The dimensional data of Schneider Masterpact MT16H1b MIC2.0 1600A-3P is as follows (official standard, unit: มม, format: Height × Width × Depth):
- Mounting Type & Dimensional Comparison
| Mounting Type | ขนาด (H×W×D) |
| Fixed Type | 352×422×297 mm |
| Drawout Type | 439×441×395 mm |
- Key Notes
- Model Classification Basis: MT16H1b belongs to the MT08-40N2/H1/H1b/H2/H3/L1 dimensional series, which is different from the MT06-16N1 series. Attention should be paid to the distinction when purchasing switchgear or designing installation space.
- Dimensional Definition:
Height (H): Vertical length
ความกว้าง (ว): Horizontal length (for 3P pole configuration)
Depth (ดี): Front-to-rear length (including the main unit and standard accessories)
- Impact of Trip Unit: The MIC2.0 trip unit is a standard configuration, which does not change the basic overall dimensions and only affects the wiring of the control circuit and protection functions.
- Accessory Expansion: If special accessories (such as communication modules, extended protection units) are installed, the depth may increase slightly, and a margin of about 10–20 mm is recommended.
The following are the equivalent models of mainstream brands for Schneider Masterpact MT16H1b MIC2.0 1600A-3P, accurately matched according to key parameters (1600A/3P/85kA/LI protection), with mounting types and trip unit types marked for convenient direct replacement and selection.

Key Considerations for Replacement and Selection
- Protection Function Matching: Ensure the trip unit of the replacement model is equipped with LI two-stage protection (overload long-time delay + short-circuit instantaneous), consistent with the MIC2.0 function, to avoid insufficient protection or maloperation.
- Breaking Capacity Class: The breaking capacity of the target model should be ≥ 85kA, corresponding to S/H class (เอบีบี), M class (ซีเมนส์), and H class (domestic brands).
- Installation Dimension Adaptation: The dimensions of air circuit breakers of the same specification from different brands may vary. Check the installation holes and internal switchgear space before replacement (Schneider fixed type: 352×422×297mm; drawout type: 439×441×395mm).
- Auxiliary Function Compatibility: If accessories such as undervoltage release, shunt release and auxiliary contacts are required, select them in matching with the replacement model to ensure the interface is compatible with the control circuit.
- Electrical Connection Mode: Confirm that the incoming and outgoing line mode (front connection/ rear connection/ vertical/ horizontal) is consistent with the original design to avoid wiring modification.
Supplementary Notes
All the above models comply with IEC 60947-2 มาตรฐาน, suitable for AC 50/60Hz distribution systems with 690V and below, and can directly replace Schneider MT16H1b for line protection and control.
If it is necessary to upgrade protection functions (such as LSI three-stage protection, earth fault protection), trip unit models with LSI function from corresponding brands can be selected (เช่น, ABB PR121/P-LSI, Siemens ETU600-LSI, Chint MF3).
