Altech Corporation 2G16UM Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2G16UM is a thermal magnetic circuit breaker rated for 16A at 480V AC and 80V DC, designed for DIN rail mounting with lever actuation. This two-pole breaker is part of the V-EA series and maintains active product status with full CSA and UL508 approvals. Substitute parts are identified when identical electrical and mechanical parameters are required for circuit protection applications, ensuring continuity in system design and component availability across manufacturing batches and inventory sources.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2G16UM are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

• Current Rating: 16A (exact match required)
• Voltage Rating - AC: 480V (exact match required)
• Voltage Rating - DC: 80V (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Number of Poles: 2 (exact match required)
• Actuator Type: Lever (exact match required)
• Series: V-EA (exact match required)
• Manufacturer: Altech Corporation (exact match required)

All substitute parts listed below meet these criteria and are therefore electrically and mechanically interchangeable with the 2G16UM in applications requiring a 16A thermal magnetic DIN rail circuit breaker.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (2B16UM, 2C16UM, 2D16UM) are active products with full compliance to ROHS3 standards and CSA/UL508 certifications. The 2B16UM, 2C16UM, and 2D16UM variants include additional VDE approval, providing expanded regulatory coverage for European applications. Selection among these interchangeable parts should be based on inventory availability and regional compliance requirements. All parts are supplied in bulk packaging and maintain identical electrical performance and mechanical form factor for direct substitution in DIN rail installations.

Frequently Asked Questions (FAQ)

Q: Can 2B16UM, 2C16UM, and 2D16UM be used interchangeably with 2G16UM?

A: Yes. All four part numbers are parametrically equivalent across current rating (16A), voltage ratings (480V AC / 80V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), pole count (2), and actuator type (lever). They are direct substitutes for applications requiring these specifications.

Q: What is the difference between 2G16UM and the substitute parts?

A: The primary difference is regulatory approval scope. The 2B16UM, 2C16UM, and 2D16UM include VDE certification in addition to CSA and UL508 approvals, making them suitable for applications requiring European compliance. All other electrical and mechanical parameters are identical.

Q: Are these parts compatible with existing DIN rail installations?

A: Yes. All parts share identical mounting type (DIN rail), form factor, and mechanical specifications, ensuring direct compatibility with existing installations without modification.

Q: What packaging is available for these circuit breakers?

A: All parts are supplied in bulk packaging, suitable for integration into larger assemblies or distribution systems.

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

A: Moisture Sensitivity Level is not applicable to these components, and REACH status is unaffected, indicating standard industrial handling and storage practices are appropriate.
