3C60UM 60A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 3C60UM 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 lever actuation and is certified by CSA and UL508. The product is active and in stock with 1022 units available. Equivalent substitute parts are necessary when the primary model is unavailable, when inventory constraints require alternative sourcing, or when operational requirements allow for interchangeable thermal-magnetic characteristics within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The 3C60UM has two parametric equivalents within the Altech Corporation V-EA series: 3B60UM and 3G60UM. Substitution eligibility is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute parts share identical specifications for current rating (60A), voltage ratings (480V AC / 60V DC), number of poles (3), mounting type (DIN Rail), actuator type (Lever), breaker type (Thermal Magnetic), and regulatory certifications (CSA, UL508). The primary distinction between these models lies in their thermal-magnetic trip characteristics, designated by the letter designation (C, B, and G), which defines the specific current-time response curve. All three parts are manufactured by Altech Corporation, belong to the V-EA series, and maintain ROHS3 compliance and REACH unaffected status. Substitution is valid when the application requirements permit interchangeability of these thermal-magnetic characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three circuit breaker models (3C60UM, 3B60UM, 3G60UM) maintain active product status and are certified by CSA and UL508, confirming compliance with applicable safety and performance standards. Selection between these equivalents should be based on application-specific thermal-magnetic trip curve requirements and current inventory availability. The 3C60UM maintains the highest inventory level at 1022 units. The 3G60UM provides 924 units in stock, and the 3B60UM offers 751 units. All parts are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements. Substitution is valid when the thermal-magnetic characteristic designation (C, B, or G) is interchangeable within the system design parameters.

Frequently Asked Questions (FAQ)

Q: What determines if 3B60UM or 3G60UM can substitute for 3C60UM? A: Substitution is valid when all electrical parameters (60A current rating, 480V AC / 60V DC voltage ratings), mechanical parameters (3-pole, DIN rail mounting, lever actuation), and regulatory certifications (CSA, UL508) are identical. The thermal-magnetic trip characteristic (C, B, or G designation) must be compatible with the application requirements.

Q: Are there any differences in DIN rail compatibility between these three models? A: No. All three models feature identical DIN rail mounting specifications and are mechanically interchangeable on standard DIN rail installations.

Q: Do all three models carry the same regulatory certifications? A: Yes. The 3C60UM, 3B60UM, and 3G60UM are all certified by CSA and UL508, and all maintain ROHS3 compliance and REACH unaffected status.

Q: What is the significance of the letter designation (C, B, G) in the part numbers? A: The letter designation indicates the thermal-magnetic trip characteristic curve of the breaker. This defines the specific current-time response behavior. Substitution between different letter designations is valid only when the application permits interchangeability of these trip characteristics.

Q: Are these parts available in different packaging options? A: All three models are supplied in bulk packaging. No alternative packaging configurations are specified for these part numbers.

Q: Which model should be selected based on current availability? A: The 3C60UM offers the highest inventory at 1022 units. The 3G60UM provides 924 units, and the 3B60UM offers 751 units. Selection should align with project timeline and inventory requirements.
