Equivalent & Substitute Parts for 2C3UM Circuit Breaker

Part Overview

The 2C3UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This 2-pole DIN rail-mounted breaker is rated for 3A at 480V AC and 80V DC with lever actuation. The product is active and widely stocked (748 units in inventory). Circuit breakers of this specification are essential components in electrical distribution systems, and equivalent alternatives may be required due to supply chain considerations, inventory availability, or system standardization needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2C3UM is determined by strict equivalence across the following critical parameters:

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

All three substitute parts (2D3UM, 2G3UM, 2Z3UM) meet these electrical and mechanical specifications. Substitution is valid when these parameters remain constant across the main part and substitute part.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (2D3UM, 2G3UM, 2Z3UM) are functionally equivalent to the 2C3UM based on electrical and mechanical parameters. Selection among these alternatives should be based on the following factors:

Certification Alignment: The 2C3UM and 2D3UM both carry CSA, UL508, and VDE approvals. The 2G3UM and 2Z3UM carry CSA and UL508 approvals. If VDE certification is a system requirement, 2C3UM or 2D3UM must be selected.

Inventory Availability: The 2D3UM has the highest stock level (1007 units), followed by 2G3UM (835 units), 2Z3UM (814 units), and 2C3UM (748 units). Selection may be influenced by procurement lead time requirements.

Product Status: All parts maintain active product status, ensuring continued manufacturer support and availability.

Regulatory Compliance: All substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, meeting current environmental and export control requirements.

Frequently Asked Questions (FAQ)

Q: Can 2D3UM, 2G3UM, or 2Z3UM be used as direct replacements for 2C3UM?

A: Yes. All three parts are parametric equivalents with identical electrical ratings (3A, 480V AC, 80V DC), mechanical configuration (2-pole, DIN rail, lever actuation), and thermal magnetic operation. Direct substitution is valid from an electrical and mechanical standpoint.

Q: Are there differences in certification between the substitute parts?

A: Yes. The 2C3UM and 2D3UM carry CSA, UL508, and VDE approvals. The 2G3UM and 2Z3UM carry CSA and UL508 approvals only. If your application requires VDE certification, use 2C3UM or 2D3UM.

Q: Do all parts meet the same environmental and regulatory standards?

A: Yes. All four parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All share the same HTSUS code (8536.20.0020).

Q: Which substitute part should I select based on availability?

A: The 2D3UM offers the highest inventory level (1007 units). If procurement speed is critical, 2D3UM is the preferred choice. All parts are currently in stock.

Q: Are there any packaging differences between these parts?

A: No. All four parts are supplied in bulk packaging with no illumination features.

Q: Can these parts be used interchangeably in existing installations?

A: Yes, provided that the installation does not have specific certification requirements beyond CSA and UL508. If VDE certification is mandated, only 2C3UM or 2D3UM are suitable.
