2E5UM Thermal Magnetic Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The Altech Corporation 2E5UM is a thermal magnetic circuit breaker rated for 5A at 480V AC / 80V DC with lever actuation and DIN rail mounting. This two-pole breaker is designed for industrial control and distribution applications requiring reliable overcurrent protection. The 2E5UM maintains active product status with full CSA and UL508 approvals, ensuring compliance with North American electrical standards. Substitute parts are identified based on identical electrical ratings, mechanical mounting compatibility, and thermal-magnetic trip characteristics within the V-EA series.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2E5UM are qualified based on the following mandatory parameters:

• Current Rating: 5A (identical)
• Voltage Rating - AC: 480V (identical)
• Voltage Rating - DC: 80V (identical)
• Breaker Type: Thermal Magnetic (identical)
• Mounting Type: DIN Rail (identical)
• Actuator Type: Lever (identical)
• Number of Poles: 2 (identical)
• Series: V-EA (identical)
• Manufacturer: Altech Corporation (identical)

The primary distinction among substitute parts is the thermal trip characteristic class (B, C, D, E, or G), which defines the current threshold at which the thermal element activates. All qualified substitutes maintain identical electrical and mechanical specifications, allowing direct replacement within applications where the specific trip characteristic is compatible with circuit protection requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and carry CSA and UL508 certifications, meeting North American electrical safety standards. Parts 2C5UM and 2D5UM provide additional VDE approval for European market compliance. Selection among these substitutes is determined solely by the required thermal trip characteristic class for the specific application circuit protection scheme. Electrical and mechanical compatibility is assured across all listed alternatives.

Frequently Asked Questions (FAQ)

Q: Can 2E5UM be replaced with 2B5UM, 2C5UM, 2D5UM, or 2G5UM?

A: Yes. All substitute parts share identical current rating (5A), voltage ratings (480V AC / 80V DC), mounting type (DIN Rail), pole configuration (2-pole), and actuator type (Lever). Substitution is valid when the thermal trip characteristic of the replacement part is compatible with the circuit protection requirements.

Q: What is the difference between the trip characteristics (B, C, D, E, G)?

A: Trip characteristic class defines the thermal element activation threshold. The specific class required depends on the application's inrush current tolerance and protection sensitivity. All classes are available within the V-EA series at identical electrical ratings.

Q: Are all substitutes approved for the same applications?

A: All substitutes carry CSA and UL508 approvals. Parts 2C5UM and 2D5UM include additional VDE certification. Approval compatibility is assured for North American applications; European applications may benefit from VDE-certified alternatives.

Q: Is DIN rail mounting identical across all parts?

A: Yes. All listed parts use DIN rail mounting with identical mechanical specifications, ensuring direct physical compatibility in existing installations.

Q: What is the inventory status for each substitute?

A: Current stock levels are: 2E5UM (1033 Pcs), 2B5UM (1102 Pcs), 2C5UM (983 Pcs), 2D5UM (850 Pcs), 2G5UM (1039 Pcs). All parts are available as new original stock.
