Phoenix FAME/MT/GTF Series Terminal Blocks & Functional Modules Selection Guide

Phoenix this batch of products covers 3 core series including FAME (multi-core integrated connection modules), MT (marking/1.5mm² dedicated terminals, MTTB/MTK/MTKD/MT sub-series), and GTF (voltage-matched protection modules). The main compatible wire cross-section is 1.5mm², integrating multi-core signal/power+ground transmission, circuit marking, special material adaptation, explosion-proof, and voltage-specific protection functions. They are widely used in industrial control cabinet wiring, circuit identification, harsh environment signal transmission, and voltage-specific overcurrent protection scenarios.

1. Core Model Classification & Product Descriptions

The series is categorized by product function and sub-series for quick matching of application needs, with key parameters including core count, structural type, material attribute, and rated voltage:

1.1 FAME Series Multi-core Integrated Connection Modules

Featured with X+1 core structure (X=4/6/8 signal/power cores + 1 ground core), realizing integrated transmission of multi-channel signal/power and grounding protection; divided into WP/TP/BP functional types and basic models, suitable for mixed signal/power circuit wiring.

1.2 MT Series (1.5mm² Dedicated + Marking Terminals)

Covers 4 sub-series, focusing on 1.5mm² wire spec (mainstream micro-signal/ low-power circuit) and circuit marking functions; MTKD sub-series has diverse special materials and explosion-proof attributes for harsh environments.

1.3 GTF Series Voltage-specific Protection Modules

Dedicated protection modules with fixed specification 76 and rated voltage matching, suitable for overcurrent/ overvoltage protection of industrial circuits with specific voltage requirements.

2. Quick Interpretation of Model Naming Rules

The naming logic follows Phoenix's standardized industrial terminal specification, with each segment corresponding to clear product parameters and functional attributes:

3. Core Advantages of This Batch of Products

1. Integrated Function & Space SavingFAME series X+1 core structure integrates multi-channel signal/power transmission and grounding protection, eliminating additional grounding terminals; MT TWIN dual-wire structure saves 50% cabinet space for 1.5mm² high-density wiring.
2. 1.5mm² Spec Focus & Strong CompatibilityMT series is fully optimized for 1.5mm² (mainstream micro-signal/ low-power wire spec), covering connection, marking, grounding, and explosion-proof functions, matching most industrial low-power circuit needs.
3. Diverse Environmental AdaptabilityFAME has waterproof/high-temperature/enhanced protection types; MTKD has special alloy materials and explosion-proof (-EX) models; the whole series adapts to outdoor, high-temperature, explosive, and high-interference industrial sites.
4. Clear Circuit Identification & High SafetyMT series blue color-coded (-BU) models realize visual signal circuit distinction; grounding (-PE) and enhanced insulation (-LOE) models improve circuit safety; GTF series voltage-specific protection avoids overvoltage/overcurrent damage.

4. Product Selection Suggestions

1. Select by Core Function & Application Scenario
   • For multi-channel signal/power + grounding mixed wiring: Choose FAME series (WP for waterproof, TP for high-temperature, BP for enhanced protection, e.g., FAME-WP 4+1, FAME 6/4+1).
   • For 1.5mm² circuit basic connection: Select MTTB/MT basic models (e.g., MTTB 1,5, MT 1,5).
   • For 1.5mm² circuit marking/ identification: Use MTK/MTKD series (standard marking with MTK, harsh/explosive environment with MTKD-EX, e.g., MTK-P/P BU, MTKD-NICR/NI EX).
   • For circuit overvoltage/overcurrent protection: Adopt GTF series (230V AC with GTF 76/230, 48V DC with GTF 76/48).
2. Select by 1.5mm² Circuit Layout & Safety Requirements
   • For high-density 1.5mm² wiring: Choose MT 1,5-TWIN/MT 1,5-TWIN-PE dual-wire models (grounding needed with -PE suffix).
   • For 1.5mm² signal circuit identification: Select MT 1,5 BU/MTK-P/P BU blue color-coded models.
   • For 1.5mm² circuit grounding protection: Use MT 1,5-PE/MT 1,5-TWIN-PE models.
   • For high-safety 1.5mm² signal circuit: Select MTK-LOE/LOE enhanced insulation models.
3. Select by Harsh Environment Adaptation Needs
   • For outdoor/humid environments: Choose FAME-WP waterproof models + MT standard models.
   • For high-temperature industrial sites: Select FAME-TP high-temperature models + MTKD-NICR/NI alloy material models.
   • For explosive hazardous environments: Use MTKD-EX explosion-proof models (e.g., MTKD-FE/CUNI EX).
   • For vibration/high-interference sites: Adopt FAME-BP enhanced protection models.
