2B16UM 16A Circuit Breaker Equivalent & Substitute Parts
Part Overview
The 2B16UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, part of the V-EA series. This DIN rail-mounted breaker is rated for 16A at 480V AC and 80V DC with a lever actuator and two poles. The product is active and in stock with 1,011 units available. Circuit breakers of this specification are essential components in electrical distribution systems, and equivalent substitute parts may be required due to inventory availability, supply chain considerations, or specific application requirements within the same electrical parameters.

Substitute Part Grouping Explanation
The 2B16UM has three parametric equivalent substitutes within the Altech Corporation V-EA series: 2C16UM, 2D16UM, and 2G16UM. These parts are classified as equivalent substitutes based on the following criteria:
Matching Parameters (Substitution Basis):
- Current Rating: 16A
- Voltage Rating - AC: 480V
- Voltage Rating - DC: 80V
- Breaker Type: Thermal Magnetic
- Mounting Type: DIN Rail
- Actuator Type: Lever
- Number of Poles: 2
- Series: V-EA
- Packaging: Bulk
- RoHS Status: ROHS3 Compliant
All substitute parts maintain identical electrical and mechanical specifications, allowing them to function interchangeably in applications requiring 16A thermal magnetic circuit breakers with the specified voltage ratings and DIN rail mounting configuration.

Engineering Selection Recommendations
All four parts—2B16UM, 2C16UM, 2D16UM, and 2G16UM—are active products with ROHS3 compliance and carry regulatory approvals from major certification bodies. The 2B16UM, 2C16UM, and 2D16UM hold full approval from CSA, UL508, and VDE. The 2G16UM carries CSA and UL508 approval. Selection between these equivalent parts should be based on inventory availability and application-specific certification requirements. All parts are suitable for direct substitution in applications requiring 16A thermal magnetic circuit breakers with 480V AC and 80V DC ratings on DIN rail installations.
Frequently Asked Questions (FAQ)
Q: Can 2C16UM, 2D16UM, and 2G16UM be used as direct replacements for 2B16UM?
A: Yes. All three parts are parametric equivalents with identical electrical ratings (16A, 480V AC, 80V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), and mechanical specifications (lever actuator, 2 poles). They are interchangeable in applications requiring these specifications.
Q: What are the key parameters that define substitution eligibility?
A: Substitution is based on matching current rating (16A), AC voltage (480V), DC voltage (80V), breaker type (thermal magnetic), mounting type (DIN rail), actuator type (lever), and pole count (2). All substitute parts maintain these parameters identically.
Q: Are there differences in regulatory approvals between these parts?
A: The 2B16UM, 2C16UM, and 2D16UM carry CSA, UL508, and VDE approvals. The 2G16UM carries CSA and UL508 approvals. Applications requiring VDE certification should specify 2B16UM, 2C16UM, or 2D16UM.
Q: Does packaging differ between these parts?
A: No. All parts are supplied in bulk packaging.
Q: Are all parts RoHS compliant?
A: Yes. All four parts are ROHS3 compliant.
Q: Which part has the highest current inventory?
A: The 2C16UM has the highest inventory at 1,087 pieces, followed by 2B16UM at 1,011 pieces, 2D16UM at 783 pieces, and 2G16UM at 724 pieces.
