Key Parameters

Substitute Part Grouping Explanation

The 2C63UM qualifies as a parametric equivalent to the 2B63UM based on the following matching specifications:

• Current Rating: 63A (identical)
• Voltage Rating - AC: 480V (identical)
• Voltage Rating - DC: 60V (identical)
• Breaker Type: Thermal Magnetic (identical)
• Mounting Type: DIN Rail (identical)
• Actuator Type: Lever (identical)
• Number of Poles: 2 (identical)
• Approval Agency: UL508 (identical)
• Series: V-EA (identical)
• RoHS Status: ROHS3 Compliant (identical)
• REACH Status: REACH Unaffected (identical)

The primary distinction between these parts is the thermal characteristic rating: the 2B63UM carries a B characteristic, while the 2C63UM carries a C characteristic. Both are manufactured by Altech Corporation and maintain identical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 2B63UM and 2C63UM are active products with full regulatory compliance. Selection between these parts should be based on the specific thermal characteristic requirement of the application. The B characteristic (2B63UM) and C characteristic (2C63UM) define the trip current thresholds and response times under overload conditions. Both parts maintain identical electrical ratings, mechanical mounting specifications, and UL508 approval status. Inventory availability is comparable for both options, with 821 units of the 2B63UM and 792 units of the 2C63UM currently in stock.

Frequently Asked Questions (FAQ)

Q: What is the difference between the 2B63UM and 2C63UM? A: The primary difference is the thermal characteristic rating. The 2B63UM features a B characteristic, while the 2C63UM features a C characteristic. All other electrical and mechanical parameters are identical.

Q: Can the 2C63UM be used as a direct replacement for the 2B63UM? A: The 2C63UM is a parametric equivalent with matching voltage ratings, current ratings, mounting type, and regulatory approvals. Substitution is valid when the application permits the use of a C characteristic breaker in place of a B characteristic breaker.

Q: Are both parts UL508 approved? A: Yes, both the 2B63UM and 2C63UM carry UL508 approval and are ROHS3 compliant.

Q: What is the packaging format for these parts? A: Both parts are supplied in bulk packaging.

Q: Are there any REACH or RoHS restrictions on these parts? A: Both parts are ROHS3 compliant and REACH unaffected, indicating full compliance with current environmental regulations.
