Phoenix Contact 2800858 Circuit Breaker Thermal Magnetic 1A 277VAC 50VDC

Part Overview

The Phoenix Contact 2800858 is a thermal magnetic circuit breaker rated for 1A at 277V AC and 50V DC, featuring a slide switch actuator and single-pole configuration in a holder mounting type. This component is classified as Active product status and is RoHS Compliant. Circuit breakers of this specification are essential in electrical distribution systems where overcurrent protection and thermal management are required. Alternative models become necessary when addressing inventory constraints, compliance variations, or specific application requirements across different production batches or procurement cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2800858 is determined by strict equivalence across the following critical parameters: thermal magnetic breaker type, 1A current rating, 277V AC voltage rating, 50V DC voltage rating, single-pole configuration, slide switch actuator, and holder mounting type. All three parts (2800858, 2800836, and 2800847) share identical electrical and mechanical specifications within the CB series. These parts are functionally interchangeable at the component level. Variations in RoHS compliance status (RoHS Compliant versus ROHS3 Compliant) and REACH status do not affect electrical or mechanical substitutability but reflect different manufacturing or certification batches.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and are manufactured by Phoenix Contact within the CB series. The 2800858 carries RoHS Compliant certification, while 2800836 and 2800847 carry ROHS3 Compliant certification. Selection between these parts should be based on compliance requirements specific to the end application or regional regulatory framework. Parts 2800836 and 2800847 additionally carry REACH Unaffected status. From an electrical and mechanical standpoint, all three parts are equivalent and suitable for direct substitution in applications requiring a 1A thermal magnetic circuit breaker rated for 277V AC and 50V DC operation with slide switch actuation.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 2800836 or 2800847 be used as direct replacements for 2800858?

A: Yes. All three parts share identical electrical specifications (1A, 277V AC, 50V DC), mechanical configuration (thermal magnetic, single-pole, slide switch, holder mount), and series designation (CB). They are functionally equivalent at the component level.

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

A: Both certifications indicate compliance with Restriction of Hazardous Substances directives. ROHS3 represents a more recent iteration of the standard. The difference does not affect electrical or mechanical performance and should be selected based on application compliance requirements.

Q: Are there any inventory considerations when selecting between these parts?

A: Current inventory levels are 741 pcs for 2800858, 766 pcs for 2800836, and 930 pcs for 2800847. Selection may be influenced by procurement lead times and availability requirements.

Q: Does REACH status affect substitutability?

A: REACH status (Unaffected for 2800836 and 2800847) indicates regulatory classification but does not alter electrical or mechanical substitutability. Selection should align with supply chain compliance documentation requirements.

Q: Are all three parts suitable for the same voltage and current applications?

A: Yes. All three parts are rated identically at 1A current and 277V AC / 50V DC voltage. They are suitable for identical applications without derating or performance modification.
