Toshiba nC1 Low Voltage Standard Duty Micro Drive

Toshiba Updated: 2007-07-17

The nC1 Adjustable Speed Drive is a sub-micro, or nano-sized, drive with a full range of features to meet the needs of nearly any user. The nC1 is designed to be a simple drop in replacement for a starter on an existing project or as a new installation. It comes with either single-phase or three-phase input with input voltage as low as 120 V. This makes it an excellent choice for small OEM applications. Side-by-side mounting and the vertical construction of the unit allow for a smaller footprint in your cabinet. The nC1 provides better control of your application, more protection for your motor and more room in your cabinet.
