I10SNA-T32BUL

I10SNA-T32BUL is a 3-phase AC input choke (line reactor) for industrial frequency inverters and power drive systems. It suppresses line-side harmonics, limits inrush current, smooths grid voltage fluctuations, and protects inverters from surge and transient interference. It also improves power factor and extends the service life of drive units.

Description

1. General Description

I10SNA-T32BUL is a 3-phase AC input choke (line reactor) for industrial frequency inverters and power drive systems. It suppresses line-side harmonics, limits inrush current, smooths grid voltage fluctuations, and protects inverters from surge and transient interference. It also improves power factor and extends the service life of drive units.

2. Model Definition

  • I10: Series code for standard 3-phase line reactor

  • SNA: Standard industrial type, air-cooled design

  • T32: Rated current: 32 A

  • BUL: Terminal type & insulation class for low-voltage industrial application

3. Technical Specifications

  • Rated Voltage: 3 × AC 400 V, 50/60 Hz

  • Rated Current: 32 A (continuous)

  • Inductance: Standard inductance for harmonic suppression and current smoothing

  • Insulation Class: Class F

  • Cooling Method: Natural air cooling

  • Protection Class: IP00 (for cabinet internal installation)

  • Ambient Temperature: -10 °C ~ +45 °C

  • Mounting: Floor / base plate mounting inside control cabinet

  • Application Scope: Matches inverters with power up to 15 kW @ 400 V

4. Key Features

  1. Harmonic Suppression: Reduces grid current harmonics generated by PWM rectifiers.

  2. Inrush Current Limiting: Restricts peak current during inverter power-on.

  3. Voltage Stabilization: Resists grid voltage spikes, dips and transient interference.

  4. Device Protection: Effectively protects inverter rectifier bridge and power modules.

  5. Power Factor Improvement: Optimizes overall power quality of the drive system.

  6. Durable Structure: Robust coil and iron core, low noise, stable performance for long-term operation.

5. Compatibility & Application

  • Suitable for most mainstream 3-phase low-voltage inverters, including SEW MOVITRAC 31C, MC07B series.

  • Ideal for sites with poor power grid quality, long power cables, or multiple drives running in parallel.

  • Recommended to install at the AC input side of the inverter.

6. Installation & Notes

  • Install inside ventilated control cabinet; keep sufficient clearance for heat dissipation.

  • Strictly follow wiring sequence: Grid → Line reactor → Inverter input terminal.

  • Do not exceed rated continuous current to avoid overheating.

  • Keep away from sensitive signal cables to prevent electromagnetic coupling interference.

7. Product Status

Standard industrial component, mass-produced and widely available.
