Phoenix Contact 2800740 Transient Voltage Suppressor - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2800740 is a Type 2 Transient Voltage Suppressor (TVS) module designed for surge protection in electrical circuits. This component is classified as obsolete, making identification of suitable substitute parts essential for system maintenance and new designs requiring equivalent functionality.

The 2800740 operates at a maximum continuous voltage of 275VAC with a nominal discharge current of 20 kA (8/20µS) and a maximum discharge current of 40 kA. Its protection level is rated at 1.35 kV, with a short circuit rating of 25 kA. The module is base-mounted and carries multiple international approvals including CSA, cUL, cULus, EAC, and UL certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2800740 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Type classification (Type 2 capability required)
• Continuous operating voltage (MCOV) equal to or greater than 275VAC
• Nominal discharge current (8/20µS) of 20 kA minimum
• Maximum discharge current (8/20µS) of 40 kA minimum
• Short circuit rating (SCRR) of 25 kA minimum
• Protection level (VP) suitable for the application circuit

Mechanical & Form Factor Requirements:

• Module-only form factor
• Single-pole configuration
• Base mount installation type

Compliance & Certification Requirements:

• RoHS compliance status
• International safety approvals (UL, cUL minimum)

The Phoenix Contact 2910336 meets these substitution criteria as an active product offering equivalent or superior electrical performance within the same product category and form factor.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2910336 is the identified substitute for the obsolete 2800740 based on the following engineering criteria:

Product Status & Availability: The 2910336 is an active product with current manufacturing status, ensuring long-term availability and supply chain continuity compared to the obsolete 2800740.

Electrical Performance: The 2910336 provides equivalent discharge current ratings (20 kA nominal, 40 kA maximum) and short circuit rating (25 kA) as the original part. The substitute features a higher continuous operating voltage (385VAC versus 275VAC) and higher protection level (1.8 kV versus 1.35 kV), making it suitable for applications requiring the original specifications and those with higher voltage margins.

Compliance & Certifications: Both parts carry UL and cUL certifications. The 2910336 meets ROHS3 compliance, exceeding the RoHS compliance of the original part. The 2800740 includes additional certifications (CSA, cULus, EAC); applications requiring these specific certifications should be evaluated against the 2910336's certification scope.

Form Factor & Installation: Both parts maintain identical form factor (Module Only), pole configuration (1), and mounting type (Base Mount), ensuring mechanical compatibility in existing installations.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2910336 directly replace the 2800740 in all applications?

A: The 2910336 meets or exceeds the electrical specifications of the 2800740 (discharge current, short circuit rating, operating temperature). However, if the original application specifically requires CSA, cULus, or EAC certifications, the substitute's certification scope should be verified against application requirements.

Q: What is the difference between Type 1 and Type 2 classification?

A: The 2800740 is classified as Type 2 only, while the 2910336 supports both Type 1 and Type 2 operation. Type classification relates to surge protection device categories defined by international standards. The 2910336's dual-type capability provides flexibility for various circuit protection applications.

Q: Why does the 2910336 have a higher protection level (1.8 kV) than the 2800740 (1.35 kV)?

A: The protection level (VP) indicates the voltage at which the device activates to suppress transients. The 2910336's higher protection level reflects its design for higher voltage applications. For circuits designed around the 2800740's 1.35 kV protection level, the 2910336 will activate at a higher threshold, which may require circuit evaluation.

Q: Are there packaging differences between these parts?

A: The 2800740 packaging is not specified in available data. The 2910336 is supplied in Bulk packaging. Packaging format should be confirmed based on procurement and assembly requirements.

Q: What is the significance of ROHS3 compliance on the 2910336?

A: ROHS3 represents the current iteration of Restriction of Hazardous Substances compliance, indicating the part meets the latest environmental and material restrictions. The 2800740 meets RoHS Compliant status. Both parts satisfy RoHS requirements; ROHS3 indicates the 2910336 meets the most current standard.
