Overview
The Cosel NBH-30-102 is a single-phase EMC/EMI power line filter designed for AC and DC applications. It features a rated voltage of 250 VAC and 250 VDC with a continuous current rating of 30 A. The component utilizes a two-stage filtering architecture to suppress common mode noise effectively. It employs terminal block termination for secure electrical connections. The unit is constructed as a chassis-mount module, providing robust mechanical stability for industrial environments.
Feature Summary
- Two-stage common mode noise filtering architecture
- Terminal block termination style for reliable connection
- Chassis-mount design for structural integrity
Applications
- Industrial power supply input stages
- Medical equipment power conditioning
- Telecommunications infrastructure filtering
Procurement Notes
Verify the specific datasheet revision and manufacturing date code upon order confirmation. Confirm that the terminal block specifications match the intended wiring gauge and torque requirements. Ensure the chassis mounting holes align with the installation panel dimensions. Validate compliance with relevant regional safety standards required for the final equipment assembly before deployment.
Selection Notes
Select this model when a 30 A current capacity and 250 VAC/VDC rating are required for single-phase systems. The two-stage design offers higher attenuation compared to single-stage alternatives. Consider the chassis-mount form factor if space constraints preclude PCB-mounted solutions. Verify that the terminal block interface suits the existing wiring harness configuration.
Part Context
This component belongs to the Cosel NBH series of power line filters. The series provides various current ratings and capacitance options for different EMI suppression needs. The NBH-30-102 specifically addresses high-current applications requiring robust common mode noise reduction in AC and DC power lines.
Replacement Considerations
The NBH-30-102-D is a documented variant within the same product family. Verify if the suffix indicates any functional or dimensional differences before substitution.
