Schneider Masterpact MT16H1b MIC2.0 1600A-3P is a product of the MT series, designed for the protection and control of distribution lines and equipment in the low-voltage distribution field.
Model Explanation
MT: Designates Schneider’s MT series air circuit breakers.
16: Represents a frame current of 1600A.
H1b: Indicates the breaking capacity class, suitable for industrial applications with high breaking capacity requirements, with a breaking capacity of 85kA.
MIC2.0: Denotes the trip unit type, an intelligent trip unit with basic overload and short-circuit protection functions.
1600A: The rated current of the circuit breaker.
3P: Means three poles.
Main Specifications
Rated Voltage: The rated insulation voltage is 1000V, the rated operational voltage is 690V, suitable for AC 50/60Hz circuits.
Breaking Capacity: 85kA.
Mechanical and Electrical Life: The mechanical life is generally up to 12,500 operations, and the electrical life varies under different voltage conditions, e.g., 6,000 operations at 440V.
Mounting Types
Two mounting types are generally available: fixed type and drawout type, which can be configured according to actual application scenarios and maintenance requirements.
Application Fields
Suitable for five major markets including industry, energy and infrastructure, commercial and public buildings, residential buildings, and data centers. It can provide fault protection such as overload, short circuit, overcurrent, voltage loss and undervoltage for lines.
The dimensional data of Schneider Masterpact MT16H1b MIC2.0 1600A-3P is as follows (official standard, unit: mm, format: Height × Width × Depth):
- Mounting Type & Dimensional Comparison
| Mounting Type | Dimensions (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
Width (W): Horizontal length (for 3P pole configuration)
Depth (D): 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 (ABB), M class (Siemens), 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 standard, 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 (e.g., ABB PR121/P-LSI, Siemens ETU600-LSI, Chint MF3).
