1. Core Model List (With Product Descriptions)

2. Quick Interpretation of Model Naming Rules

Mastering the naming logic can help you quickly identify the core parameters and applicable scenarios of the product:

1. Series Prefix
   • UTWE: Multi-channel distribution terminal series, focusing on circuit channel expansion and distribution, the core structure is main spec/main channel + auxiliary channel.
   • UTTB: Multi-function extension terminal series, integrating photovoltaic, grounding, digital interface and other extended functions, suitable for complex industrial control scenarios.
   • UTT: Special terminal series, with customized terminal configuration for specific circuit connection needs.
2. Core Specification ParameterThe number after the series prefix (4, 2.5, 6) represents the core current-carrying specification of the terminal. The larger the value, the higher the current-bearing capacity, which determines the application scenario of the product in high, medium and low load circuits.
3. Function Suffix Mark
   • PV: Photovoltaic system dedicated, adapted to the wiring characteristics of photovoltaic power generation circuits.
   • PE/PE/L: Protection grounding function, PE/L adds phase line identification to ensure correct AC circuit wiring.
   • MT/2MT: Multi-terminal configuration, MT is multi-channel parallel, 2MT is dual-terminal special design.
   • DIO/2DIO: Digital input/output interface, with signal direction (O-U/U-O) or polarity (UL-UR) identification, suitable for industrial automation systems.
   • LA 24/LA 230: Status indicator configuration, with 24V DC and 230V AC voltage adaptation, realizing visual circuit monitoring.
   • HV: High-voltage adaptation, for high-voltage industrial circuit connection scenarios.
   • BE: Basic structure type, standard configuration for general circuit connection.
   • BU/OG: Color coding, blue/orange appearance facilitates quick circuit identification in complex wiring systems.
4. Channel Configuration Mark (UTWE Series)The format of X+1 represents X main channels + 1 auxiliary channel, which determines the circuit distribution capacity of the terminal.
