Phoenix UT 6-TMC M/ECP/CTM Series Current/Voltage Matching Terminals & Contact Modules Selection Guide

Phoenix this batch of products covers three core series including UT 6-TMC M (6mm² precision current rating terminals), ECP/ECP-E3 (modular current specification terminals), and CTM (multi-contact AC/DC voltage adaptation modules). They feature 0.5A–16A wide current coverage and 12DC–110AC voltage adaptation, with modular DIN rail mounting design, suitable for industrial control circuit current matching, signal contact switching/expansion, and AC/DC voltage adaptive connection scenarios.

1. Core Model Classification & Product Specifications

Classified by product function and structural characteristics, with detailed parameter matching, product codes and application positioning for quick selection:

1.1 UT 6-TMC M Series (6mm² Precision Current Rating Terminals, 0916603-0916613)

6mm² wire gauge dedicated precision current rating terminals, with single fixed current grade (0.5A–16A), clear current marking, modular design, suitable for fixed current matching of 6mm² control/power circuits (one terminal for one current grade, high matching accuracy).

1.2 ECP/ECP-E3 Series (Modular Current Specification Terminals, 0912018-0912052/0916536)

Divided into ECP-E3 enhanced type (1A–12A single current grade) and ECP basic type (current segment matching: 1-2A/3-6A/10A), small-size modular design, suitable for small wire gauge control circuit current segment matching (cost-effective, wide current coverage for one module).

1.2.2 ECP Basic Type (Current Segment Matching, 0912018/0916536/0912020)

1.3 CTM Series (Multi-contact AC/DC Voltage Adaptation Modules, 2838500-2838610)

Small-size contact modules with two contact configurations (2X1/1X2), supporting 12DC–110AC wide voltage adaptation (DC 12/24/60V, AC 110V), suitable for signal circuit contact switching/expansion, AC/DC voltage adaptive signal transmission (one module for multi-path contact, compact structure).

2. Quick Interpretation of Model Naming Rules

The naming logic of the three series follows Phoenix's standardized industrial terminal/module specification, with each segment corresponding to clear wire gauge, current/voltage, structure/configuration parameters:

3. Core Advantages of This Batch of Products

3.1 UT 6-TMC M Series

1. 6mm² fixed wire gauge + precision current rating: 0.5A–16A full current coverage, one terminal for one current grade, high matching accuracy for 6mm² circuit.
2. Modular DIN rail mounting: Adapt to standard NS35/32 rail, consistent with Phoenix other terminal series, standardized cabinet wiring.
3. Clear current marking: Integral current grade marking, no additional labeling, reducing maintenance errors in complex circuits.

3.2 ECP/ECP-E3 Series

1. Two-tier product positioning: ECP-E3 enhanced type with high-stability contact for precision current matching; ECP basic type with current segment coverage for cost-sensitive scenarios.
2. Small-size modular design: Compact structure, saves cabinet installation space, suitable for small wire gauge control circuit dense wiring.
3. Wide current coverage: 1A–12A full coverage for ECP-E3; 1-2A/3-6A/10A segment coverage for ECP, meeting most small current control circuit needs.

3.3 CTM Series

1. Dual contact configuration + wide voltage adaptation: 2X1 (expansion) /1X2 (shunt) two configurations, 12DC–110AC AC/DC voltage coverage, one module for multiple signal circuit needs.
2. Miniaturized design: Ultra-small form factor, suitable for narrow-space equipment internal signal circuit wiring.
3. Diverse application modes: Support contact switching, signal expansion, one-to-two shunt, adapt to different signal transmission topologies.

4. Product Selection Suggestions

4.1 Select by Current Matching Requirement & Wire Gauge

1. 6mm² wire gauge circuit (0.5A–16A): Prioritize UT 6-TMC M series (precision single current grade, high matching accuracy, e.g., 0916605 UT 6-TMC M 2A for 2A 6mm² signal circuit).
2. Small wire gauge control circuit (1A–12A): Choose ECP/ECP-E3 series (ECP-E3 enhanced type for high stability needs, e.g., 0912042 ECP-E3 2A; ECP basic type for cost-sensitive, e.g., 0912018 ECP 1-2 for 1-2A segment).
3. No wire gauge limit, focus on contact switching/voltage adaptation: Select CTM series (match by contact configuration and voltage, e.g., 2838513 CTM 1X2-24DC for 24V DC one-to-two signal shunt).

4.2 Select by Functional Requirement (Current/Signal)

1. Pure current matching/fixed (no contact switching): Choose UT 6-TMC M or ECP/ECP-E3 (current-oriented terminals, high current stability).
2. Signal contact switching/expansion/shunt (with voltage adaptation): Must select CTM series (contact-oriented module, support AC/DC voltage and multi-path contact).

4.3 Select by CTM Contact Configuration & Voltage

1. Signal circuit expansion (one signal to two independent circuits): Choose 2X1 configuration (2 groups 1 channel, independent expansion, e.g., 2838500 CTM 2X1-24DC).
2. Signal circuit one-to-two shunt (one signal to two parallel circuits): Choose 1X2 configuration (1 group 2 channels, parallel shunt, e.g., 2838513 CTM 1X2-24DC).
3. DC signal (12/24/60V): Select DC voltage models (e.g., 12DC for small equipment, 24DC for industrial mainstream, 60DC for medium DC voltage).
4. AC signal (110V): Select 110AC models (e.g., 2838526 CTM 2X1-110AC, 2838539 CTM 1X2-110AC).

4.4 Select by Cost & Stability Requirement

1. High stability/precision matching (industrial control core circuit): Choose UT 6-TMC M (6mm²) or ECP-E3 (small current) (enhanced structure, low failure rate).
2. Cost-sensitive/general circuit (non-core signal/control): Choose ECP basic type (current segment) (one module covers multiple current grades, low cost).
