1D6UM 6A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 1D6UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 6A current with 480 V AC and 42 V DC voltage ratings. This single-pole DIN rail-mounted breaker features lever actuation and is certified by CSA, UL508, and VDE. The product is active and ROHS3 compliant, with 1162 units currently in stock.

Alternative models within the V-EA series become necessary when application voltage requirements differ from the 480 V AC specification, or when inventory constraints require sourcing from available stock levels.

Substitute Part Grouping Explanation

Substitution within the 1D6UM family is determined by the following parameters:

Current Rating: 6A (fixed across all substitutes)
Breaker Type: Thermal Magnetic (fixed across all substitutes)
Mounting Type: DIN Rail (fixed across all substitutes)
Actuator Type: Lever (fixed across all substitutes)
Number of Poles: 1 (fixed across all substitutes)
Voltage Rating - DC: 42 V (fixed across all substitutes)
Packaging: Bulk (fixed across all substitutes)
Series: V-EA (fixed across all substitutes)

The primary differentiator among substitute parts is the AC voltage rating. The 1D6UM operates at 480 V AC, while substitute models 1B6UM, 1E6UM, 1G6UM, and 1Z6UM operate at either 480 V AC (1B6UM) or 277 V AC (1E6UM, 1G6UM, 1Z6UM). All substitute parts maintain identical mechanical, electrical, and certification characteristics within their respective voltage classes.

Engineering Selection Recommendations

480 V AC Applications: The 1D6UM and 1B6UM are electrically equivalent for 480 V AC systems. Both carry CSA, UL508, and VDE certifications. Selection between these two should be based on inventory availability and lead time requirements.

277 V AC Applications: The 1E6UM, 1G6UM, and 1Z6UM are electrically equivalent for 277 V AC systems. All three carry CSA and UL508 certifications. Note that these models do not carry VDE certification. Selection among these three should be based on inventory availability and application requirements.

Cross-Voltage Substitution: The 1D6UM (480 V AC) cannot be substituted with 277 V AC models (1E6UM, 1G6UM, 1Z6UM) without circuit redesign. Conversely, 277 V AC models cannot be used in 480 V AC applications.

All substitute parts maintain identical mechanical form factor, DIN rail mounting compatibility, and thermal-magnetic trip characteristics as the 1D6UM.

Frequently Asked Questions (FAQ)

Q: Can I use 1E6UM, 1G6UM, or 1Z6UM as a direct replacement for 1D6UM?

A: No. The 1D6UM is rated for 480 V AC, while 1E6UM, 1G6UM, and 1Z6UM are rated for 277 V AC. Direct substitution is not permitted without circuit voltage verification and redesign.

Q: What is the difference between 1D6UM and 1B6UM?

A: Both are rated for 480 V AC, 6A, and share identical electrical and mechanical specifications. The primary difference is inventory availability. Both carry full CSA, UL508, and VDE certifications.

Q: Are 1E6UM, 1G6UM, and 1Z6UM interchangeable?

A: Yes, for 277 V AC applications. All three are rated for 6A, 277 V AC, 42 V DC, and share identical thermal-magnetic characteristics, DIN rail mounting, and lever actuation. Selection should be based on inventory and application-specific requirements.

Q: Do all substitute parts carry the same certifications as 1D6UM?

A: No. The 1D6UM and 1B6UM carry CSA, UL508, and VDE certifications. The 1E6UM, 1G6UM, and 1Z6UM carry CSA and UL508 certifications only. VDE certification is not available for the 277 V AC models.

Q: Can these circuit breakers be used in DC applications?

A: All models are rated for 42 V DC. DC application suitability must be verified against specific circuit requirements and load characteristics.

Q: What is the packaging format for all substitute parts?

A: All parts are supplied in Bulk packaging format.
