2C16UM 16A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2C16UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 16A at 480V AC / 80V DC with lever actuation and DIN rail mounting. This component is active in production with full inventory availability (1087 units in stock). Substitute parts are identified within the V-EA series where electrical and mechanical parameters remain identical, enabling direct replacement in applications requiring equivalent protection characteristics and form factor compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2C16UM are qualified based on identical electrical and mechanical parameters within the V-EA series. The following criteria determine substitutability:

• Current Rating: 16A (exact match required)
• Voltage Ratings: 480V AC / 80V DC (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 2 (exact match required)
• Series: V-EA (exact match required)

All substitute parts listed below meet these criteria and are therefore electrically and mechanically interchangeable with the 2C16UM.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (2B16UM, 2D16UM, 2G16UM) are active production components with equivalent electrical and mechanical specifications to the 2C16UM. Selection among these interchangeable options may be based on inventory availability and supply chain considerations. The 2C16UM maintains the highest current inventory level at 1087 units. All parts carry ROHS3 compliance and REACH unaffected status. Approval certifications include CSA, UL508, and VDE (with 2G16UM carrying CSA and UL508 certifications).

Frequently Asked Questions (FAQ)

Q: Can 2B16UM, 2D16UM, or 2G16UM be used as direct replacements for 2C16UM?

A: Yes. All substitute parts are parametrically equivalent with identical current ratings (16A), voltage ratings (480V AC / 80V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), actuator type (lever), pole count (2), and series designation (V-EA). Direct substitution is supported without circuit modification.

Q: What distinguishes these part numbers if they are electrically identical?

A: The part numbers reflect different base product designations (2C, 2B, 2D, 2G) within the V-EA series. The suffix "16UM" indicates the 16A rating and packaging configuration. Electrical and mechanical performance remain identical across all variants.

Q: Are there compliance or certification differences between these parts?

A: All parts are ROHS3 compliant and REACH unaffected. Approval agencies include CSA, UL508, and VDE. The 2G16UM carries CSA and UL508 certifications. These certifications support use in industrial control and distribution applications.

Q: How should I select between available substitutes?

A: Selection may be based on inventory availability, lead time, and supply chain logistics. The 2C16UM, 2B16UM, 2D16UM, and 2G16UM are all active production items with adequate stock levels (724–1087 units). No technical differentiation exists for application performance.

Q: Is packaging identical across all substitute parts?

A: Yes. All parts are supplied in bulk packaging configuration, consistent with industrial component distribution standards.
