2D32UM 32A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2D32UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 32A at 480V AC and 60V DC. This DIN rail-mounted breaker is part of the V-EA series and maintains active product status with full CSA and UL508 certification. Equivalent substitute parts are available within the same series to accommodate supply chain flexibility, inventory optimization, and application-specific requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts for the 2D32UM maintain identical electrical and mechanical parameters as defined by the core specifications: 32A current rating, 480V AC / 60V DC voltage ratings, thermal magnetic breaker type, 2-pole configuration, lever actuator, and DIN rail mounting. The substitutes differ only in their characteristic curve designation (B, C, D, or E), which represents the trip point sensitivity of the thermal magnetic mechanism. This designation does not alter the fundamental electrical ratings or physical compatibility but allows selection based on specific load characteristics and application requirements.

The following parts are parametric equivalents:

• 2B32UM (B characteristic)
• 2C32UM (C characteristic)
• 2E32UM (E characteristic)

All parts share identical voltage ratings, current capacity, mounting interface, and regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

All four part numbers (2D32UM, 2B32UM, 2C32UM, 2E32UM) are active products with identical electrical ratings and mechanical specifications. Selection between these equivalents is based on characteristic curve requirements specific to the application load profile. All parts maintain ROHS3 compliance, REACH unaffected status, and dual certification under CSA and UL508 standards. Inventory availability ranges from 669 to 824 pieces across the substitute group, supporting supply chain continuity. Part selection should be determined by the required trip characteristic curve (B, C, D, or E) for the specific circuit protection application.

Frequently Asked Questions (FAQ)

Q: Can 2B32UM, 2C32UM, and 2E32UM be used interchangeably with 2D32UM?

A: Yes, these parts are parametric equivalents with identical electrical ratings (32A, 480V AC, 60V DC), mechanical mounting (DIN rail, 2-pole, lever actuator), and certifications (CSA, UL508). The letter designation (B, C, D, E) indicates the characteristic curve only and does not affect voltage or current ratings.

Q: What is the difference between the B, C, D, and E characteristic designations?

A: The characteristic letter represents the trip point sensitivity of the thermal magnetic mechanism. Selection depends on the specific load characteristics and protection requirements of the circuit application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all four part numbers (2D32UM, 2B32UM, 2C32UM, 2E32UM) are ROHS3 compliant and REACH unaffected.

Q: Do all substitute parts have the same physical dimensions and DIN rail compatibility?

A: Yes, all parts are mounted on DIN rail with identical mechanical specifications and physical compatibility.

Q: What certifications apply to these circuit breakers?

A: All parts carry CSA and UL508 certifications, meeting North American industrial control standards.

Q: Is packaging identical across all substitute parts?

A: All parts are supplied in bulk packaging as specified by Altech Corporation.
