2E63UM Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The 2E63UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 63A at 480V AC and 60V DC. This DIN rail-mounted breaker features an E-characteristic trip curve and lever actuator, designed for industrial electrical distribution applications. The product is active and widely available in inventory (968 pcs in stock). Substitute parts are identified based on matching electrical ratings, mechanical compatibility, and approval certifications to ensure direct interchangeability in existing installations.

Key Parameters

Substitute Part Grouping Explanation

The 2C63UM qualifies as a parametric equivalent to the 2E63UM based on the following matching criteria:

• 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)

The primary distinction between these parts is the trip characteristic curve: the 2E63UM features an E-characteristic curve, while the 2C63UM features a C-characteristic curve. Both are manufactured by Altech Corporation and share identical electrical and mechanical specifications, allowing substitution where the trip characteristic difference is acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

Both the 2E63UM and 2C63UM are active products with UL508 approval and ROHS3 compliance. Selection between these parts depends on the required trip characteristic curve for the specific application. The E-characteristic curve of the 2E63UM provides faster response to overload conditions compared to the C-characteristic curve of the 2C63UM. Both parts are manufactured by Altech Corporation within the V-EA series and maintain identical electrical and mechanical specifications, ensuring mechanical and electrical interchangeability when trip curve requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can the 2C63UM directly replace the 2E63UM in an existing installation?

A: The 2C63UM is mechanically and electrically compatible with the 2E63UM, sharing identical current ratings, voltage ratings, mounting type, and pole configuration. The primary difference is the trip characteristic curve (C-characteristic versus E-characteristic). Direct replacement is possible only if the application permits the use of a C-characteristic curve instead of an E-characteristic curve.

Q: What is the significance of the trip characteristic designation (E versus C)?

A: The trip characteristic designates the thermal-magnetic response curve of the breaker. The E-characteristic provides faster response to overload conditions, while the C-characteristic provides a more moderate response. Selection depends on the specific load characteristics and protection requirements of the circuit.

Q: Are both parts available in the same packaging format?

A: Yes, both the 2E63UM and 2C63UM are supplied in bulk packaging and are designed for DIN rail mounting with identical mechanical dimensions and installation procedures.

Q: Do both parts carry the same regulatory approvals?

A: Yes, both parts are UL508 approved and ROHS3 compliant, meeting identical regulatory and environmental standards.

Q: What is the inventory status for each part?

A: The 2E63UM has 968 pieces in stock, while the 2C63UM has 792 pieces in stock, both listed as new original inventory.
