Schneider Acti9 Series A9I48191V120H1P-100A

Model A9I48191V120H1P-100A

Model A9I48191V120H1P-100A is the complete order number of a low-voltage electrical product under the Acti9 Series of ชไนเดอร์ อิเล็คทริค. The meaning of each segment of the code and the corresponding product attributes can be explained as follows:

1. Model Segment Analysis
2. A9: Represents the major product series, namely Schneider’s Acti9 Series. This series is a standardized low-voltage component series launched by Schneider for terminal power distribution, covering miniature circuit breakers, อุปกรณ์กระแสไฟตกค้าง, disconnectors, and other products.
3. I48: Represents the product type sub-code. In combination with the naming rules of the Acti9 Series, this code usually refers to disconnectors or fuse-disconnectors, which are mainly designed for no-load switching of circuits and power isolation.
4. 191: Represents the structural characteristics and accessory configuration code. Different number combinations correspond to different installation methods (เช่น, การติดตั้งราง DIN), operation methods (เช่น, handle operation), or auxiliary contact configurations.
5. V120: Represents the rated working voltage parameter of the product. ที่นี่, `V120` indicates that the rated working voltage of the product is suitable for 120V AC circuits. It should be noted that this voltage class is common in the North American market and is incompatible with the mainstream 220V/380V voltage system in China.
6. H1P: Represents the pole number and installation specification of the product. `H1P` means a 1-pole product, suitable for the isolation requirements of single-phase circuits.
7. 100ก: Represents the rated working current of the product, เช่น., the maximum current that the component can carry stably for a long time is 100A.
8. Summary of Core Product Attributes

3. Key Precautions
4. Voltage Compatibility: The rated voltage of this product is 120V AC. It is strictly prohibited to use it directly in domestic 220V AC circuits, มิฉะนั้น, it may cause safety accidents such as component burnout and insulation breakdown.
5. Functional Positioning: Disconnectors do not have short-circuit protection or overload protection functions and are only used for circuit isolation. They must be used in conjunction with protective components such as circuit breakers.
6. Model Verification: To confirm accurate product drawings, installation dimensions, and technical manuals, you can enter the complete order number through Schneider’s official product selection tool or technical support hotline for inquiry.

Domestic Voltage-Adaptable Model Comparison Table for Schneider Acti9 Series 100A Disconnectors

The following is a complete comparison table of domestic adaptable models corresponding to the North American model A9I48191V120H1P-100A and models with different pole numbers of the same specification. These models are suitable for the mainstream 230/400V AC voltage system in China and meet the isolation requirements of single-phase/three-phase power distribution systems.

3. Key Adaptation Instructions
4. Voltage Compatibility: All domestic models are suitable for 230/400V AC (50/60เฮิรตซ์), fully compatible with the domestic power grid. It is strictly prohibited to directly use North American 120V models in domestic 220V/380V systems.
5. Functional Consistency: All domestic models retain the core functions of disconnectors—no-load circuit switching and power isolation. They do not have short-circuit or overload protection capabilities and must be used in conjunction with circuit breakers.
6. Installation Compatibility: All models adopt 35mm DIN standard rail mounting, consistent with the installation method of the original North American model, enabling direct replacement and installation.
7. คำแนะนำในการคัดเลือก:

For single-phase circuits, prioritize 1P/2P models.

For three-phase power circuits, prioritize 3P models.

For critical loads requiring simultaneous neutral wire isolation (such as medical equipment and data centers), select 4P models.

For applications requiring remote status monitoring, select models with auxiliary contacts such as A9S71690.
