Altech Corporation 2C20UM 20A Thermal Magnetic Circuit Breaker

Part Overview

The 2C20UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, designed for DIN rail mounting applications. This 20-ampere, 2-pole breaker operates at 480V AC and 80V DC with lever actuation. The product maintains active status with full compliance to CSA, UL508, and VDE standards. Equivalent substitute parts are available within the V-EA series to support procurement flexibility and inventory management across multiple channel designations.

Substitute Part Grouping Explanation

The 2C20UM circuit breaker has four parametric equivalents within the Altech V-EA series: 2D20UM, 2E20UM, 2G20UM, and 2Z20UM. These parts share identical electrical and mechanical specifications across all critical substitution parameters:

Key Parameters Determining Substitution:

• Current Rating: 20A (all equivalents)
• Voltage Rating - AC: 480V (all equivalents)
• Voltage Rating - DC: 80V (all equivalents)
• Breaker Type: Thermal Magnetic (all equivalents)
• Number of Poles: 2 (all equivalents)
• Mounting Type: DIN Rail (all equivalents)
• Actuator Type: Lever (all equivalents)
• Series: V-EA (all equivalents)
• Packaging: Bulk (all equivalents)

The substitution relationship is based on functional equivalence across these parameters. The alphanumeric designations (C, D, E, G, Z) represent channel variants within the same product family and do not affect electrical or mechanical performance in the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

All five circuit breaker models (2C20UM, 2D20UM, 2E20UM, 2G20UM, 2Z20UM) are active products with ROHS3 compliance and maintain equivalent electrical and mechanical specifications. The 2C20UM, 2D20UM, and 2E20UM variants carry full CSA, UL508, and VDE certifications. The 2G20UM and 2Z20UM variants carry CSA and UL508 certifications. Selection between these equivalents should be based on certification requirements for the specific application and channel availability. All parts are suitable for direct substitution in 20-ampere, 480V AC / 80V DC, 2-pole DIN rail applications with lever actuation.

Frequently Asked Questions (FAQ)

Q: Can 2D20UM, 2E20UM, 2G20UM, or 2Z20UM be used as direct replacements for 2C20UM?

A: Yes. All five part numbers share identical electrical ratings (20A, 480V AC, 80V DC), breaker type (thermal magnetic), pole configuration (2-pole), mounting method (DIN rail), and actuation mechanism (lever). They are parametric equivalents within the V-EA series.

Q: Are there differences in certification between these substitute parts?

A: The 2C20UM, 2D20UM, and 2E20UM carry CSA, UL508, and VDE approvals. The 2G20UM and 2Z20UM carry CSA and UL508 approvals. Verify certification requirements for your specific application before selection.

Q: What do the different letter designations (C, D, E, G, Z) represent?

A: The letter designations represent channel variants within the Altech V-EA series. They do not affect electrical performance, mechanical compatibility, or functional operation in the specified application envelope.

Q: Are all substitute parts available in the same packaging?

A: Yes. All five part numbers are supplied in bulk packaging.

Q: Can these circuit breakers be used interchangeably in existing installations?

A: Yes, provided the installation operates within the specified electrical parameters (20A, 480V AC, 80V DC) and uses DIN rail mounting. Physical dimensions and mounting footprint are identical across all variants.
