Asked Questions (FAQ)

Q: Can 2C8UM, 2G8UM, or 2Z8UM be used as direct replacements for 2D8UM?

A: Yes. All substitute parts share identical electrical ratings (8A, 480V AC, 80V DC), mechanical configuration (2-pole, DIN rail, lever actuation), and series designation (V-EA). Selection depends on the required trip characteristic curve for the application.

Q: What is the difference between the D, C, G, and Z designations?

A: These letters indicate different thermal-magnetic trip characteristics. The specific curve determines the breaker response time and current threshold at which the magnetic trip activates. Application requirements dictate which characteristic is appropriate.

Q: Are all substitute parts approved for the same regulatory standards?

A: All parts carry CSA and UL508 approvals. The 2C8UM and 2G8UM additionally carry VDE certification. The 2D8UM and 2Z8UM carry CSA and UL508 only. Regulatory requirements for your application determine which approvals are necessary.

Q: Is there a difference in physical dimensions or DIN rail compatibility?

A: No. All parts are configured for identical DIN rail mounting with lever actuation. Physical form factor and mounting footprint are equivalent across all substitute parts.

Q: What inventory levels are available for each part?

A: Current inventory includes 2D8UM (864 pcs), 2C8UM (666 pcs), 2G8UM (769 pcs), and 2Z8UM (680 pcs), all new original stock in bulk packaging.
