Hidria 450mm, 400V 3Ph Axial Fan
Made in Slovenia, Europe
The Hidria model R13R-4530A-4T2-35100 (manufacturer part code 0313-4-0465) is a three-phase, high-efficiency AC axial fan. This model features a 3-phase external rotor motor that supports dual-speed operation depending on whether you wire it in a Delta (Δ) or Star (Y) configuration. It has a sucking airflow direction and an outer blade diameter of 450 mm.
- Fan Diameter: 450 mm
- Model Number :R13R-4530A-4T2-35100

🛠️ Mechanical & Physical Properties
- Fan Diameter: 450 mm rotor blade sizing.
- Overall Basket Outer Diameter: 515 mm attachment framework.
- Airflow Pattern: Sucking (draws air through the basket/grill, across the blades and motor).
- Static Efficiency Grade: N = 41.0 (Compliant with ErP eco-design directives).
- Overall Static Efficiency: 32.0%.
🛡️ Insulation & Environmental Protection
- Insulation Class: Class 155 (F) standard thermal rating.
- Enclosure Protection: IP54 sealing against water splashes and dust.
- Airflow Pattern: Sucking (draws air through the basket/grill, across the blades and motor).
- Thermal Protection: Integrated thermal contacts (TK / Thermocontact) built into the windings. These must be wired to an external control unit to shut off power during overload faults.
- Temperature Limits: Operates down to a minimum of -30 °C and can withstand up to a maximum ambient temperature of 70 °C.
🔌 Basic Wiring Framework
The fan utilizes standard 3-phase speed switching logic:
- High Speed (Delta - Δ): Bridge links join terminal connections [U₁ and W₂, V₁ and U₂], and [W₁ and V₂] to the respective L₁, L₂, L₃ supply lines.
- Low Speed (Star - Y): Tie terminals U₂, V₂, and W₂ together to create the star point, then feed L₁, L₂, L₃ directly into U₁, V₁, W₁.
- Rotation Direction: Change direction simply by interchanging any two phases.
