Altech Corporation 3G32UM 32A Thermal Magnetic Circuit Breaker

Part Overview

The 3G32UM is a 32-ampere thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This DIN rail-mounted breaker is designed for 480 V AC and 60 V DC applications with lever actuation and three-pole configuration. The product maintains active status with full CSA and UL508 approval certifications. Equivalent substitute parts exist within the same series that share identical electrical and mechanical specifications, differing only in thermal characteristic classification (C, D, E, and Z designations). Substitute parts become necessary when specific thermal response requirements or inventory availability necessitate alternative characteristic ratings.

Substitute Part Grouping Explanation

The 3G32UM circuit breaker has four parametric equivalent substitutes: 3C32UM, 3D32UM, 3E32UM, and 3Z32UM. All five part numbers share identical electrical and mechanical parameters that define circuit breaker functionality and compatibility:

Current Rating: 32A (identical across all variants)
Voltage Ratings: 480 V AC and 60 V DC (identical across all variants)
Mounting Configuration: DIN Rail, 3-pole, lever-actuated (identical across all variants)
Breaker Technology: Thermal Magnetic (identical across all variants)
Certifications: CSA and UL508 approval (identical across all variants)
Compliance: ROHS3 Compliant, REACH Unaffected (identical across all variants)

The substitution basis is the thermal characteristic classification embedded in each part number designation (G, C, D, E, Z). These designations define the thermal response curve of the breaker but do not alter the core electrical specifications, mounting interface, or approval status. Parts are interchangeable when thermal characteristic requirements permit selection from the available options.

Engineering Selection Recommendations

All five circuit breaker variants maintain active product status and carry identical CSA and UL508 certifications, confirming compliance with North American electrical standards. Each part is ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements. Selection among 3G32UM, 3C32UM, 3D32UM, 3E32UM, and 3Z32UM depends on application-specific thermal characteristic requirements. The thermal classification (G, C, D, E, Z) determines the trip curve response to overload conditions and must align with circuit protection requirements. All variants are mechanically and electrically interchangeable on DIN rail installations rated for 480 V AC and 60 V DC operation with 32-ampere load protection.

Frequently Asked Questions (FAQ)

Q: Are the 3G32UM and its substitute parts physically interchangeable on DIN rail?

A: Yes. All five variants share identical DIN rail mounting specifications, three-pole configuration, and lever actuation. Physical installation requires no modification.

Q: What determines whether I can substitute one part number for another?

A: Substitution is valid when the thermal characteristic classification of the replacement part meets the circuit protection requirements of the application. All five variants provide identical 32-ampere protection at 480 V AC and 60 V DC, differing only in thermal response curve.

Q: Do all substitute parts carry the same certifications?

A: Yes. All five part numbers—3G32UM, 3C32UM, 3D32UM, 3E32UM, and 3Z32UM—hold CSA and UL508 approval and are ROHS3 compliant.

Q: Can I use these breakers in both AC and DC circuits?

A: Yes. All variants are rated for 480 V AC and 60 V DC operation, permitting use in either application within these voltage limits.

Q: What is the difference between the G, C, D, E, and Z designations?

A: These letters represent thermal characteristic classifications that define the trip curve response to overload conditions. The specific thermal response curve must align with the circuit protection strategy required by the application.

Q: Are all substitute parts available in the same packaging?

A: Yes. All five variants are supplied in bulk packaging.
