2D4.6UM Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The 2D4.6UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 4.6A at 480V AC and 80V DC. This DIN Rail-mounted device features a lever actuator and dual-pole configuration, designed for industrial control and protection applications. The product is currently active in production with 851 units in stock. Equivalent substitute parts may be required due to supply chain constraints, regional availability, or inventory management needs.

Key Parameters

Substitute Part Grouping Explanation

The 2G4.6UM qualifies as a parametric equivalent to the 2D4.6UM based on matching electrical and mechanical specifications. Substitution is valid when the following criteria are met:

• Current Rating: 4.6A (identical)
• Voltage Rating - AC: 480V (identical)
• Voltage Rating - DC: 80V (identical)
• Breaker Type: Thermal Magnetic (identical)
• Mounting Type: DIN Rail (identical)
• Number of Poles: 2 (identical)
• Actuator Type: Lever (identical)
• Series: V-EA (identical)
• RoHS Status: ROHS3 Compliant (identical)

The primary distinction between these parts lies in their base product designations (2D4.6 versus 2G4.6), which reflect internal design variations within the V-EA series. Both parts maintain equivalent functional performance and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the 2D4.6UM and 2G4.6UM are active products with ROHS3 compliance and current manufacturing support. The 2D4.6UM carries CSA, UL508, and VDE certifications, while the 2G4.6UM carries CSA and UL508 certifications. Selection between these parts should be based on application-specific certification requirements. If VDE certification is mandatory for the application, the 2D4.6UM is the required choice. For applications requiring only CSA and UL508 compliance, either part is suitable. Both parts are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can the 2G4.6UM replace the 2D4.6UM in all applications?

A: The 2G4.6UM is electrically and mechanically equivalent to the 2D4.6UM for applications requiring CSA and UL508 certifications. However, if your application mandates VDE certification, the 2D4.6UM must be used, as the 2G4.6UM does not carry this approval.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by matching current rating (4.6A), AC voltage (480V), DC voltage (80V), breaker type (thermal magnetic), mounting configuration (DIN Rail), pole count (2), and actuator type (lever). Both parts meet these criteria.

Q: Are there any physical or dimensional differences between these parts?

A: The provided specifications indicate both parts are DIN Rail-mounted with identical electrical ratings and pole configurations. No dimensional variations are specified in the available data.

Q: What is the difference between the 2D and 2G base designations?

A: The base product numbers (2D4.6 versus 2G4.6) represent internal design variations within the V-EA series. Both maintain equivalent functional performance and electrical characteristics for the specified application parameters.

Q: Which part should I select for new designs?

A: Selection should be based on certification requirements. If VDE compliance is required, specify the 2D4.6UM. For applications requiring only CSA and UL508 compliance, either part is acceptable. Both are active products with current inventory availability.
