3E6UM 6A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 3E6UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 6A at 480V AC and 80V DC. This DIN rail-mounted device features a lever actuator and three-pole configuration, designed for industrial electrical distribution and protection applications. The product is currently active in inventory with 872 units in stock. Equivalent substitute parts are necessary when the primary model is unavailable, when inventory constraints require alternative sourcing, or when application-specific thermal-magnetic characteristics necessitate selection from the V-EA series alternatives.

Substitute Part Grouping Explanation

All substitute parts for the 3E6UM are parametric equivalents within the Altech Corporation V-EA series. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Current Rating: 6A (identical across all substitutes)
• Voltage Rating - AC: 480V (identical across all substitutes)
• Voltage Rating - DC: 80V (identical across all substitutes)
• Number of Poles: 3 (identical across all substitutes)
• Mounting Type: DIN Rail (identical across all substitutes)
• Actuator Type: Lever (identical across all substitutes)
• Breaker Type: Thermal Magnetic (identical across all substitutes)
• RoHS Status: ROHS3 Compliant (identical across all substitutes)

The primary distinction among substitute parts lies in their thermal-magnetic trip characteristics, designated by the letter designation in the part number (B, D, E, G). These designations define the specific trip curve and response time profile of each breaker, allowing selection based on application-specific load characteristics and protection requirements.

Parameter Comparison

Engineering Selection Recommendations

All four circuit breaker models (3E6UM, 3B6UM, 3D6UM, 3G6UM) maintain active product status and full compliance with CSA and UL508 certifications. The 3B6UM and 3D6UM variants carry additional VDE approval, providing expanded geographic compliance for European applications. All parts are ROHS3 compliant and electrically and mechanically interchangeable within DIN rail-mounted three-pole 6A 480V AC / 80V DC installations.

Selection among these equivalents is determined by application-specific thermal-magnetic trip curve requirements. The letter designation (B, D, E, G) in each part number corresponds to distinct trip characteristics that define response behavior under normal operation, inrush conditions, and fault conditions. Component selection should be based on the specific load profile and protection coordination requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Are the 3E6UM, 3B6UM, 3D6UM, and 3G6UM directly interchangeable?

A: Yes, these parts are direct parametric equivalents. All share identical electrical ratings (6A, 480V AC, 80V DC), mechanical configuration (3-pole, DIN rail mount, lever actuator), and physical form factor. They are mechanically and electrically interchangeable in any installation designed for 6A three-pole thermal magnetic circuit breakers.

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

A: These letters designate distinct thermal-magnetic trip curve profiles. Each curve defines the specific response time and trip threshold under various load conditions. Selection depends on the application's load characteristics and required protection coordination with upstream and downstream devices.

Q: Which substitute part has the highest inventory availability?

A: The 3D6UM variant has the highest current inventory with 1120 units in stock, followed by 3G6UM (1025 units), 3E6UM (872 units), and 3B6UM (723 units).

Q: Do all substitute parts carry the same certifications?

A: The 3E6UM and 3G6UM carry CSA and UL508 approvals. The 3B6UM and 3D6UM carry CSA, UL508, and VDE approvals. All parts meet ROHS3 compliance requirements.

Q: Can I use a substitute part if my application specifies the 3E6UM?

A: Substitution is permissible only if the application requirements allow for the specific thermal-magnetic trip characteristics of the alternative part. Consult application documentation and load analysis to confirm compatibility with the substitute's trip curve profile.
