3C16UM 16A Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 3C16UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 16A at 480V AC and 80V DC. This DIN rail-mounted device features a lever actuator and three poles, designed for industrial electrical distribution and protection applications. The part is currently active in production with 996 units in stock. Equivalent substitute parts are necessary when the primary part is unavailable, when specific thermal-magnetic characteristics are required for different circuit applications, or when alternative approval certifications are needed for regional compliance.

Substitute Part Grouping Explanation

The substitute parts 3B16UM, 3D16UM, 3E16UM, and 3G16UM are parametric equivalents of the 3C16UM 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
• Number of Poles: 3
• Actuator Type: Lever
• Series: V-EA
• Packaging: Bulk
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Differentiating Factor: The primary distinction among these parts is the thermal-magnetic characteristic designation (C, B, D, E, G), which defines the trip curve and thermal response profile. Each variant maintains identical electrical and mechanical specifications while offering different thermal-magnetic performance characteristics for specific circuit protection requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance. Selection between 3C16UM, 3B16UM, 3D16UM, 3E16UM, and 3G16UM is determined by the required thermal-magnetic characteristic for the specific circuit protection application. The 3C16UM, 3B16UM, and 3D16UM variants carry full CSA, UL508, and VDE certifications, while 3E16UM and 3G16UM carry CSA and UL508 certifications. For applications requiring VDE compliance, selection is limited to 3C16UM, 3B16UM, or 3D16UM. All parts are available in bulk packaging with adequate inventory levels for procurement.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between 3C16UM and its substitute parts? A: The thermal-magnetic characteristic (C, B, D, E, G) defines the trip curve and thermal response profile. All other electrical and mechanical parameters remain identical across the product family.

Q: Can 3B16UM, 3D16UM, 3E16UM, or 3G16UM be used interchangeably with 3C16UM? A: These parts are parametric equivalents with identical current ratings, voltage ratings, mounting specifications, and pole configuration. Interchangeability depends on whether the specific thermal-magnetic characteristic of the substitute part is acceptable for the circuit protection requirements.

Q: Are there certification differences between these substitute parts? A: 3C16UM, 3B16UM, and 3D16UM carry CSA, UL508, and VDE approvals. 3E16UM and 3G16UM carry CSA and UL508 approvals. Applications requiring VDE certification must use 3C16UM, 3B16UM, or 3D16UM.

Q: What is the packaging format for all these parts? A: All parts are supplied in bulk packaging, suitable for industrial procurement and distribution.

Q: Are all substitute parts ROHS3 compliant? A: Yes, all parts in this family are ROHS3 compliant and REACH unaffected.
