2Z2.5UM Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2Z2.5UM 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 with a lever actuator and two poles. The product is active and widely available with 773 units in stock. Alternative models within the same electrical and mechanical parameter set are necessary for supply chain flexibility, regional availability, or specific application requirements where different thermal-magnetic characteristics are needed.

Key Parameters

Substitute Part Grouping Explanation

The substitute parts 2D2.5UM, 2E2.5UM, and 2G2.5UM are parametric equivalents to the 2Z2.5UM based on the following criteria:

All substitute parts share identical electrical specifications: 2.5A current rating, 480V AC and 80V DC voltage ratings, thermal magnetic breaker type, and lever actuator configuration. All are mounted on DIN rail with two poles and belong to the V-EA series. The primary distinction between these models lies in their thermal-magnetic trip characteristics, indicated by the letter designation (Z, D, E, G), which determines the specific response curve and protection profile for different load types and applications. All models maintain the same physical form factor, mounting interface, and regulatory compliance framework.

Parameter Comparison

Engineering Selection Recommendations

Selection among 2Z2.5UM, 2D2.5UM, 2E2.5UM, and 2G2.5UM should be based on application-specific thermal-magnetic trip curve requirements and regional compliance needs. The 2D2.5UM includes VDE certification in addition to CSA and UL508, making it suitable for applications requiring European standards compliance. All four models maintain ROHS3 compliance and REACH unaffected status, ensuring environmental regulatory alignment. Inventory availability ranges from 773 to 1133 units across the four models, supporting supply chain continuity. Selection should prioritize the specific trip characteristic curve (Z, D, E, or G designation) required by the circuit protection design, as this parameter determines the breaker's response to thermal and magnetic fault conditions.

Frequently Asked Questions (FAQ)

Q: Can 2D2.5UM, 2E2.5UM, and 2G2.5UM be used interchangeably with 2Z2.5UM?

A: These parts are parametric equivalents sharing identical electrical ratings (2.5A, 480V AC, 80V DC), mounting type (DIN rail), pole configuration (2 poles), and actuator type (lever). Interchangeability depends on whether the application requires a specific thermal-magnetic trip curve. The letter designation (Z, D, E, G) indicates different trip characteristics; substitution is valid only if the replacement curve meets the circuit protection requirements.

Q: What is the significance of the letter designation in the part number?

A: The letter designation (Z, D, E, G) identifies the thermal-magnetic trip curve classification. Each curve provides different response characteristics for thermal overload and magnetic fault conditions. Selection must match the intended application's protection profile.

Q: Are all four models certified to the same standards?

A: All models carry CSA and UL508 certifications. The 2D2.5UM additionally includes VDE certification, which may be required for specific regional or customer specifications.

Q: What is the packaging format for these circuit breakers?

A: All four models are supplied in bulk packaging, suitable for direct integration into DIN rail assemblies.

Q: Do these breakers require any special handling or storage considerations?

A: Moisture Sensitivity Level is not applicable to these components, indicating standard industrial storage conditions are acceptable. No special environmental controls are required.
