2G4UM 4A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2G4UM is an active Altech Corporation thermal magnetic circuit breaker rated for 4A at 480V AC and 80V DC, designed for DIN rail mounting with lever actuation. This two-pole breaker is certified by CSA and UL508, meeting industrial control panel requirements. Equivalent substitute parts within the V-EA series share identical electrical and mechanical specifications, differing only in thermal-magnetic trip characteristics designated by their character codes (G, C, D, E, Z). Substitute parts are necessary when specific trip curve requirements vary by application or when inventory availability necessitates alternative character designations.

Substitute Part Grouping Explanation

All substitute parts (2C4UM, 2D4UM, 2E4UM, 2Z4UM) are parametric equivalents to the 2G4UM within the V-EA series. Substitution is valid based on the following criteria:

Current Rating: 4A (identical across all parts)
Voltage Ratings: 480V AC / 80V DC (identical across all parts)
Mounting Configuration: DIN Rail, 2-pole, lever-actuated (identical across all parts)
Breaker Technology: Thermal Magnetic (identical across all parts)
Regulatory Compliance: All parts hold CSA and UL508 certifications

The character codes (G, C, D, E, Z) designate distinct thermal-magnetic trip curves. These codes represent the only functional differentiation among the substitute parts. Selection between these variants depends on application-specific trip curve requirements rather than electrical or mechanical incompatibility.

Engineering Selection Recommendations

All five part numbers (2G4UM, 2C4UM, 2D4UM, 2E4UM, 2Z4UM) are active products with identical electrical ratings, mechanical form factors, and core regulatory certifications (CSA, UL508). Selection among these equivalents should be based on:

Trip Curve Requirement: The character code (G, C, D, E, or Z) specifies the thermal-magnetic trip characteristic. Verify the application's trip curve specification before selection.
Regulatory Scope: Parts 2C4UM and 2D4UM carry additional VDE certification. If VDE compliance is required by regional standards or customer specifications, these variants are preferred.
Inventory Availability: All parts maintain active stock status. Current inventory levels range from 951 to 1169 pieces, supporting immediate procurement.
Packaging: All parts are supplied in bulk packaging, consistent with industrial distribution standards.

Frequently Asked Questions (FAQ)

Q: Can 2C4UM, 2D4UM, 2E4UM, and 2Z4UM be used interchangeably with 2G4UM?

A: Yes, these parts are parametric equivalents with identical current ratings (4A), voltage ratings (480V AC / 80V DC), mounting configuration (DIN rail, 2-pole), and actuator type (lever). The character codes designate different thermal-magnetic trip curves. Interchangeability is valid provided the application accepts the specific trip curve of the substitute part.

Q: What is the difference between the character codes (G, C, D, E, Z)?

A: The character codes represent distinct thermal-magnetic trip characteristics. These define the breaker's response time and current threshold for thermal and magnetic tripping. Selection depends on the specific protection requirements of the circuit being protected.

Q: Are all substitute parts certified to the same standards?

A: All five parts hold CSA and UL508 certifications. Additionally, 2C4UM and 2D4UM carry VDE certification. If your application requires VDE compliance, these two variants are the appropriate selections.

Q: Can I substitute a 2G4UM with a 2D4UM in an existing installation?

A: Substitution is mechanically and electrically compatible. However, verify that the trip curve designation (D character) meets the circuit protection requirements of your application. Consult the application's protection coordination study or equipment documentation to confirm trip curve compatibility.

Q: What is the packaging format for these parts?

A: All parts are supplied in bulk packaging, standard for industrial circuit breaker distribution. Confirm packaging quantity requirements with your procurement specifications.

Q: Are these parts RoHS compliant?

A: Yes, all five parts are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for industrial applications.
