3D6UM Equivalent & Substitute Parts Reference

Part Overview

The 3D6UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This DIN rail-mounted device is designed for 6A current protection in AC and DC applications up to 480V AC and 80V DC respectively. The part is currently active in production with full inventory availability. Equivalent substitute parts are necessary when the primary part is unavailable, when managing supply chain redundancy, or when integrating components from existing stock across multiple procurement channels.

Substitute Part Grouping Explanation

The 3D6UM has three parametric equivalents within the Altech V-EA series: 3B6UM, 3E6UM, and 3G6UM. These parts are interchangeable based on the following criteria:

All substitute parts share identical electrical and mechanical specifications:

• Current Rating: 6A
• Voltage Rating: 480V AC / 80V DC
• Breaker Type: Thermal Magnetic
• Number of Poles: 3
• Mounting Type: DIN Rail
• Actuator Type: Lever
• Series: V-EA
• Packaging: Bulk
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The substitution is valid across all four part numbers (3D6UM, 3B6UM, 3E6UM, 3G6UM) because they maintain identical functional parameters within the allowed electrical and mechanical specifications for this product category.

Parameter Comparison

Engineering Selection Recommendations

All four parts (3D6UM, 3B6UM, 3E6UM, 3G6UM) are active products with full regulatory compliance. The 3D6UM and 3B6UM carry CSA, UL508, and VDE approvals, while 3E6UM and 3G6UM carry CSA and UL508 approvals. Selection between these parts should be based on:

1. Regulatory requirements specific to the application. If VDE certification is mandatory, use 3D6UM or 3B6UM.
2. Inventory availability and supply chain considerations. All parts maintain adequate stock levels.
3. Procurement lead times and cost factors specific to your supply chain.

All parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Frequently Asked Questions (FAQ)

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

A: Yes. All four parts share identical electrical ratings (6A, 480V AC, 80V DC), breaker type (thermal magnetic), pole configuration (3-pole), mounting method (DIN rail), and actuator type (lever). They are parametric equivalents within the V-EA series.

Q: Are there differences in approval certifications between these parts?

A: The 3D6UM and 3B6UM include VDE certification in addition to CSA and UL508. The 3E6UM and 3G6UM carry CSA and UL508 certifications. Verify certification requirements for your specific application before substitution.

Q: Do all substitute parts have the same physical dimensions and DIN rail compatibility?

A: Yes. All parts are DIN rail-mounted with identical mounting specifications and are mechanically interchangeable.

Q: What is the difference between the part number designations (D, B, E, G)?

A: The letter designation (D, B, E, G) identifies the thermal characteristic curve of the breaker. All variants maintain the same 6A current rating and voltage specifications but may have different trip characteristics. Consult the manufacturer's technical documentation for specific thermal curve data.

Q: Are all parts RoHS and REACH compliant?

A: Yes. All four parts are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.
