2G1UM 1A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2G1UM is an active thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 1A at 480V AC and 80V DC. This DIN rail-mounted device features a lever actuator and dual-pole configuration. The part is ROHS3 compliant and holds CSA and UL508 approvals. Substitute parts become necessary when the primary part is unavailable, when inventory constraints require alternative sourcing, or when specific thermal-magnetic characteristics (G, B, C, D, or 3 curve designations) are acceptable for the application.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts for the 2G1UM maintain identical electrical and mechanical specifications across the following critical parameters: 1A current rating, 480V AC and 80V DC voltage ratings, thermal magnetic breaker type, DIN rail mounting, lever actuator, and dual-pole configuration. The substitutes differ only in their thermal-magnetic trip curve designation (G, B, C, D, or 3), which defines the speed of thermal and magnetic response to overcurrent conditions. All substitute parts are manufactured by Altech Corporation within the V-EA series and share the same packaging format (Bulk). Substitution is valid when the specific trip curve characteristic is interchangeable for the intended application.

Parameter Comparison

Engineering Selection Recommendations

All five parts maintain active product status and ROHS3 compliance. The 2G1UM, 2B1UM, and 2E1UM hold CSA and UL508 certifications. The 2C1UM and 2D1UM extend approvals to include VDE certification, providing additional regulatory coverage for European applications. Selection between these parts depends on certification requirements for the target market and the acceptability of the specific thermal-magnetic trip curve for the circuit protection scheme. Parts with VDE approval (2C1UM, 2D1UM) are suitable for applications requiring broader international compliance.

Frequently Asked Questions (FAQ)

Q: Can 2B1UM, 2C1UM, 2D1UM, and 2E1UM be used interchangeably with 2G1UM?

A: Yes, these parts are parametric equivalents. All share identical current rating (1A), voltage ratings (480V AC, 80V DC), mounting type (DIN Rail), pole configuration (2), and actuator type (Lever). Substitution is valid when the thermal-magnetic trip curve characteristic is acceptable for the application.

Q: What is the difference between the G, B, C, D, and 3 designations?

A: These designations represent different thermal-magnetic trip curve characteristics that define the speed of response to overcurrent conditions. The specific curve must be compatible with the circuit protection requirements of the application.

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

A: The 2G1UM, 2B1UM, and 2E1UM carry CSA and UL508 approvals. The 2C1UM and 2D1UM include additional VDE certification, making them suitable for applications requiring European regulatory compliance.

Q: Does packaging differ between these parts?

A: All parts are supplied in Bulk packaging format with no differences in package configuration.

Q: Which part has the highest current inventory?

A: The 2G1UM has the highest inventory at 1073 pieces, followed by 2E1UM at 1006 pieces.
