Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 2800844 are identified based on parametric equivalence within the CB series. The substitution criteria are strictly limited to the following electrical and mechanical parameters:

• Current Rating: 12A
• Voltage Rating - AC: 277V
• Voltage Rating - DC: 50V
• Breaker Type: Thermal Magnetic
• Actuator Type: Slide Switch
• Number of Poles: 1
• Mounting Type: Holder
• Series: CB
• Manufacturer: Phoenix Contact

Parts meeting all of these criteria are classified as parametric equivalents and are directly interchangeable with the 2800844 in applications requiring identical electrical protection characteristics and mechanical interface specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2800844, 2800855, and 2800866—are Active status products from Phoenix Contact's CB series with identical electrical and mechanical specifications. Each part maintains ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for industrial applications. Selection between these parts may be based on inventory availability and lead time considerations, as all three are functionally equivalent for applications requiring 12A thermal magnetic protection at 277V AC and 50V DC with slide switch actuation in single-pole holder configuration.

Frequently Asked Questions (FAQ)

Q: Are Phoenix Contact 2800844, 2800855, and 2800866 directly interchangeable?

A: Yes. All three parts are parametric equivalents within the CB series, sharing identical current ratings (12A), voltage ratings (277V AC, 50V DC), breaker type (thermal magnetic), actuator type (slide switch), pole configuration (1-pole), and mounting type (holder). Direct substitution is supported without circuit modification.

Q: What determines substitution eligibility for the 2800844?

A: Substitution eligibility is determined by matching all electrical parameters (12A current rating, 277V AC, 50V DC), breaker technology (thermal magnetic), control interface (slide switch), pole count (1), and mechanical mounting (holder) within the Phoenix Contact CB series.

Q: Do all substitute parts have the same compliance certifications?

A: Yes. Parts 2800844, 2800855, and 2800866 all carry ROHS3 compliance and REACH Unaffected status, ensuring equivalent regulatory compliance across all three options.

Q: Can these parts be used in both AC and DC applications?

A: These parts are rated for operation at 277V AC and 50V DC. Application selection must respect both voltage and current specifications for the intended circuit protection requirement.

Q: Are there packaging differences between these substitute parts?

A: All three parts are supplied in Bulk packaging. No packaging format differences exist between the 2800844, 2800855, and 2800866.
