Ideal Applications
This three phase EMI filter is designed for industrial systems where a 10A current rating matches the load profile and conducted EMI must be controlled:
- Variable Frequency Drives (VFDs) and Motor Control Systems – They are used in variable frequency drives and industrial automation, where switching transitions generate significant common-mode and differential-mode noise that feeds back into the power line
- Industrial Automation Equipment and Packaging Machinery – Protect PLCs, sensors, and communication buses from power line noise generated by nearby switching loads
- CNC Machine Tools and Precision Manufacturing Equipment – Prevent interference from affecting positioning accuracy, tool control signals, and data integrity
- HVAC Systems and Industrial Air Conditioning Units – Ensure reliable compressor motor operation and protect building management system electronics
- Textile Machinery and Processing Equipment – Suppress EMI from multiple motor drives operating simultaneously on shared power lines
If your three phase system draws up to 10A and requires electromagnetic compatibility compliance, this emi filter fits your needs. For higher current requirements, review our full three phase EMI filter range.
Insertion Loss Performance
The DOREXS three phase EMI filter 10A is engineered to provide stable insertion loss performance against both:
- Common Mode Noise Reduction-Helps suppress interference transmitted between line conductors and ground.
- Differential Mode Noise Reduction-Reduces noise generated directly across power conductors.
Mechanical Design

FAQ
How Our 10A Three Phase EMI Filter Works
- Simple Installation Mount the filter between the power source and your equipment using standard electrical connections. Filters must be installed close to the source of electrical noise for optimal performance-position the unit as near to the noise-generating equipment as possible and ensure a solid, low-impedance ground connection.
- Active Filtering Internal series inductors present high impedance to high-frequency noise on all three phases, while shunt capacitors divert unwanted currents away from your equipment. Common-mode noise appears as the same unwanted signal on all three phases relative to earth, and the common-mode choke addresses this directly. Differential-mode noise exists between the phases of the filter and is suppressed by line-to-line capacitors and individual phase inductors. The filter operates passively-no external power required.
- Clean Power Delivery Your equipment receives filtered AC power with significantly reduced electromagnetic interference. The mains frequency (50/60 Hz) passes through with minimal voltage drop or power loss, while conducted noise across the 150 kHz to 30 MHz range is attenuated. The result is improved EMC performance in your industrial automation applications and protection for downstream electronics.
Why choose a 10A Three Phase EMI Filter?
A 10A model is ideal for low- to medium-power industrial equipment such as servo drives, VFDs, automation systems, and machine tools requiring reliable EMI suppression.
Is it compatible with both 3-wire and 4-wire three phase systems?
Yes. DOREXS offers configurations for both delta (3-wire) and wye (4-wire) connections to match your system requirements. The choice affects capacitor arrangement and leakage current characteristics-our team can help you choose the right configuration.
How long does delivery typically take?
Standard models in stock ship within 8–12 days to your shipping address. Custom configurations-including specific capacitor values, modified attenuation profiles, or non-standard mounting-are typically available in 3–4 weeks. Shipping fee and total price depend on quantity, country of arrival, and shipment method. Contact us to confirm delivery timelines and purchase options for your order.
What if the filter doesn't meet my EMC requirements?
Our engineering team provides pre-installation EMC consulting and post-installation support to ensure compliance. If a standard unit proves unable to achieve required attenuation, we can engineer a custom solution or add supplementary filtering stages. We stand behind our products with a warranty and customer satisfaction commitment.
Can you customize the filter for specific applications?
Absolutely. DOREXS specializes in custom EMI filter solutions based on your exact current, voltage, and EMC requirements. Submit your specifications or EMC test data, and our engineers will design a filter that addresses your specific noise profile. Proper installation of EMI filters is essential for effective noise suppression, and we provide detailed guidance for every custom unit.
Do you accept returns?
Standard product returns are eligible within the specified return period. Custom-engineered items may be subject to different withdrawal terms. Contact us for full details on our refund policy-we work to ensure every customer is satisfied with their purchase.
