2E2.5UM Thermal Magnetic Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The 2E2.5UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 2.5A at 480V AC and 80V DC. This DIN Rail-mounted breaker features a lever actuator and dual-pole configuration, designed for industrial control and distribution applications. The part is currently active in production with 1,060 units in stock. Equivalent substitute parts are available within the V-EA series to accommodate supply chain requirements, regional certification needs, or specific application preferences while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The 2E2.5UM has two parametric equivalents within the V-EA series: 2D2.5UM 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
• RoHS Status: ROHS3 Compliant

All three parts share identical electrical performance characteristics and mechanical form factors. The part number suffix variation (E, D, G) indicates internal design or manufacturing differences that do not affect interchangeability for the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2E2.5UM, 2D2.5UM, and 2G2.5UM—are active products with identical electrical and mechanical specifications. Selection between these equivalents should be based on:

1. Certification Requirements: The 2D2.5UM includes VDE approval in addition to CSA and UL508, making it suitable for applications requiring European compliance standards.

2. Availability: Current inventory levels are 1,060 units (2E2.5UM), 902 units (2D2.5UM), and 1,133 units (2G2.5UM). Part selection may be influenced by supply chain lead times and stock status.

3. Application Compliance: For North American applications, 2E2.5UM and 2G2.5UM with CSA and UL508 certification are appropriate. For applications requiring international compliance, 2D2.5UM with VDE certification is the preferred choice.

Frequently Asked Questions (FAQ)

Q: Can 2D2.5UM be used as a direct replacement for 2E2.5UM?

A: Yes. Both parts share identical current rating (2.5A), voltage ratings (480V AC, 80V DC), breaker type (thermal magnetic), mounting configuration (DIN Rail), pole count (2), and actuator type (lever). The 2D2.5UM includes additional VDE certification.

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

A: All three parts are parametrically equivalent with identical electrical and mechanical performance. The suffix variation indicates internal design differences. The 2D2.5UM includes VDE approval; 2E2.5UM and 2G2.5UM carry CSA and UL508 certification.

Q: Are these parts interchangeable in existing installations?

A: Yes. The identical specifications for current rating, voltage ratings, mounting type, pole configuration, and actuator type ensure mechanical and electrical interchangeability in DIN Rail-mounted applications.

Q: Which part should be selected for European market applications?

A: The 2D2.5UM is recommended for European applications due to its VDE certification in addition to CSA and UL508 approvals.

Q: Is packaging identical across all three substitute parts?

A: Yes. All three parts are supplied in bulk packaging.
