Altech Corporation 2C8UM Circuit Breaker Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2C8UM is a thermal magnetic circuit breaker rated for 8A at 480V AC and 80V DC, configured as a 2-pole DIN rail mounted device with lever actuation. This component is classified as Active product status and carries full compliance with CSA, UL508, and VDE approval agencies. Substitute parts become necessary when specific inventory availability fluctuates, when alternative thermal magnetic characteristics are required for application-specific trip curves, or when sourcing from alternative base product designations within the V-EA series is operationally advantageous.

Key Parameters

Substitute Part Grouping Explanation

The 2C8UM circuit breaker shares parametric equivalence with three substitute parts: 2D8UM, 2G8UM, and 2Z8UM. All four parts maintain identical electrical and mechanical specifications across the following critical parameters:

• Current Rating: 8A
• Voltage Rating: 480V AC / 80V DC
• Number of Poles: 2
• Mounting Configuration: DIN Rail
• Breaker Classification: Thermal Magnetic
• Actuator Mechanism: Lever
• Series Designation: V-EA
• RoHS Compliance: ROHS3 Compliant

The substitution logic is based strictly on these matching parameters. The primary distinction between the main part and substitutes lies in the base product number designation (2C8, 2D8, 2G8, 2Z8), which reflects different thermal magnetic trip curve characteristics (C, D, G, and Z designations respectively). These designations determine the specific trip point behavior under fault conditions while maintaining the same rated current and voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

All four parts—2C8UM, 2D8UM, 2G8UM, and 2Z8UM—maintain Active product status and carry full regulatory compliance. The 2C8UM and 2D8UM both hold CSA, UL508, and VDE certifications, while 2G8UM and 2Z8UM hold CSA and UL508 certifications. Selection between these parts should be based on application-specific requirements for thermal magnetic trip curve characteristics and regulatory certification scope. All parts are ROHS3 compliant and suitable for DIN rail installation in 480V AC / 80V DC systems requiring 8A, 2-pole protection.

Frequently Asked Questions (FAQ)

Q: Can 2D8UM, 2G8UM, or 2Z8UM be used as direct replacements for 2C8UM?

A: Yes, all four parts are parametric equivalents sharing identical electrical ratings (8A, 480V AC, 80V DC), mechanical configuration (2-pole, DIN rail, lever actuation), and breaker classification (thermal magnetic). The base product number designations (C, D, G, Z) indicate different trip curve characteristics, not incompatibility.

Q: What is the difference between the C, D, G, and Z designations?

A: These designations represent different thermal magnetic trip curve classifications. Each provides distinct trip point behavior under fault conditions while maintaining the same rated current and voltage specifications. Selection depends on application-specific protection requirements.

Q: Are there certification differences between these parts?

A: The 2C8UM and 2D8UM carry CSA, UL508, and VDE approvals. The 2G8UM and 2Z8UM carry CSA and UL508 approvals. Applications requiring VDE certification must use 2C8UM or 2D8UM.

Q: Do all parts use the same DIN rail mounting system?

A: Yes, all four parts are configured for standard DIN rail mounting with identical mechanical interfaces and lever actuation.

Q: What packaging is available for these parts?

A: All parts are supplied in Bulk packaging configuration.
