Description

5-500HP

P7/Bypass

NEMA 3R

P7BR

The P7/Bypass package in a NEMA 3R enclosure is a 3-contactor style bypass, allowing motor operation from

either the drive or across the line. This facilitates drive maintenance while the motor continues to operate. The

P7 and P7/Bypass have been designed for flexibility in providing the features and options commonly demanded

by facility designers.

The P7 Drive is a variable torque AC drive, designed specifically for industrial applications. A new benchmark

for size, cost, performance, benefits and quality, the P7 includes numerous built-in features such as Network

Communications, H/O/A, PI control and energy savings functions.

The P7 has embedded communications for Modbus. An optional interface card is also available for DeviceNet,

Profibus, EtherNet and LonWorks.

This P7 package has a UL Type 3R rating.
