2G2.5UM Thermal Magnetic Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The 2G2.5UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 2.5A at 480V AC and 80V DC. This DIN Rail-mounted breaker is part of the V-EA series and maintains Active product status with full CSA and UL508 approval. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the V-EA series, ensuring functional interchangeability in DIN Rail installations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2G2.5UM are identified based on strict parameter matching within the Altech V-EA series. All substitute parts maintain identical electrical specifications: 2.5A current rating, 480V AC and 80V DC voltage ratings, thermal magnetic operation, and 2-pole lever-actuated configuration on DIN Rail mounting. The substitution logic is based exclusively on these core parameters: current rating, voltage ratings, breaker type, mounting configuration, and pole count. Parts 2D2.5UM and 2E2.5UM meet all these criteria and are therefore classified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2G2.5UM, 2D2.5UM, and 2E2.5UM—are Active products with identical electrical and mechanical specifications. Selection between these parts is based on regulatory compliance requirements and inventory availability. The 2D2.5UM includes VDE approval in addition to CSA and UL508, providing broader international certification coverage. All parts maintain ROHS3 compliance and REACH unaffected status. Inventory levels are: 2G2.5UM (1133 pcs), 2D2.5UM (902 pcs), and 2E2.5UM (1060 pcs). Part selection should prioritize application-specific certification requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can 2D2.5UM replace 2G2.5UM in all applications? A: Yes. Both parts share identical electrical ratings (2.5A, 480V AC, 80V DC), breaker type (thermal magnetic), mounting configuration (DIN Rail), and pole count (2-pole). The 2D2.5UM includes additional VDE certification, making it suitable for applications requiring broader international compliance.

Q: What is the difference between 2G2.5UM and 2E2.5UM? A: These parts are parametric equivalents with identical electrical and mechanical specifications. Both are rated 2.5A at 480V AC and 80V DC with 2-pole lever-actuated thermal magnetic operation on DIN Rail. Approval agencies differ slightly: 2G2.5UM carries CSA and UL508, while 2E2.5UM carries the same certifications.

Q: Are all three parts interchangeable? A: Yes. The 2G2.5UM, 2D2.5UM, and 2E2.5UM are parametric equivalents within the V-EA series. All maintain identical current ratings, voltage ratings, breaker type, mounting type, actuator type, and pole count. Selection depends on certification requirements and availability.

Q: What certifications apply to these circuit breakers? A: All three parts carry CSA and UL508 approval. The 2D2.5UM additionally carries VDE certification. All parts are ROHS3 compliant and REACH unaffected.

Q: Does packaging differ between substitute parts? A: No. All three parts are supplied in Bulk packaging.
