1D60UM 60A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 1D60UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 60A at 480V AC and 24V DC operation. This DIN rail-mounted device is designed for industrial and commercial electrical distribution applications requiring overcurrent and short-circuit protection. The product is currently active in production with full CSA and UL508 certification. Substitute parts may be required due to application voltage requirements, regional availability, or inventory constraints while maintaining equivalent protection characteristics.

Key Parameters

Substitute Part Grouping Explanation

The 1G60UM qualifies as a parametric equivalent substitute based on the following matching criteria:

Identical Parameters:

• Current Rating: 60A
• Breaker Type: Thermal Magnetic
• Series: V-EA
• Mounting Type: DIN Rail
• Actuator Type: Lever
• Number of Poles: 1
• DC Voltage Rating: 24V
• Approval Agency: CSA, UL508
• Product Status: Active
• RoHS Status: ROHS3 Compliant

Differing Parameter:

• AC Voltage Rating: 1D60UM rated 480V AC; 1G60UM rated 277V AC

The substitution is valid when the application circuit operates at 277V AC or lower. The 1G60UM maintains identical thermal-magnetic protection characteristics and mechanical compatibility with the 1D60UM within its specified voltage envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the 1D60UM and 1G60UM are active products with identical CSA and UL508 certifications, ensuring compliance with North American electrical standards. Selection between these parts is determined by the system voltage requirement:

• 1D60UM: Select for applications requiring 480V AC operation or where maximum voltage rating flexibility is needed.
• 1G60UM: Select for applications operating at 277V AC or lower, or where this part number is specified in system documentation.

Both devices provide equivalent 60A thermal-magnetic protection with identical mechanical form factor and DIN rail compatibility. The choice does not affect protection performance within the respective voltage ratings of each device.

Frequently Asked Questions (FAQ)

Q: Can the 1G60UM replace the 1D60UM in a 480V AC circuit?

A: No. The 1G60UM is rated for 277V AC maximum. Using it in a 480V AC circuit exceeds its voltage rating and voids certification. The 1D60UM must be used for 480V AC applications.

Q: Can the 1D60UM replace the 1G60UM in a 277V AC circuit?

A: Yes. The 1D60UM is rated for 480V AC, which exceeds the 277V AC requirement. It provides equivalent protection and is mechanically compatible.

Q: Are the trip characteristics identical between these two models?

A: Yes. Both devices are thermal-magnetic breakers with 60A current rating in the same V-EA series, providing identical overcurrent and short-circuit protection characteristics.

Q: Do both parts have the same DIN rail mounting compatibility?

A: Yes. Both the 1D60UM and 1G60UM mount identically on standard DIN rail systems.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1D60UM and 1G60UM are ROHS3 compliant.

Q: What certifications apply to both parts?

A: Both parts carry CSA and UL508 approvals, meeting North American electrical safety standards for industrial control equipment.
