2D2.5UM Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The 2D2.5UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This DIN rail-mounted breaker is rated for 2.5A at 480V AC and 80V DC, featuring a lever actuator and two poles. The product is active and in stock with 902 units available. Circuit breakers of this specification are essential components in electrical distribution systems where overcurrent protection and thermal-magnetic trip characteristics are required for equipment safety and system reliability.

Substitute Part Grouping Explanation

The 2D2.5UM has two parametric equivalents within the Altech V-EA series: 2E2.5UM and 2G2.5UM. Substitution eligibility is determined by the following critical parameters that remain constant across all three parts:

• Current Rating: 2.5A
• Voltage Rating - AC: 480V
• Voltage Rating - DC: 80V
• Breaker Type: Thermal Magnetic
• Mounting Type: DIN Rail
• Number of Poles: 2
• Actuator Type: Lever
• Series: V-EA
• Packaging: Bulk

The differences between these parts are limited to the base product designation (2D, 2E, 2G) and approval agency certifications. The 2D2.5UM carries CSA, UL508, and VDE approvals, while 2E2.5UM and 2G2.5UM carry CSA and UL508 approvals. All three parts maintain identical electrical and mechanical specifications, making them interchangeable for applications requiring the specified current and voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2D2.5UM, 2E2.5UM, and 2G2.5UM—are active products with ROHS3 compliance and CSA/UL508 certifications. Selection between these equivalents should be based on regulatory requirements specific to the application:

• 2D2.5UM: Select when VDE certification is required in addition to CSA and UL508 approvals.
• 2E2.5UM or 2G2.5UM: Select when CSA and UL508 certifications are sufficient for the application.

All three parts are suitable for 2.5A thermal magnetic protection in 480V AC / 80V DC systems with DIN rail mounting. Inventory availability should be considered as a secondary factor, with 2G2.5UM offering the highest stock level at 1133 units.

Frequently Asked Questions (FAQ)

Q: Can 2E2.5UM or 2G2.5UM be used as direct replacements for 2D2.5UM?

A: Yes, provided that VDE certification is not a mandatory requirement for your application. All three parts share identical electrical ratings (2.5A, 480V AC, 80V DC), breaker type (thermal magnetic), mounting configuration (DIN rail, 2-pole), and actuator type (lever). The primary difference is certification scope.

Q: What is the difference between 2D2.5UM, 2E2.5UM, and 2G2.5UM?

A: The base product designations (2D, 2E, 2G) distinguish certification profiles. The 2D2.5UM includes VDE approval, while 2E2.5UM and 2G2.5UM do not. All other electrical and mechanical parameters are identical.

Q: Are these parts interchangeable in terms of physical dimensions and DIN rail mounting?

A: Yes. All three parts are DIN rail-mounted with identical mounting specifications and are mechanically interchangeable.

Q: Which part should I select if I need the fastest delivery?

A: Inventory levels are 902 units (2D2.5UM), 1060 units (2E2.5UM), and 1133 units (2G2.5UM). Selection should prioritize your certification requirements first, then consider inventory availability.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and carry identical environmental compliance status.
