Altech Corporation 2E8UM 8A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2E8UM is an active thermal magnetic circuit breaker manufactured by Altech Corporation, designed for DIN rail mounting applications. This 8-ampere, 2-pole breaker operates at 480 V AC and 80 V DC with lever actuation and meets CSA and UL508 approval standards. Substitute parts within the V-EA series maintain identical electrical and mechanical specifications, enabling direct replacement in applications where component availability or inventory requirements necessitate alternative part selection.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts listed—2C8UM, 2D8UM, 2G8UM, and 2Z8UM—are qualified equivalents based on the following criteria:

Electrical Parameters: Current rating (8A), AC voltage rating (480 V), and DC voltage rating (80 V) are identical across all parts.

Mechanical Parameters: All parts feature 2-pole configuration, lever actuation, DIN rail mounting, and thermal magnetic breaker type.

Regulatory Compliance: All parts maintain ROHS3 compliance and active product status. Substitute parts 2C8UM and 2D8UM include additional VDE approval beyond the base CSA and UL508 certifications.

Series Designation: All parts belong to the V-EA series, confirming compatibility within the product family.

The primary distinction among these parts is the thermal characteristic designation (E, C, G, Z), which defines the trip curve behavior but does not affect the fundamental electrical or mechanical substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

All five part numbers are active products with ROHS3 compliance and meet the specified electrical and mechanical requirements for direct substitution. Selection among 2E8UM, 2C8UM, 2D8UM, 2G8UM, and 2Z8UM should be based on application-specific thermal characteristic requirements and regulatory jurisdiction. Parts 2C8UM and 2D8UM provide extended approval coverage through VDE certification, suitable for applications requiring European standards compliance. Current inventory levels range from 666 to 991 units across all part numbers, supporting procurement flexibility.

Frequently Asked Questions (FAQ)

Q: Can 2C8UM, 2D8UM, 2G8UM, or 2Z8UM be used as direct replacements for 2E8UM?

A: Yes. All substitute parts maintain identical current rating (8A), voltage ratings (480 V AC, 80 V DC), pole configuration (2-pole), mounting type (DIN rail), and actuator type (lever). They are electrically and mechanically interchangeable within the V-EA series.

Q: What is the difference between the thermal characteristic designations (E, C, G, Z)?

A: The letter designation indicates the trip curve characteristic of the breaker, which defines the thermal response behavior. This parameter is provided in the input data but does not affect electrical or mechanical substitution compatibility.

Q: Are there differences in regulatory approvals among these parts?

A: Parts 2E8UM, 2G8UM, and 2Z8UM carry CSA and UL508 approvals. Parts 2C8UM and 2D8UM include additional VDE approval. All parts are ROHS3 compliant and active products.

Q: Can these parts be mixed in the same installation?

A: Yes, provided the application design accommodates the specific thermal characteristics of each part number. All parts share identical electrical ratings and mechanical form factors.

Q: What packaging is available for these parts?

A: All parts are supplied in bulk packaging as specified by Altech Corporation.
