Altech Corporation 2Z5UM 5A Circuit Breaker Z Char2 - Equivalent & Substitute Parts

Part Overview

The 2Z5UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This DIN rail-mounted breaker is rated for 5A at 480V AC and 80V DC with lever actuation and dual-pole configuration. The product is active and ROHS3 compliant with CSA and UL508 approvals. Equivalent substitute parts are available within the same series when the Z characteristic curve is not a specific requirement or when alternative trip characteristics better suit application needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2Z5UM is determined by equivalence across the following critical parameters:

• Current Rating: 5A (all substitutes match)
• Voltage Rating - AC: 480V (all substitutes match)
• Voltage Rating - DC: 80V (all substitutes match)
• Breaker Type: Thermal Magnetic (all substitutes match)
• Mounting Type: DIN Rail (all substitutes match)
• Actuator Type: Lever (all substitutes match)
• Number of Poles: 2 (all substitutes match)
• Series: V-EA (all substitutes match)
• Packaging: Bulk (all substitutes match)

The substitute parts 2B5UM, 2C5UM, 2D5UM, 2E5UM, and 2G5UM differ only in their trip characteristic designation (B, C, D, E, and G respectively), which is reflected in the part number suffix. All other electrical and mechanical parameters remain identical to the 2Z5UM.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain identical electrical and mechanical specifications to the 2Z5UM. Selection among these equivalents is based on the following factors:

Certification Coverage: Parts 2C5UM and 2D5UM carry additional VDE approval beyond CSA and UL508. These are suitable for applications requiring European compliance standards.

Product Availability: All parts are active products with current inventory. The 2B5UM offers the highest inventory level at 1102 pieces, followed by 2G5UM at 1039 pieces and 2E5UM at 1033 pieces.

Compliance Status: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 2Z5UM with any of the listed equivalent parts?

A: Yes. The 2B5UM, 2C5UM, 2D5UM, 2E5UM, and 2G5UM are parametric equivalents with identical current rating, voltage ratings, mounting type, actuator type, pole configuration, and breaker technology. The only difference is the trip characteristic curve designation.

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

A: These designations indicate different trip characteristic curves for the thermal magnetic breaker. The provided data does not specify the technical differences between these curves; selection should be based on application-specific trip requirements.

Q: Are all substitute parts certified to the same standards?

A: The 2Z5UM, 2B5UM, 2E5UM, and 2G5UM carry CSA and UL508 approvals. The 2C5UM and 2D5UM carry CSA, UL508, and VDE approvals. All parts meet ROHS3 compliance requirements.

Q: What is the packaging format for these parts?

A: All parts are supplied in bulk packaging.

Q: Are there any inventory considerations for selection?

A: Current inventory levels vary. The 2B5UM has the highest stock at 1102 pieces, while the 2D5UM has the lowest at 850 pieces. All parts are listed as active products.
