3C1UM Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 3C1UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 1A at 480V AC / 80V DC with a 3-pole lever-actuated design for DIN rail mounting. This component is Active in product status and maintains full compliance with CSA, UL508, and VDE approval standards. Substitute parts are identified when inventory constraints, lead time requirements, or supply chain disruptions necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The 3D1UM qualifies as a parametric equivalent to the 3C1UM based on matching electrical and mechanical specifications. Substitution eligibility is determined by the following criteria:

• Current Rating: 1A (identical)
• Voltage Rating - AC: 480V (identical)
• Voltage Rating - DC: 80V (identical)
• Breaker Type: Thermal Magnetic (identical)
• Number of Poles: 3 (identical)
• Actuator Type: Lever (identical)
• Mounting Type: DIN Rail (identical)
• Series: V-EA (identical)
• Approval Agencies: CSA, UL508, VDE (identical)
• RoHS Status: ROHS3 Compliant (identical)

Both parts are manufactured by Altech Corporation and maintain Active product status. The difference in base product number (3C vs. 3D) reflects internal product line designation but does not affect functional equivalence within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 3C1UM and 3D1UM are suitable for direct substitution in applications requiring a 1A, 3-pole thermal magnetic circuit breaker rated for 480V AC / 80V DC operation on DIN rail systems. Selection between these parts should be based on availability and lead time requirements, as all electrical and mechanical parameters are identical. Both parts maintain Active product status and carry equivalent regulatory approvals (CSA, UL508, VDE) with ROHS3 compliance. No functional or performance differences exist between these components within the specified parameter set.

Frequently Asked Questions (FAQ)

Q: Can the 3D1UM replace the 3C1UM in an existing installation?

A: Yes. The 3D1UM is a parametric equivalent with identical current rating (1A), voltage ratings (480V AC / 80V DC), pole configuration (3-pole), actuator type (lever), mounting interface (DIN rail), and regulatory approvals. Direct substitution is permissible.

Q: What is the difference between the 3C1UM and 3D1UM?

A: The base product numbers (3C vs. 3D) reflect internal Altech Corporation product line designations. All specified electrical and mechanical parameters are identical, and both parts are manufactured to the same V-EA series specifications.

Q: Are both parts currently available?

A: Both parts maintain Active product status. The 3C1UM has 1122 pieces in stock, and the 3D1UM has 828 pieces in stock. Availability should be confirmed with the supplier for current lead times.

Q: Do these parts have the same regulatory approvals?

A: Yes. Both the 3C1UM and 3D1UM carry identical approvals: CSA, UL508, and VDE. Both are ROHS3 compliant and REACH unaffected.

Q: Can I use these parts interchangeably in new designs?

A: Yes. Since all electrical and mechanical parameters match, either part number can be specified for new designs. Selection should be based on supplier availability and lead time.
