Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 2800878 are identified based on strict parametric equivalence within the CB series. The following electrical and mechanical parameters must remain constant for substitution validity:

• Current Rating: 16A
• Voltage Rating - AC: 277V
• Voltage Rating - DC: 80V
• Breaker Type: Thermal Magnetic
• Actuator Type: Slide Switch
• Number of Poles: 2
• Mounting Type: Holder
• Series: CB

Parts 2800889 and 2800900 meet all substitution criteria. Both maintain identical electrical specifications and mechanical configuration, differing only in RoHS certification status (RoHS Compliant vs. ROHS3 Compliant), which does not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2800878, 2800889, and 2800900—are Active status components from Phoenix Contact's CB series and are suitable for direct substitution based on electrical and mechanical equivalence. Selection between these parts should be based on:

1. Regulatory Compliance Requirements: Part 2800878 and 2800900 carry ROHS3 Compliant status. Part 2800889 carries RoHS Compliant status. Applications requiring ROHS3 certification should specify 2800878 or 2800900.

2. REACH Compliance: Parts 2800878 and 2800900 are REACH Unaffected. Part 2800889 does not specify REACH status. Applications subject to REACH regulations should prioritize 2800878 or 2800900.

3. Inventory Availability: Part 2800878 has the highest inventory level at 1145 pieces, followed by 2800889 at 961 pieces and 2800900 at 894 pieces.

Frequently Asked Questions (FAQ)

Q: Can part 2800889 be used as a direct replacement for 2800878?

A: Part 2800889 is electrically and mechanically equivalent to 2800878. Both are 16A, 277V AC / 80V DC thermal magnetic circuit breakers with slide switch actuation and dual-pole configuration. The primary difference is RoHS certification status. Substitution is valid for applications where RoHS Compliant status is acceptable.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant?

A: ROHS3 refers to the third iteration of the Restriction of Hazardous Substances directive. Part 2800878 and 2800900 meet ROHS3 requirements, while part 2800889 meets the earlier RoHS Compliant standard. Both certifications restrict hazardous substances, with ROHS3 representing the current regulatory requirement.

Q: Are all three parts suitable for 277V AC and 80V DC applications?

A: Yes. All three parts—2800878, 2800889, and 2800900—are rated for 277V AC and 80V DC operation and are suitable for applications within these voltage specifications.

Q: Does packaging differ between these parts?

A: All three parts are supplied in Bulk packaging. No packaging differences exist between the main part and substitutes.

Q: Which part should be selected for new designs?

A: For new designs, part 2800878 or 2800900 are recommended due to ROHS3 Compliant status, which aligns with current regulatory standards. Both parts are electrically and mechanically identical and carry Active product status.
