Altech Corporation 3B6UM Circuit Breaker Equivalent & Substitute Parts

Part Overview

The Altech Corporation 3B6UM is a three-pole thermal magnetic circuit breaker rated for 6A at 480V AC and 80V DC, designed for DIN rail mounting with lever actuation. This component is classified as Active product status and is ROHS3 compliant. Substitute parts become necessary when the primary part number is unavailable, when inventory constraints require alternative sourcing, or when operational requirements align with equivalent thermal magnetic characteristics within the V-EA series.

Substitute Part Grouping Explanation

All substitute parts listed—3D6UM, 3E6UM, and 3G6UM—are parametric equivalents within the Altech V-EA series. Substitution is valid based on the following criteria:

• Current Rating: All parts rated at 6A
• Voltage Rating: All parts rated at 480V AC and 80V DC
• Breaker Type: All parts are thermal magnetic
• Mounting Configuration: All parts mount on DIN rail with lever actuation
• Number of Poles: All parts are three-pole configurations
• Compliance: All parts maintain ROHS3 compliance and REACH unaffected status

The primary distinction between these parts lies in their thermal magnetic trip characteristics (B, D, E, and G curve designations), which determine the speed of response to overcurrent conditions. Selection among these equivalents depends on the specific thermal magnetic curve requirement for the application.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain Active product status and ROHS3 compliance. The 3B6UM and 3D6UM both carry CSA, UL508, and VDE approvals, while 3E6UM and 3G6UM carry CSA and UL508 approvals. Selection should be based on the specific approval requirements of the target application and the thermal magnetic curve specification needed for overcurrent protection performance.

Frequently Asked Questions (FAQ)

Q: Can 3D6UM, 3E6UM, and 3G6UM be used interchangeably with 3B6UM?

A: These parts are parametric equivalents in current rating, voltage rating, pole configuration, and mounting type. Interchangeability depends on whether the application requires the specific thermal magnetic curve of the B characteristic. If the application specifies a different curve requirement (D, E, or G), the corresponding part number should be selected.

Q: What is the difference between the B, D, E, and G designations?

A: These designations represent different thermal magnetic trip curves that define the speed of response to overcurrent conditions. The specific curve requirement is determined by the application's protection scheme and must be verified against system design specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all four parts listed are ROHS3 compliant and REACH unaffected.

Q: What are the approval agency differences between these parts?

A: The 3B6UM and 3D6UM carry CSA, UL508, and VDE approvals. The 3E6UM and 3G6UM carry CSA and UL508 approvals. Application requirements may dictate which approval set is necessary.

Q: Are these parts available in different packaging options?

A: All parts listed are supplied in Bulk packaging.
