ABB NINP-61C Input Protection Card

Overview

The NINP-61C (Order No. 61353372) is an input protection card developed by ABB for use in ACS600 series inverter systems.
It functions as a protective interface between external power or control inputs and the internal electronics of the drive, mitigating the effects of electrical surges, fast transients, and voltage disturbances commonly encountered in industrial environments.

By limiting overvoltage stress and filtering high-energy interference, the card helps preserve sensitive drive circuitry, reduce unplanned outages, and extend overall system service life.

Functional Role

Installed within ACS600 inverters, the NINP-61C (61353372) absorbs and suppresses abnormal electrical events before they reach critical control and power sections.
Its design supports stable drive operation in installations subject to fluctuating supply conditions, inductive load switching, or electrically noisy plant networks.

The module is supplied either as an individual spare part or as part of ABB maintenance and service kits.
