Altech Corporation 2Z3UM 3A Circuit Breaker Z Char2 Equivalent & Substitute Parts

Part Overview

The 2Z3UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 3A at 480V AC and 80V DC. This DIN rail-mounted breaker features a lever actuator and dual-pole configuration. The product is active and in stock with 814 units available. Equivalent substitute parts are necessary when the primary part is unavailable, when procurement lead times require alternative sourcing, or when design flexibility permits selection from the V-EA series family.

Substitute Part Grouping Explanation

The 2Z3UM circuit breaker can be substituted with the following Altech Corporation parts: 2C3UM, 2D3UM, and 2G3UM. All substitute parts maintain identical electrical and mechanical specifications that define interchangeability:

Critical Parameters for Substitution:

• Current Rating: 3A (all substitutes match)
• Voltage Rating - AC: 480V (all substitutes match)
• Voltage Rating - DC: 80V (all substitutes match)
• Breaker Type: Thermal Magnetic (all substitutes match)
• Mounting Type: DIN Rail (all substitutes match)
• Number of Poles: 2 (all substitutes match)
• Actuator Type: Lever (all substitutes match)
• Series: V-EA (all substitutes match)

The substitutes differ only in their character designation (Z, C, D, or G), which reflects internal trip curve characteristics. All parts are manufactured by Altech Corporation, carry ROHS3 compliance, and are rated for the same voltage and current specifications.

Parameter Comparison

Engineering Selection Recommendations

All four circuit breaker models (2Z3UM, 2C3UM, 2D3UM, 2G3UM) are active products with full regulatory compliance. Selection among these substitutes should be based on:

Regulatory Compliance: The 2C3UM and 2D3UM carry additional VDE certification beyond CSA and UL508. If VDE compliance is required for the application, these two models are preferred. The 2Z3UM and 2G3UM meet CSA and UL508 standards.

Availability: The 2D3UM has the highest inventory level at 1007 units, followed by 2G3UM at 835 units, 2Z3UM at 814 units, and 2C3UM at 748 units. Procurement timelines may favor the 2D3UM for immediate availability.

Electrical Characteristics: All models share identical voltage ratings (480V AC, 80V DC) and current rating (3A). The character designation (Z, C, D, G) indicates different trip curve characteristics; selection should align with the specific overcurrent protection requirements of the circuit.

Frequently Asked Questions (FAQ)

Q: Can the 2C3UM, 2D3UM, and 2G3UM be used interchangeably with the 2Z3UM?

A: Yes, these parts are parametric equivalents. All share identical current rating (3A), voltage ratings (480V AC, 80V DC), mounting type (DIN Rail), pole configuration (2-pole), and actuator type (Lever). The character designation reflects internal trip curve characteristics and does not affect mechanical or electrical interchangeability in terms of installation and basic electrical parameters.

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

A: The character designation indicates the trip curve characteristic of the thermal magnetic breaker. These designations define the specific overcurrent response profile. Selection should be based on the circuit protection requirements of the application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all four models (2Z3UM, 2C3UM, 2D3UM, 2G3UM) are ROHS3 compliant.

Q: Do the substitute parts have different regulatory certifications?

A: The 2Z3UM and 2G3UM are certified by CSA and UL508. The 2C3UM and 2D3UM carry additional VDE certification. If VDE compliance is required, the 2C3UM or 2D3UM must be selected.

Q: Are these parts available in different packaging options?

A: All four models are supplied in Bulk packaging as specified in the provided data.

Q: Which substitute part has the best availability?

A: The 2D3UM has the highest inventory at 1007 units in stock.
