2C25UM 25A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2C25UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This DIN rail-mounted breaker is designed for 25A applications at 480V AC and 80V DC with lever actuation and dual-pole configuration. The product is currently active and widely available in inventory. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and regulatory certifications to support procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2C25UM are identified as parametric equivalents within the Altech V-EA series. All substitute parts share identical electrical and mechanical specifications:

• Current Rating: 25A
• Voltage Rating: 480V AC / 80V DC
• Breaker Type: Thermal Magnetic
• Mounting: DIN Rail
• Poles: 2
• Actuator: Lever
• Series: V-EA
• RoHS Compliance: ROHS3

The primary distinction among these parts is the internal characteristic designation (B, C, D, G), which defines the trip curve behavior. All variants maintain the same form factor, electrical ratings, and regulatory certifications (CSA, UL508, VDE), making them mechanically and electrically interchangeable within applications where the specific trip curve is not a critical design parameter.

Parameter Comparison

Engineering Selection Recommendations

All four circuit breaker models (2C25UM, 2B25UM, 2D25UM, 2G25UM) are active products with full regulatory compliance. Selection among these equivalents should be based on:

1. Trip curve requirements: The characteristic designation (B, C, D, G) determines the thermal-magnetic trip curve. Verify application requirements against the specific curve needed.

2. Regulatory certification scope: The 2C25UM, 2B25UM, and 2D25UM carry CSA, UL508, and VDE certifications. The 2G25UM carries CSA and UL508 certifications. Confirm that the selected part meets all required certifications for the target application and jurisdiction.

3. Inventory availability: All parts are in active stock. The 2G25UM offers the highest inventory level (1135 pcs), while 2C25UM, 2B25UM, and 2D25UM maintain comparable availability (744–794 pcs).

Frequently Asked Questions (FAQ)

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

A: These parts are mechanically and electrically interchangeable in terms of form factor, current rating, voltage rating, and mounting configuration. However, the characteristic designation (B, C, D, G) defines the trip curve behavior. Substitution is valid only if the application does not require a specific trip curve characteristic.

Q: What is the difference between the characteristic designations (B, C, D, G)?

A: The characteristic designation defines the thermal-magnetic trip curve, which determines the current threshold and response time for fault conditions. Selection must align with application requirements and system coordination needs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all four models (2C25UM, 2B25UM, 2D25UM, 2G25UM) are ROHS3 compliant.

Q: Do all substitute parts carry the same regulatory certifications?

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

Q: Are these parts available in different packaging options?

A: All four models are supplied in bulk packaging as specified in the provided data.

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

A: 2C25UM: 744 pcs; 2B25UM: 794 pcs; 2D25UM: 745 pcs; 2G25UM: 1135 pcs. All are listed as new original stock.
