2Z32UM 32A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2Z32UM 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. Substitute parts are identified based on identical electrical ratings, mechanical compatibility, and regulatory approvals, enabling direct replacement in applications requiring 32A thermal magnetic protection.

Key Parameters

Parameter	Specification
Manufacturer	Altech Corporation
Series	V-EA
Breaker Type	Thermal Magnetic
Current Rating	32A

Substitute Part Grouping Explanation

Substitution eligibility for the 2Z32UM is determined by strict equivalence across the following parameters:

Current Rating: 32A (exact match required)
Voltage Rating - AC: 480V (exact match required)
Voltage Rating - DC: 60V (exact match required)
Breaker Type: Thermal Magnetic (exact match required)
Mounting Type: DIN Rail (exact match required)
Number of Poles: 2 (exact match required)
Approval Agencies: CSA, UL508 (exact match required)

All substitute parts listed below meet these criteria. The primary distinction among substitute parts is the thermal trip characteristic class (Z, B, C, D, E), which defines the thermal response curve but does not affect electrical or mechanical compatibility within the V-EA series.

Engineering Selection Recommendations

All substitute parts (2B32UM, 2C32UM, 2D32UM, 2E32UM) are active products with identical electrical ratings, mechanical form factors, and regulatory certifications to the 2Z32UM. Selection among these equivalents should be based on application-specific thermal response requirements and inventory availability. All parts maintain ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can 2B32UM, 2C32UM, 2D32UM, and 2E32UM be used interchangeably with 2Z32UM?

A: Yes. All substitute parts share identical electrical ratings (32A, 480V AC, 60V DC), breaker type (thermal magnetic), mounting configuration (DIN rail, 2-pole), and regulatory approvals (CSA, UL508). They are parametric equivalents within the V-EA series.

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

A: These letters denote the thermal trip characteristic class, which defines the thermal response curve of the breaker. The electrical and mechanical specifications remain constant across all classes.

Q: Are all substitute parts currently in stock?

A: Yes. Inventory levels are: 2Z32UM (792 Pcs), 2B32UM (824 Pcs), 2C32UM (823 Pcs), 2D32UM (792 Pcs), 2E32UM (669 Pcs).

Q: Do substitute parts require any modifications to existing installations?

A: No. All substitute parts are mechanically and electrically compatible with existing DIN rail installations designed for the 2Z32UM.

Q: Are all parts RoHS and REACH compliant?

A: Yes. All parts are ROHS3 compliant and REACH unaffected.
