2G63UM 63A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2G63UM 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 a lever actuator and is UL508 approved. The product is active and currently in stock with 673 units available. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product series and approval standards.

Key Parameters

Substitute Part Grouping Explanation

The 2C63UM qualifies as a parametric equivalent to the 2G63UM based on the following criteria:

• Identical current rating of 63A
• Identical AC voltage rating of 480V and DC voltage rating of 60V
• Identical breaker type: thermal magnetic
• Identical mounting configuration: DIN rail with lever actuator
• Identical pole configuration: 2 poles
• Same series designation: V-EA
• Same approval standard: UL508
• Same RoHS3 compliance status
• Same REACH unaffected status

The primary distinction between these parts is the trip characteristic designation: the 2G63UM carries a G characteristic while the 2C63UM carries a C characteristic. Both are members of the same V-EA series and maintain full electrical and mechanical compatibility within their respective characteristic classifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 2G63UM and 2C63UM are active products with full UL508 approval and ROHS3 compliance. Selection between these parts should be based on the specific trip characteristic requirement of the application. The G characteristic of the 2G63UM and the C characteristic of the 2C63UM represent different thermal-magnetic response profiles suited to different load types. Both parts maintain identical electrical ratings, mechanical mounting, and regulatory compliance. Inventory availability shows 792 units of the 2C63UM against 673 units of the 2G63UM.

Frequently Asked Questions (FAQ)

Q: Can the 2C63UM directly replace the 2G63UM in an existing installation?

A: Both parts share identical electrical ratings (63A, 480V AC, 60V DC), mounting type (DIN rail), actuator configuration (lever), and pole count (2). The difference lies in trip characteristic designation. Substitution is permissible only if the application requirements allow for the C characteristic response instead of the G characteristic response.

Q: What is the significance of the G and C characteristic designations?

A: These designations define the thermal-magnetic trip curve behavior. The characteristic determines the current threshold and time response for breaker activation under fault conditions. Application requirements dictate which characteristic is appropriate.

Q: Are both parts UL508 approved?

A: Yes. Both the 2G63UM 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 compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected.
