Key Parameters

Substitute Part Grouping Explanation

The 1C32UM qualifies as a parametric equivalent to the 1D32UM based on the following matching specifications:

• Current Rating: 32A (identical)
• Voltage Rating - AC: 480V (identical)
• Voltage Rating - DC: 24V (identical)
• Breaker Type: Thermal Magnetic (identical)
• Mounting Type: DIN Rail (identical)
• Number of Poles: 1 (identical)
• Actuator Type: Lever (identical)
• Approval Agency: CSA, UL508 (identical)
• Series: V-EA (identical)
• RoHS Status: ROHS3 Compliant (identical)

Both parts belong to the Altech Corporation V-EA series and maintain identical electrical and mechanical characteristics. The primary distinction is the base product designation (1D32 versus 1C32), which reflects internal product line differentiation within the same functional class.

Parameter Comparison

Engineering Selection Recommendations

Both the 1D32UM and 1C32UM are active products with full regulatory compliance under CSA and UL508 standards. Selection between these parts should be based on availability and procurement lead times. The 1C32UM currently maintains higher inventory levels (905 units versus 689 units), which may provide supply chain advantages. Both parts carry identical ROHS3 compliance and are suitable for direct substitution in 32A, 480V AC / 24V DC DIN rail applications requiring thermal magnetic protection.

Frequently Asked Questions (FAQ)

Q: Can the 1C32UM directly replace the 1D32UM in existing installations?

A: Yes. Both parts share identical electrical ratings (32A, 480V AC, 24V DC), mechanical specifications (DIN rail mounting, single-pole, lever actuator), and regulatory approvals (CSA, UL508). Direct substitution is supported.

Q: What is the difference between the 1D32UM and 1C32UM?

A: The parts differ only in their base product designation (1D32 versus 1C32). All functional parameters, electrical ratings, mechanical characteristics, and certifications are identical. Both belong to the Altech V-EA series.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the 1D32UM and 1C32UM are ROHS3 compliant and meet environmental regulatory requirements.

Q: Which part should I select based on availability?

A: The 1C32UM currently has higher inventory availability (905 units in stock) compared to the 1D32UM (689 units in stock). Selection may depend on procurement timelines and supply requirements.

Q: Do both parts carry the same regulatory approvals?

A: Yes. Both parts are certified by CSA and UL508, ensuring compliance with North American industrial control standards.
