2C1.6UM Circuit Breaker Equivalent & Substitute Parts

Part Overview

The 2C1.6UM is a thermal magnetic circuit breaker manufactured by Altech Corporation, rated for 1.6A at 480V AC and 80V DC. This DIN rail-mounted device features a lever actuator and dual-pole configuration, designed for industrial control and protection applications. The part maintains active product status with full compliance to CSA, UL508, and VDE standards. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number is unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2C1.6UM are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain constant:

• Current Rating: 1.6A
• 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
• Approval Agencies: CSA, UL508, VDE (minimum requirement)

All identified substitute parts maintain identical electrical ratings, mechanical configuration, and mounting specifications. Differences in part number designation reflect internal manufacturer coding variations within the same product family and do not affect functional compatibility or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2C1.6UM, 2D1.6UM, and 2Z1.6UM—are functionally equivalent and maintain active product status. Selection between these parts should be based on availability and compliance requirements specific to the application.

The 2C1.6UM and 2D1.6UM both carry full certification from CSA, UL508, and VDE, providing the broadest regulatory coverage. The 2Z1.6UM carries CSA and UL508 certification, meeting North American and UL-specific requirements but lacking VDE certification for European applications.

For applications requiring VDE compliance, either 2C1.6UM or 2D1.6UM is appropriate. For North American applications where VDE certification is not mandated, 2Z1.6UM is a valid substitute. All parts are ROHS3 compliant and suitable for industrial control environments.

Frequently Asked Questions (FAQ)

Q: Can 2D1.6UM be used as a direct replacement for 2C1.6UM?

A: Yes. Both parts are parametrically equivalent across all electrical ratings (1.6A, 480V AC, 80V DC), mechanical configuration (2-pole, lever actuator, DIN rail mount), and regulatory certifications (CSA, UL508, VDE). No circuit modifications or reconfiguration is required.

Q: What is the difference between 2C1.6UM and 2Z1.6UM?

A: The electrical and mechanical specifications are identical. The primary difference is regulatory certification: 2C1.6UM includes VDE approval, while 2Z1.6UM does not. For applications requiring European compliance, 2C1.6UM is the appropriate choice. For North American applications, both are acceptable.

Q: Are all three parts available in the same packaging?

A: Yes. All three parts are supplied in bulk packaging as standard. Packaging format does not differ between part numbers.

Q: Can these parts be mixed in the same installation?

A: Yes. Since all three parts are parametrically equivalent and carry the required certifications for the application, they can be used interchangeably within the same circuit or control panel without affecting performance or safety.

Q: Which part should I specify for new designs?

A: Specify based on regulatory requirements. For applications requiring full international compliance (North America and Europe), specify 2C1.6UM or 2D1.6UM. For North American-only applications, any of the three parts is acceptable. Consult application-specific compliance documentation to confirm certification requirements.
