Altech Corporation 2E10UM 10A Thermal Magnetic Circuit Breaker

Part Overview

The 2E10UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, designed for DIN rail mounting applications. This 10A rated breaker operates across 480V AC and 80V DC systems with a lever-actuated mechanism and dual-pole configuration. The product maintains active status with full RoHS3 compliance and CSA/UL508 approvals, making it suitable for industrial control and distribution applications where overcurrent protection is required.

Substitute parts become necessary when addressing supply chain constraints, regional certification requirements, or specific thermal-magnetic characteristic variations within the same electrical specification envelope.

Substitute Part Grouping Explanation

The 2E10UM qualifies for direct substitution with three alternative part numbers within the Altech V-EA series: 2C10UM, 2D10UM, and 2G10UM. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Current Rating: 10A (all substitutes match)
• Voltage Rating: 480V AC / 80V DC (all substitutes match)
• Mounting Configuration: DIN Rail (all substitutes match)
• Breaker Technology: Thermal Magnetic (all substitutes match)
• Actuator Mechanism: Lever (all substitutes match)
• Pole Configuration: 2-pole (all substitutes match)
• Series Classification: V-EA (all substitutes match)
• Regulatory Compliance: CSA and UL508 (all substitutes certified)
• Environmental Status: ROHS3 Compliant, REACH Unaffected (all substitutes match)

The letter designations (C, D, E, G) within the base product numbers indicate thermal-magnetic characteristic variations that remain within acceptable operating parameters for the specified electrical envelope. These variations allow for application-specific tuning while maintaining full electrical and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All four part numbers maintain active product status with full regulatory compliance. Selection between 2E10UM, 2C10UM, 2D10UM, and 2G10UM should be based on regional certification requirements and supply availability.

For applications requiring VDE certification in addition to CSA and UL508, 2C10UM and 2D10UM are the appropriate selections. Both parts carry VDE approval alongside North American certifications.

For applications where CSA and UL508 certifications are the sole requirement, 2E10UM and 2G10UM provide equivalent functionality with identical electrical and mechanical specifications.

All substitutes carry ROHS3 compliance and REACH unaffected status, ensuring environmental regulatory alignment across the entire substitution group.

Frequently Asked Questions (FAQ)

Q: Can 2C10UM, 2D10UM, and 2G10UM be used interchangeably with 2E10UM in the same circuit?

A: Yes. All four part numbers share identical electrical ratings (10A, 480V AC, 80V DC), mounting configuration (DIN Rail), pole count (2), and actuator type (Lever). They are mechanically and electrically interchangeable within the V-EA series.

Q: What is the difference between the letter designations (C, D, E, G) in these part numbers?

A: The letter designations indicate thermal-magnetic characteristic variations within the V-EA series. These variations define the trip curve behavior under fault conditions while maintaining compliance with the specified 10A current rating and voltage envelope.

Q: Are there regional certification differences between these substitutes?

A: Yes. 2C10UM and 2D10UM carry VDE certification in addition to CSA and UL508. 2E10UM and 2G10UM carry CSA and UL508 only. Select based on your regional certification requirements.

Q: Do all substitutes have the same packaging and inventory status?

A: All four parts are supplied in Bulk packaging. Current inventory levels vary: 2E10UM (1100 pcs), 2C10UM (1161 pcs), 2D10UM (1018 pcs), and 2G10UM (857 pcs). All are listed as New Original In Stock.

Q: Are these parts RoHS and REACH compliant?

A: Yes. All four part numbers are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulatory requirements.

Q: Can I substitute a 2E10UM with a 2C10UM in an existing installation?

A: Yes, provided your application does not require VDE certification. If VDE certification is mandated, 2C10UM is the appropriate choice. Otherwise, both parts are electrically and mechanically equivalent for DIN rail mounted 10A thermal magnetic protection circuits.
