NBM-16-331

Overview

The Cosel NBM-16-331 is a single-phase power line filter designed for AC 250V and DC 250V applications. It supports a rated current of 16A with a capacitance of 330pF, resulting in a maximum leakage current of 75uA (typical 37.5uA). The unit features chassis mount installation via push-down terminals and belongs to the NB series.

Feature Summary

• Low leakage current design suitable for sensitive medical or electronic equipment
• Two-stage filtering architecture for effective EMI/EMI suppression
• Push-down terminal connection method for secure wiring

Applications

• Medical device power input protection
• Industrial control systems requiring low leakage
• Electronic equipment chassis mounting

Procurement Notes

Verify the specific suffix requirement; the base model NBM-16-331 differs from the DIN-rail variant NBM-16-331-D. Confirm terminal type compatibility with existing panel designs. Check RoHS compliance status directly with the manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when chassis mounting is required rather than DIN-rail options. Ensure the 16A current rating meets system load requirements. Verify that the 330pF capacitance value aligns with leakage current limits imposed by safety standards for the intended application environment.

Part Context

This part belongs to the Cosel NB series of power line filters. It is distinct from the NBM-16-331-D, which utilizes a different mounting style. The series focuses on providing EMC/EMI suppression for single-phase power lines while maintaining strict leakage current controls.

Replacement Considerations

The NBM-16-331-D is a related variant but uses DIN rail mounting instead of chassis mounting. Direct replacement requires verifying mechanical fit and terminal interface compatibility between the two models.
