Supplementary Key Remarks
- 200V single/3-phase P7 models (P7E / P72 series) are excluded from the above table. This list only covers mainstream industrial 400V 3-phase fan & pump models P7U.
- Model Abbreviation Rule: The trailing digit 0 is often omitted in engineering drawings and procurement documents. Например, CIMR-P7U41600 is abbreviated as CIMR-P7U4160.
- Cabinet Classification: Models ≤132kW adopt standard wall-mounted cabinets; models ≥160kW (4160 и выше) are large floor-standing cabinets equipped with independent high-power cooling fans.
- Distinction of output versions at the same power rating:
Standard built-in braking transistor; high-power models 4160 and above require an external braking unit + braking resistor to implement dynamic braking during deceleration.
