3G60UM 60A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 3G60UM is a three-pole thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 60A at 480V AC and 60V DC. This DIN rail-mounted breaker features a lever actuator and is part of the V-EA series. The product is active and holds CSA and UL508 certifications, making it suitable for industrial control applications requiring reliable overcurrent protection.

Equivalent substitute parts are necessary when the primary part is unavailable, when inventory constraints require alternative sourcing, or when application requirements allow for interchangeable thermal magnetic characteristics within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The 3G60UM, 3B60UM, and 3C60UM circuit breakers are parametric equivalents within the Altech V-EA series. Substitution is valid based on the following matching criteria:

• Current Rating: All parts rated at 60A
• Voltage Rating: All parts rated at 480V AC and 60V DC
• Mounting Configuration: All are three-pole DIN rail-mounted breakers
• Actuator Type: All feature lever actuation
• Breaker Technology: All are thermal magnetic type
• Certifications: All hold CSA and UL508 approvals
• Compliance: All are ROHS3 compliant

The primary difference between these parts is the thermal magnetic characteristic designation (G, B, and C), which defines the trip curve behavior. These designations indicate different thermal and magnetic response thresholds suitable for different load profiles and application requirements.

Parameter Comparison

Engineering Selection Recommendations

All three circuit breaker models (3G60UM, 3B60UM, 3C60UM) are active products with identical electrical and mechanical specifications. Selection between these parts should be based on the specific thermal magnetic characteristic requirement for the application:

• All parts maintain active product status with full manufacturer support
• All parts carry CSA and UL508 certifications, ensuring compliance with industrial control standards
• All parts are ROHS3 compliant and meet environmental regulatory requirements
• Inventory availability varies: 3C60UM (1022 pcs), 3G60UM (924 pcs), 3B60UM (751 pcs)

The choice between G, B, and C characteristic designations depends on the connected load type and application requirements. These designations define the trip curve behavior and should be selected based on the specific circuit protection needs.

Frequently Asked Questions (FAQ)

Q: Can 3B60UM be used as a direct replacement for 3G60UM?

A: Yes. Both parts share identical electrical ratings (60A, 480V AC, 60V DC), mounting configuration (DIN rail, three-pole), actuator type (lever), and certifications (CSA, UL508). The difference lies in the thermal magnetic characteristic designation, which affects trip curve behavior.

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

A: These letters indicate the thermal magnetic characteristic of the breaker, defining the trip curve response. The characteristic designation should match the application requirements for proper circuit protection.

Q: Are all three parts compatible with the same DIN rail installation?

A: Yes. All three parts are three-pole DIN rail-mounted breakers with lever actuation and identical mechanical dimensions within the V-EA series.

Q: Do all substitute parts carry the same certifications?

A: Yes. All three parts (3G60UM, 3B60UM, 3C60UM) hold CSA and UL508 approvals and are ROHS3 compliant.

Q: What packaging format is available for these parts?

A: All three parts are supplied in bulk packaging.

Q: Are there any voltage or current rating differences between the substitute parts?

A: No. All three parts are rated identically at 60A, 480V AC, and 60V DC.
