3C32UM 32A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 3C32UM is a three-pole thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 32A at 480V AC and 60V DC. This DIN rail-mounted breaker is part of the V-EA series and maintains Active product status with full CSA and UL508 certification. Substitute parts are identified based on identical electrical ratings, mechanical specifications, and approval certifications to ensure direct interchangeability in DIN rail installations.

Substitute Part Grouping Explanation

The 3C32UM has three parametric equivalents within the V-EA series: 3D32UM, 3E32UM, and 3Z32UM. Substitution is valid based on the following criteria:

Identical Parameters Across All Equivalents:

• Current Rating: 32A
• Voltage Rating - AC: 480V
• Voltage Rating - DC: 60V
• Number of Poles: 3
• Breaker Type: Thermal Magnetic
• Mounting Type: DIN Rail
• Actuator Type: Lever
• Approval Agencies: CSA, UL508
• Series: V-EA
• RoHS Status: ROHS3 Compliant

The substitutes differ only in their base product designation (C, D, E, Z character variants), which reflects internal Altech Corporation product line differentiation. All four part numbers share identical electrical and mechanical specifications, making them direct substitutes for DIN rail circuit breaker applications.

Parameter Comparison

Engineering Selection Recommendations

All four part numbers (3C32UM, 3D32UM, 3E32UM, 3Z32UM) are Active products with identical electrical specifications and dual certification (CSA and UL508). Selection between these equivalents should be based on:

1. Availability: Inventory levels vary across the four variants. 3D32UM has the highest stock (1108 Pcs), followed by 3Z32UM (1063 Pcs), 3C32UM (1032 Pcs), and 3E32UM (808 Pcs).

2. Compliance Requirements: All variants maintain ROHS3 compliance and REACH Unaffected status, meeting current environmental regulations.

3. Certification Alignment: CSA and UL508 certifications are uniform across all substitutes, ensuring compliance with North American electrical standards.

4. DIN Rail Compatibility: All variants are designed for identical DIN rail mounting with lever actuation, ensuring mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can 3D32UM, 3E32UM, and 3Z32UM be used interchangeably with 3C32UM?

A: Yes. All four part numbers share identical electrical ratings (32A, 480V AC, 60V DC), mechanical specifications (3-pole, DIN rail mount, lever actuator), and certifications (CSA, UL508). They are direct parametric equivalents.

Q: What determines substitutability for these circuit breakers?

A: Substitutability is determined by matching current rating, voltage ratings (both AC and DC), number of poles, breaker type (thermal magnetic), mounting type (DIN rail), and approval certifications. All four variants meet these criteria identically.

Q: Are there any differences in performance between the C, D, E, and Z variants?

A: The C, D, E, and Z designations represent internal product line variants within Altech Corporation's V-EA series. No performance differences exist in the electrical or mechanical specifications provided.

Q: Which variant should I select based on availability?

A: Selection should be based on your supply chain requirements. 3D32UM offers the highest current inventory (1108 Pcs), while all variants maintain adequate stock levels for standard procurement.

Q: Are all variants RoHS and REACH compliant?

A: Yes. All four part numbers are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Can these breakers be used in both AC and DC applications?

A: Yes. All variants are rated for 480V AC and 60V DC operation, supporting both AC and DC circuit protection applications.
