2C2UM Thermal Magnetic Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The 2C2UM is a 2-ampere thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This DIN rail-mounted device is designed for 480 V AC and 80 V DC applications with lever actuation and dual-pole configuration. The product maintains active status with full compliance to CSA, UL508, and VDE standards. Substitute parts are identified based on identical electrical and mechanical parameters within the V-EA series, ensuring direct functional equivalence for component replacement and inventory optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2C2UM are identified as parametric equivalents within the Altech Corporation V-EA series. All substitute parts maintain identical specifications across the following critical parameters:

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

The substitute parts 2B2UM, 2D2UM, 2E2UM, and 2G2UM differ only in their base product designation (2B2, 2D2, 2E2, 2G2 respectively), which reflects internal Altech Corporation product line variants. All variants share identical electrical performance, mechanical form factor, and regulatory compliance profiles, making them functionally interchangeable for applications requiring 2-ampere thermal magnetic protection on DIN rail installations.

Parameter Comparison

Engineering Selection Recommendations

All five circuit breaker variants (2C2UM, 2B2UM, 2D2UM, 2E2UM, 2G2UM) maintain active product status and full compliance with CSA, UL508, and VDE regulatory standards. The 2C2UM carries VDE approval in addition to CSA and UL508 certifications. The 2B2UM, 2E2UM, and 2G2UM variants carry CSA and UL508 approvals, while 2D2UM carries CSA, UL508, and VDE approvals.

For applications requiring VDE compliance specifically, 2C2UM and 2D2UM are the appropriate selections. For applications where CSA and UL508 compliance is sufficient, all five variants are suitable. Component selection should be based on regulatory requirements of the target application and current inventory availability across the substitute options.

Frequently Asked Questions (FAQ)

Q: Can 2B2UM, 2D2UM, 2E2UM, or 2G2UM be used as direct replacements for 2C2UM?

A: Yes. All substitute parts share identical electrical ratings (2A, 480 V AC, 80 V DC), mechanical configuration (2-pole, lever-actuated, DIN rail mount), and thermal magnetic protection characteristics. They are functionally equivalent for circuit protection applications.

Q: Are there differences in regulatory compliance between the variants?

A: The 2C2UM and 2D2UM include VDE approval, while 2B2UM, 2E2UM, and 2G2UM carry CSA and UL508 approvals. Applications requiring VDE certification must use 2C2UM or 2D2UM. All variants meet CSA and UL508 standards.

Q: What distinguishes the base product numbers (2B2, 2C2, 2D2, 2E2, 2G2)?

A: The base product designations represent internal Altech Corporation product line variants. These designations do not affect electrical performance, mechanical compatibility, or functional operation. All variants within the V-EA series at 2-ampere rating are electrically and mechanically identical.

Q: Are all variants available in the same packaging format?

A: Yes. All substitute parts are supplied in bulk packaging, consistent with the 2C2UM primary part number.

Q: Can these circuit breakers be mixed in the same DIN rail installation?

A: Yes. All variants share identical DIN rail mounting specifications and form factors, allowing mixed deployment within a single installation where application requirements permit.
