3G6UM Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 3G6UM is a three-pole thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 6A at 480V AC and 80V DC operation. This DIN rail-mounted device features lever actuation and is part of the V-EA series. The product is currently active with full inventory availability (1025 pcs in stock). Finding equivalent substitute parts is necessary to ensure supply chain flexibility, manage inventory optimization, and maintain operational continuity when the primary part becomes unavailable or when alternative thermal characteristics are required for specific circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

The 3G6UM circuit breaker has three parametric equivalents within the Altech Corporation V-EA series: 3B6UM, 3D6UM, and 3E6UM. These parts are interchangeable based on the following critical parameters that remain constant across all variants:

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

The primary distinction between these parts lies in their thermal characteristic designation (G, B, D, and E), which defines the trip curve behavior. All four parts maintain identical electrical and mechanical specifications, enabling direct substitution in applications where the specific thermal characteristic is compatible with circuit protection requirements.

Parameter Comparison

Engineering Selection Recommendations

All four circuit breaker variants (3G6UM, 3B6UM, 3D6UM, 3E6UM) maintain active product status and full compliance with regulatory requirements. Selection between these parts should be based on:

1. Thermal Characteristic Requirement: The letter designation (G, B, D, E) indicates the trip curve classification. Verify that the selected thermal characteristic aligns with the circuit protection strategy for the target application.

2. Regulatory Compliance: Parts 3B6UM and 3D6UM carry additional VDE certification beyond CSA and UL508. If VDE compliance is mandated by regional standards or customer specifications, these variants are preferred.

3. Inventory Availability: All parts are in active stock. The 3D6UM offers the highest inventory level (1120 pcs), followed by 3G6UM (1025 pcs), 3E6UM (872 pcs), and 3B6UM (723 pcs).

4. Mechanical and Electrical Compatibility: All variants are mechanically and electrically interchangeable within the specified voltage and current parameters. Direct substitution is permissible without modification to mounting hardware or electrical connections.

Frequently Asked Questions (FAQ)

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

A: Yes, these parts are parametric equivalents. All maintain identical current ratings (6A), voltage ratings (480V AC / 80V DC), pole configuration (3-pole), mounting type (DIN Rail), and actuator type (Lever). The primary difference is the thermal characteristic designation, which defines the trip curve behavior. Substitution is valid when the thermal characteristic of the replacement part is compatible with the circuit protection requirements.

Q: What is the significance of the thermal characteristic letter (G, B, D, E)?

A: The thermal characteristic letter designates the trip curve classification of the circuit breaker. This parameter determines the time-current relationship and the breaker's response to overcurrent conditions. Selection must align with the specific protection strategy required for the protected circuit.

Q: Are there any compliance differences between the substitute parts?

A: The 3B6UM and 3D6UM carry VDE certification in addition to CSA and UL508 approvals. The 3G6UM and 3E6UM are certified by CSA and UL508. If regional standards or customer specifications mandate VDE compliance, the 3B6UM or 3D6UM variants are required.

Q: Is the packaging identical across all variants?

A: Yes, all four parts are supplied in bulk packaging. No special handling or storage modifications are required when transitioning between variants.

Q: What is the inventory status for each substitute part?

A: All parts are currently in active stock: 3G6UM (1025 pcs), 3B6UM (723 pcs), 3D6UM (1120 pcs), and 3E6UM (872 pcs). Inventory levels support immediate procurement without lead time constraints.

Q: Are mechanical modifications required when substituting these parts?

A: No. All variants are designed for identical DIN rail mounting with lever actuation. Direct mechanical substitution is possible without hardware changes or panel modifications.
