3E16UM 16A Circuit Breaker Equivalent & Substitute Parts
Part Overview
The 3E16UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 16A at 480V AC and 80V DC. This DIN rail-mounted breaker features a lever actuator and three-pole configuration, designed for industrial control and distribution applications. The part is currently active in production with 1,036 units in stock. Equivalent substitute parts are necessary to ensure supply chain continuity, accommodate regional certification requirements, or address specific application characteristics such as trip curve differentiation.

Substitute Part Grouping Explanation
The 3E16UM is substitutable with three equivalent parts within the Altech V-EA series: 3B16UM, 3D16UM, and 3G16UM. All substitute parts share identical electrical and mechanical specifications with the main part:
- Current Rating: 16A
- Voltage Rating: 480V AC / 80V DC
- Breaker Type: Thermal Magnetic
- Number of Poles: 3
- Mounting Type: DIN Rail
- Actuator Type: Lever
- Series: V-EA
- RoHS Compliance: ROHS3 Compliant
- Packaging: Bulk
The primary differentiation among these parts lies in their trip curve characteristics, designated by the letter suffix (E, B, D, G). These designations define the thermal-magnetic response curve and are the only functional distinction between otherwise identical breakers. All parts maintain the same physical form factor, electrical ratings, and certifications, enabling direct substitution based on application-specific trip curve requirements.

Engineering Selection Recommendations
All four parts (3E16UM, 3B16UM, 3D16UM, 3G16UM) are active products with full regulatory compliance. Selection between these equivalents should be based on trip curve requirements specific to the application:
- 3E16UM: E-curve characteristic
- 3B16UM: B-curve characteristic (includes additional VDE certification)
- 3D16UM: D-curve characteristic (includes additional VDE certification)
- 3G16UM: G-curve characteristic
All parts carry CSA and UL508 certifications. The 3B16UM and 3D16UM variants include VDE certification, providing additional compliance for European applications. Inventory levels are comparable across all variants, ranging from 954 to 1,104 units in stock.
Frequently Asked Questions (FAQ)
Q: Can 3B16UM, 3D16UM, and 3G16UM be used interchangeably with 3E16UM?
A: These parts are electrically and mechanically equivalent and share identical electrical ratings, voltage specifications, and physical form factors. They differ only in trip curve characteristics. Interchangeability depends on whether the application requires a specific trip curve. Verify the trip curve requirement in your circuit design before substitution.
Q: What is the difference between the E, B, D, and G designations?
A: These letters designate the thermal-magnetic trip curve of the breaker, which defines the response time and current threshold at which the breaker trips. Each curve is optimized for different load types and protection requirements. Consult application specifications to determine which curve is required.
Q: Are all substitute parts ROHS3 compliant?
A: Yes, all four parts (3E16UM, 3B16UM, 3D16UM, 3G16UM) are ROHS3 compliant.
Q: Do the substitute parts have the same certifications as the 3E16UM?
A: All parts carry CSA and UL508 certifications. The 3B16UM and 3D16UM additionally carry VDE certification. If VDE certification is required for your application, select 3B16UM or 3D16UM.
Q: Are these parts available in different packaging options?
A: All listed parts are supplied in bulk packaging. No alternative packaging configurations are specified in the product data.
Q: What is the current inventory status for each part?
A: 3E16UM: 1,036 units; 3B16UM: 954 units; 3D16UM: 1,104 units; 3G16UM: 1,057 units. All parts are in stock as new original components.
