2D25UM 25A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2D25UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 25A at 480V AC and 80V DC. This DIN rail-mounted device is part of the V-EA series and maintains active product status with full compliance to ROHS3, REACH, and international safety standards including CSA, UL508, and VDE certification. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the product line, enabling seamless integration in applications requiring identical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2D25UM are qualified based on strict parametric equivalence across all critical electrical and mechanical specifications. The following parameters must remain identical for substitution eligibility:

• Current Rating: 25A
• Voltage Rating (AC): 480V
• Voltage Rating (DC): 80V
• Breaker Type: Thermal Magnetic
• Mounting Type: DIN Rail
• Actuator Type: Lever
• Number of Poles: 2
• Series: V-EA
• Packaging: Bulk

All substitute parts (2B25UM, 2C25UM, 2G25UM) maintain these exact specifications, differing only in their characteristic designation (B, C, D, or G channel), which represents internal trip curve differentiation within the same product family. This differentiation does not affect mechanical or electrical compatibility in applications where the base electrical parameters are the controlling requirement.

Parameter Comparison

Engineering Selection Recommendations

All four parts (2D25UM, 2B25UM, 2C25UM, 2G25UM) maintain identical active product status and full compliance with ROHS3, REACH, CSA, UL508, and VDE standards. Selection between these parts should be based on application-specific trip curve requirements and inventory availability. The 2G25UM offers the highest current inventory level at 1135 pieces. All parts are packaged in bulk format and are suitable for direct substitution in DIN rail-mounted thermal magnetic circuit breaker applications requiring 25A, 480V AC, 80V DC specifications.

Frequently Asked Questions (FAQ)

Q: Can 2B25UM, 2C25UM, and 2G25UM be used interchangeably with 2D25UM?

A: Yes, these parts are parametric equivalents with identical electrical ratings (25A, 480V AC, 80V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), and mechanical specifications. The letter designation (B, C, D, G) indicates different trip curve characteristics within the V-EA series but does not affect mechanical or electrical compatibility for applications where base electrical parameters are specified.

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

A: The channel designation represents internal trip curve differentiation. All parts maintain the same current and voltage ratings and are mechanically compatible. Selection should be based on application-specific protection requirements and trip curve performance needs.

Q: Are all substitute parts ROHS3 and REACH compliant?

A: Yes, all four parts (2D25UM, 2B25UM, 2C25UM, 2G25UM) are ROHS3 compliant and REACH unaffected.

Q: Do all parts carry the same safety certifications?

A: The 2D25UM, 2B25UM, and 2C25UM carry CSA, UL508, and VDE certifications. The 2G25UM carries CSA and UL508 certifications. Verify certification requirements for your specific application before selection.

Q: What is the current inventory status for each part?

A: 2D25UM: 745 pieces; 2B25UM: 794 pieces; 2C25UM: 744 pieces; 2G25UM: 1135 pieces. All parts are new original stock in bulk packaging.
