Altech Corporation 2E4UM 4A Thermal Magnetic Circuit Breaker Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2E4UM is a 4A thermal magnetic circuit breaker designed for DIN rail mounting with dual-pole lever actuation. This component operates across 480 V AC and 80 V DC, meeting CSA and UL508 approval standards. The 2E4UM maintains active product status with 1066 units in current inventory. Equivalent substitute parts within the V-EA series share identical electrical and mechanical specifications, enabling direct replacement in applications requiring thermal magnetic protection at 4A ratings.

Substitute Part Grouping Explanation

Substitution eligibility for the 2E4UM is determined by strict parametric equivalence across the following criteria:

Critical Substitution Parameters:

Current Rating: 4A (exact match required)
Voltage Rating - AC: 480 V (exact match required)
Voltage Rating - DC: 80 V (exact match required)
Breaker Type: Thermal Magnetic (exact match required)
Mounting Type: DIN Rail (exact match required)
Number of Poles: 2 (exact match required)
Actuator Type: Lever (exact match required)
Series: V-EA (exact match required)

All substitute parts listed below meet these parameters identically. Differences in character designation (E, C, D, G, Z) represent thermal magnetic trip curve variations within the same electrical and mechanical envelope, maintaining full interchangeability for applications requiring 4A thermal magnetic protection on DIN rail systems.

Engineering Selection Recommendations

All substitute parts maintain active product status with current manufacturing support. Selection between 2E4UM, 2C4UM, 2D4UM, 2G4UM, and 2Z4UM is determined by application-specific thermal magnetic trip curve requirements, not by electrical or mechanical compatibility.

Parts 2C4UM and 2D4UM carry expanded approval certifications including VDE compliance, providing additional regulatory coverage for European applications. Parts 2E4UM, 2G4UM, and 2Z4UM maintain CSA and UL508 certifications suitable for North American installations.

All parts comply with ROHS3 and remain REACH unaffected. Inventory availability ranges from 951 to 1169 units across the substitute group, supporting procurement flexibility.

Frequently Asked Questions (FAQ)

Q: Can 2E4UM be directly replaced with 2C4UM, 2D4UM, 2G4UM, or 2Z4UM?

A: Yes. All parts share identical electrical ratings (4A, 480 V AC, 80 V DC), mechanical configuration (2-pole lever DIN rail), and breaker type (thermal magnetic). Direct substitution is supported without circuit modification.

Q: What distinguishes the character designations (E, C, D, G, Z) in these part numbers?

A: Character designations indicate thermal magnetic trip curve variations. These curves define the time-current response characteristics but do not alter the electrical or mechanical interface. Selection depends on application-specific protection requirements.

Q: Are there approval differences between substitute parts?

A: Parts 2C4UM and 2D4UM include VDE certification in addition to CSA and UL508. Parts 2E4UM, 2G4UM, and 2Z4UM carry CSA and UL508 approvals. Selection should align with regional regulatory requirements.

Q: Do all substitute parts use identical DIN rail mounting?

A: Yes. All parts are specified for DIN rail mounting with lever actuation and 2-pole configuration. Physical installation is identical across the substitute group.

Q: What is the inventory status for substitute parts?

A: All substitute parts maintain active status with current inventory: 2E4UM (1066 Pcs), 2C4UM (1080 Pcs), 2D4UM (1169 Pcs), 2G4UM (969 Pcs), 2Z4UM (951 Pcs).

Q: Are all parts ROHS3 compliant?

A: Yes. All parts in this substitute group are ROHS3 compliant and REACH unaffected.
