The CORE-A-1 ferrite core ring by Allen Bradley is designed to minimize electrical interference produced by variable frequency drives (VFDs). Each set consists of four distinct cores, with a lightweight construction of just 0.2 lbs per core. It is particularly suitable for Frame A drives that utilize electromagnetic compatibility (EMC) filters, ensuring that the operational efficiency remains unhindered.

This ferrite core possesses a voltage rating ranging from 100 to 240 volts AC, allowing it to accommodate diverse electrical setups. Additionally, it supports both 1-phase and 3-phase drive configurations. Built from nickel-zinc ferrite, the cores demonstrate excellent noise suppression qualities.

The solid toroid ring form factor of the CORE-A-1 enhances its efficiency as a noise suppression component. It operates optimally within a recommended frequency range between 10 to 300 megahertz. The device is also built to withstand a broad temperature spectrum, functioning reliably in environments ranging from -40°F to 257°F. This characteristic makes it suitable for varied industrial applications where temperature extremes might be a factor.
