1E6UM 6A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 1E6UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 6A at 277V AC and 42V DC. This single-pole DIN rail-mounted breaker with lever actuation is part of the V-EA series and holds Active product status with full CSA and UL508 approval. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component interchangeability within specified operational constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1E6UM is determined by the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 6A
• Breaker Type: Thermal Magnetic
• Mounting Type: DIN Rail
• Number of Poles: 1
• Actuator Type: Lever
• Series: V-EA
• Product Status: Active

Voltage Compatibility Consideration: The 1E6UM operates at 277V AC and 42V DC. Substitute parts must maintain the same current rating and mechanical form factor. The 1D6UM variant operates at 480V AC while maintaining all other electrical and mechanical specifications, making it suitable for higher AC voltage applications where 6A thermal magnetic protection is required.

The 1G6UM and 1Z6UM maintain identical electrical ratings (277V AC, 42V DC, 6A) and mechanical specifications to the 1E6UM, differing only in trip characteristic designation (G and Z respectively versus E characteristic).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance. Selection between 1E6UM, 1G6UM, and 1Z6UM is determined by AC voltage requirement (277V) and trip characteristic specification. The 1D6UM extends AC voltage capability to 480V while maintaining the 6A current rating and all mechanical specifications, suitable for higher voltage distribution systems.

All parts carry CSA and UL508 certification. The 1D6UM additionally holds VDE approval, providing expanded international compliance coverage. DIN rail mounting and lever actuation are consistent across all variants, ensuring mechanical interchangeability within the V-EA series framework.

Frequently Asked Questions (FAQ)

Q: Can the 1D6UM replace the 1E6UM in a 277V AC circuit? A: The 1D6UM is rated for 480V AC operation. While it will function in a 277V AC circuit, it is designed for higher voltage applications. Use 1D6UM only when 480V AC capability is required.

Q: What is the difference between 1E6UM, 1G6UM, and 1Z6UM? A: These parts share identical electrical ratings (6A, 277V AC, 42V DC) and mechanical specifications. The letter designation (E, G, Z) indicates the trip characteristic curve. Selection depends on the specific trip characteristic required by the application.

Q: Are all substitute parts DIN rail compatible? A: Yes. All listed parts are single-pole, lever-actuated thermal magnetic breakers mounted on DIN rail, ensuring mechanical compatibility within the V-EA series.

Q: Do all parts meet the same regulatory standards? A: The 1E6UM, 1G6UM, and 1Z6UM carry CSA and UL508 certification. The 1D6UM carries CSA, UL508, and VDE certification, providing additional international compliance.

Q: What is the DC voltage rating across all variants? A: All substitute parts maintain a 42V DC rating, consistent with the 1E6UM specification.
