2C40UM 40A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2C40UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This DIN rail-mounted breaker is designed for 40A applications at 480V AC / 60V DC with lever actuation and 2-pole configuration. The product is active and in stock with full CSA and UL508 approvals. Equivalent substitute parts are available within the same series to accommodate supply chain requirements, inventory management, or specific application needs while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The 2C40UM circuit breaker has three parametric equivalents within the Altech V-EA series: 2B40UM, 2E40UM, and 2G40UM. These parts are direct substitutes based on the following criteria:

Identical Electrical Parameters:

Current Rating: 40A
Voltage Rating - AC: 480V
Voltage Rating - DC: 60V
Breaker Type: Thermal Magnetic

Identical Mechanical Parameters:

Mounting Type: DIN Rail
Actuator Type: Lever
Number of Poles: 2
Series: V-EA

Identical Compliance & Environmental:

Approval Agencies: CSA, UL508
RoHS Status: ROHS3 Compliant
REACH Status: REACH Unaffected
Packaging: Bulk

The substitution logic is based strictly on matching all electrical, mechanical, and compliance parameters. The character designation in the part number (C, B, E, G) represents internal trip characteristic variations within the same electrical and mechanical envelope, allowing interchangeability for the specified application parameters.

Engineering Selection Recommendations

All four parts—2C40UM, 2B40UM, 2E40UM, and 2G40UM—are active products with identical electrical ratings, mechanical specifications, and regulatory approvals. Selection between these equivalents should be based on:

Product Availability: Inventory levels vary across the group. 2G40UM has the highest stock (1028 pcs), followed by 2E40UM (915 pcs), 2B40UM (735 pcs), and 2C40UM (708 pcs).

Compliance Status: All parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across all substitute options.

Certification Alignment: CSA and UL508 approvals are consistent across all parts, supporting direct substitution in certified applications.

Any of these parts can be selected as a direct replacement without modification to circuit design, DIN rail mounting, or system integration parameters.

Frequently Asked Questions (FAQ)

Q: Can 2B40UM, 2E40UM, or 2G40UM be used as direct replacements for 2C40UM?

A: Yes. All four parts share identical electrical ratings (40A, 480V AC, 60V DC), mechanical specifications (DIN rail mounting, 2-pole lever actuation), and regulatory approvals (CSA, UL508). They are parametric equivalents and can be substituted without circuit modification.

Q: What is the difference between the C, B, E, and G character designations?

A: The character designation represents internal trip characteristic variations within the V-EA series. All other electrical and mechanical parameters remain identical across these variants.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four parts—2C40UM, 2B40UM, 2E40UM, and 2G40UM—are ROHS3 compliant and REACH unaffected.

Q: Can these parts be mixed in the same installation?

A: Yes. Since all parts have identical electrical ratings, mechanical mounting, and regulatory approvals, they can be used together in multi-breaker installations without compatibility issues.

Q: What packaging format is available for these parts?

A: All substitute parts are supplied in bulk packaging.

Q: Are there any voltage or current rating differences between these parts?

A: No. All parts are rated for 40A at 480V AC and 60V DC with identical 2-pole configuration and lever actuation.
