2Z05UM 0.5A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2Z05UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 500mA at 480V AC and 80V DC. This DIN rail-mounted breaker features a lever actuator and is part of the V-EA series. The product is active and widely stocked, with 896 units currently available. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, manage inventory across multiple locations, and maintain operational continuity when the primary part number becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2Z05UM is determined by strict equivalence across the following critical parameters:

• Breaker Type: Thermal Magnetic
• Current Rating: 500mA
• Voltage Rating - AC: 480V
• Voltage Rating - DC: 80V
• Mounting Type: DIN Rail
• Actuator Type: Lever
• Number of Poles: 2
• Series: V-EA
• Packaging: Bulk
• RoHS Status: ROHS3 Compliant

The substitute parts 2D05UM and 2E05UM meet all electrical and mechanical parameters required for direct substitution with the 2Z05UM. All three parts share identical ratings, mounting specifications, and regulatory compliance status. Differences in approval agencies (2D05UM includes VDE certification in addition to CSA and UL508) do not restrict substitution capability.

Parameter Comparison

Engineering Selection Recommendations

All three circuit breaker models—2Z05UM, 2D05UM, and 2E05UM—are active products with full regulatory compliance. Selection between these parts should be based on inventory availability and regional certification requirements.

The 2D05UM provides additional VDE certification beyond the CSA and UL508 approvals present in both the 2Z05UM and 2E05UM. This extended certification may be required for applications in European markets or systems requiring multi-regional compliance documentation.

The 2E05UM currently maintains the highest inventory level at 1145 units, followed by the 2Z05UM at 896 units and the 2D05UM at 676 units. All parts are manufactured by Altech Corporation and carry ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can 2D05UM or 2E05UM be used as direct replacements for 2Z05UM?

A: Yes. All three parts are parametrically equivalent across all critical electrical and mechanical specifications: 500mA current rating, 480V AC / 80V DC voltage ratings, thermal magnetic operation, DIN rail mounting, lever actuation, and 2-pole configuration.

Q: What is the difference between these three part numbers?

A: The primary differences are manufacturer designations (Z, D, E channel designations) and approval certifications. The 2D05UM includes VDE certification in addition to CSA and UL508. All other electrical and mechanical parameters are identical.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. All three parts share identical mounting specifications, electrical ratings, and physical form factors for DIN rail installation.

Q: Which part should I select if I need European market compliance?

A: The 2D05UM includes VDE certification, which may be required for certain European applications. The 2Z05UM and 2E05UM carry CSA and UL508 certifications.

Q: Are all three parts currently in stock?

A: Yes. The 2Z05UM has 896 units available, the 2D05UM has 676 units available, and the 2E05UM has 1145 units available.

Q: Do these parts have any environmental or regulatory restrictions?

A: All three parts are ROHS3 compliant and REACH unaffected. No moisture sensitivity level applies to these components.
