Altech Corporation 2E3UM Thermal Magnetic Circuit Breaker Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2E3UM is a thermal magnetic circuit breaker rated for 3A at 480V AC and 80V DC, designed for DIN rail mounting with lever actuation and two poles. This component is active in production and widely used in industrial control and distribution applications. Substitute parts become necessary when the primary part number is unavailable, when inventory constraints require alternative sourcing, or when system design modifications necessitate compatible alternatives within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts listed for the 2E3UM maintain identical electrical and mechanical parameters that define interchangeability within the V-EA series. Substitution is based strictly on the following criteria:

Critical Parameters for Substitution:

• Current Rating: 3A (all substitutes)
• Voltage Rating - AC: 480V (all substitutes)
• Voltage Rating - DC: 80V (all substitutes)
• Breaker Type: Thermal Magnetic (all substitutes)
• Mounting Type: DIN Rail (all substitutes)
• Actuator Type: Lever (all substitutes)
• Number of Poles: 2 (all substitutes)
• Series: V-EA (all substitutes)
• Packaging: Bulk (all substitutes)

The substitute parts 2C3UM, 2D3UM, 2G3UM, and 2Z3UM are parametric equivalents that differ only in their character designation (C, D, G, Z) within the base product number structure. These designations reflect internal Altech Corporation product line variations that do not affect electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are active production components with identical electrical ratings and mechanical specifications. Selection among 2E3UM, 2C3UM, 2D3UM, 2G3UM, and 2Z3UM is based on availability and inventory status rather than technical differentiation.

Approval Agency Considerations:

The 2E3UM and 2G3UM carry CSA and UL508 certifications. The 2C3UM and 2D3UM carry CSA, UL508, and VDE certifications, providing additional compliance coverage for applications requiring European standards alignment. All parts maintain ROHS3 compliance and REACH unaffected status, suitable for environmentally regulated applications.

Current inventory levels are: 2D3UM (1007 pcs), 2G3UM (835 pcs), 2Z3UM (814 pcs), 2C3UM (748 pcs), and 2E3UM (704 pcs). Selection may prioritize parts with higher stock availability for supply chain optimization.

Frequently Asked Questions (FAQ)

Q: Can 2C3UM, 2D3UM, 2G3UM, and 2Z3UM be used interchangeably with 2E3UM?

A: Yes. All parts share identical electrical ratings (3A, 480V AC, 80V DC), breaker type (thermal magnetic), mounting configuration (DIN rail, 2-pole lever actuation), and series designation (V-EA). They are parametric equivalents within the Altech Corporation product line.

Q: What is the difference between the character designations (E, C, D, G, Z) in the part numbers?

A: The character designation is an internal Altech Corporation product line identifier that does not affect electrical performance, mechanical compatibility, or physical dimensions. All designated variants maintain identical specifications for the 3A thermal magnetic circuit breaker.

Q: Are there differences in approval certifications among these parts?

A: The 2E3UM and 2G3UM carry CSA and UL508 approvals. The 2C3UM and 2D3UM carry CSA, UL508, and VDE approvals. The 2Z3UM carries CSA and UL508 approvals. Selection should consider whether VDE certification is required for the application.

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

A: Yes. Since all parts are parametric equivalents with identical electrical and mechanical specifications, they can be used together in multi-breaker installations without compatibility issues.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed substitute parts (2C3UM, 2D3UM, 2G3UM, 2Z3UM) and the main part (2E3UM) are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.

Q: Which part should be selected if VDE certification is required?

A: The 2C3UM or 2D3UM should be selected, as both carry VDE certification in addition to CSA and UL508 approvals.
