1. F-MS Series Core Model List (With Product Descriptions)

2. Quick Interpretation of F-MS Series Model Naming Rules

Mastering the naming logic of F-MS series models can help you quickly identify the core parameters and applicable scenarios of the product:

1. Series Prefix: F-MS is the core series identifier, representing Phoenix's integrated series of surge protection and circuit connection components.
2. Protection Grade Suffix:
   • T1/T2: Dual-level surge protection grade, T1 for direct lightning strike protection, T2 for indirect lightning strike and transient overvoltage protection;
   • EE: Enhanced protection level, with stronger resistance to surge impact and environmental interference.
3. Spec Parameter: The number in the model (e.g., 50, 40, 25, 2200/30, 12) represents the core electrical parameter of the component, determining the voltage, current adaptation range and protection capacity.
4. Function & Certification Mark:
   • P: With auxiliary function configuration, improving the adaptability of components in complex scenarios;
   • PVT/FM: Dual certification mark, meeting PVT performance test and FM safety certification requirements;
   • UD: Special function design, tailored for specific industrial circuit scenarios;
   • ST: Standard structure mark, indicating the component adopts universal installation and connection design.

3. Core Advantages of Phoenix F-MS Series Components

1. Diversified Protection Grades: Covers T1/T2 dual-level surge protection and EE enhanced protection, meeting the surge defense needs of different risk levels of industrial circuits, from direct lightning strike to transient overvoltage.
2. Rich Certification Support: Provides models with PVT/FM dual certification, complying with international industrial safety standards, suitable for domestic and export-oriented equipment applications.
3. Flexible Configuration Options: Includes standard type (ST), special function type (UD) and enhanced function type (P), matching the connection and protection needs of general circuits, customized circuits and critical circuits.
4. Compact & Easy Installation: All models adopt miniaturized structure design, occupying small installation space, compatible with Phoenix's standard terminal blocks and mounting rails, realizing quick plug-in and replacement.
5. Stable & Reliable Performance: Passes strict industrial environment tests, with stable operation under high temperature, high humidity and strong electromagnetic interference scenarios, ensuring long-term reliable protection of industrial circuits.

4. Product Selection Suggestions

1. Protection Grade Matching: For outdoor equipment and circuits facing direct lightning strike risks, select models with T1/T2 dual protection grades; for indoor circuits with only transient overvoltage risks, select T2 single-grade protection models; for harsh environment scenarios, prioritize EE enhanced protection models.
2. Certification Demand Selection: For critical circuits and export-oriented equipment with strict certification requirements, select models with PVT/FM dual certification; for general domestic industrial equipment, select models without special certification marks to reduce costs.
3. Function Matching According to Scenarios: For customized circuit scenarios with special function requirements, select UD special function models; for complex scenarios requiring auxiliary functions, select models with P suffix; for general circuit connection and protection, select ST standard structure models.
4. Parameter Adaptation Confirmation: According to the voltage and current range of the protected circuit, select components with matching spec parameters to avoid mismatched parameters affecting the protection effect and circuit operation.
