2B32UM 32A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2B32UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This DIN rail-mounted breaker is designed for 32A applications at 480V AC and 60V DC with lever actuation and dual-pole configuration. The product is currently active and available in bulk packaging with 824 units in stock. Substitute parts are necessary to address supply chain flexibility, inventory optimization, and application-specific thermal magnetic characteristic requirements within the same electrical and mechanical parameter envelope.

Substitute Part Grouping Explanation

The substitute parts 2C32UM, 2D32UM, and 2E32UM are parametric equivalents to the 2B32UM based on identical electrical and mechanical specifications. All four parts share the following critical parameters that define substitutability:

Current Rating: 32A
Voltage Rating: 480V AC / 60V DC
Breaker Type: Thermal Magnetic
Mounting: DIN Rail
Poles: 2
Actuator: Lever
Approvals: CSA, UL508
Series: V-EA
RoHS Compliance: ROHS3

The designation suffix (B, C, D, E) indicates different thermal magnetic characteristic curves within the same product family. These variants allow selection based on specific load characteristics and trip curve requirements while maintaining full electrical and mechanical compatibility.

Engineering Selection Recommendations

All substitute parts (2C32UM, 2D32UM, 2E32UM) are active products with current manufacturing status and full compliance with CSA and UL508 certifications. All variants maintain ROHS3 compliance and are available in bulk packaging. Selection between 2B32UM and its substitutes should be based on thermal magnetic characteristic curve requirements specific to the application load profile. Inventory availability ranges from 669 to 824 units across all four variants, supporting supply chain continuity.

Frequently Asked Questions (FAQ)

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

A: Yes, within the constraint that the thermal magnetic characteristic curve (B, C, D, or E designation) matches the application requirement. All four parts are electrically and mechanically identical at 32A, 480V AC, 60V DC with DIN rail mounting and dual-pole lever actuation.

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

A: The suffix letter indicates the thermal magnetic trip characteristic curve. Each variant provides different response times to overcurrent conditions while maintaining the same rated current and voltage specifications.

Q: Are all substitute parts CSA and UL508 certified?

A: Yes. All four parts (2B32UM, 2C32UM, 2D32UM, 2E32UM) carry identical CSA and UL508 approvals.

Q: Do the substitute parts have the same DIN rail mounting footprint?

A: Yes. All parts are DIN rail-mounted with identical mechanical specifications and mounting compatibility.

Q: Are all variants ROHS3 compliant?

A: Yes. All four parts meet ROHS3 compliance requirements.
