The Rockwell Automation/Allen-Bradley 1336F-B125-AN-EN-L6 is an adjustable frequency drive in the 1336 PLUS II family of adjustable frequency drives. The drive is rated to use an AC power supply that has a voltage of between 380 and 480 Volts AC. The 1336F-B125-AN-EN-L6 can drive a load with a rating of 125 Horsepower. The adjustable frequency drive has an IP00 rating which means that the drive can be installed in an open-type enclosure in an industrial environment. The 1336F-B125-AN-EN-L6 uses the English language for programming and displaying instructions.

The control interface for the 1336F-B125-AN-EN-L6 accommodates a voltage of 115 Volts AC. Drives in the 1336 PLUS II family, which includes the 1336F-B125-AN-EN-L6, are suitable in circuits which have the power to provide up to 200,000 RMS symmetrical amperes within a voltage of 600 Volts. Additionally, these drives have Metal Oxide Varistors (MOV) which are preinstalled. The MOVs provide phase-to-phase, surge, and phase-to-ground protection. The surge protection provided by the Metal Oxide Varistor is for transient line protection and not for continuous operation. When used in an ungrounded distribution system, the MOV protection for phase-to-ground situations is capable of turning to an uninterrupted current flowing towards the ground. The 1336F-B125-AN-EN-L6 calls for an isolation transformer or a line reactor if the AC power source has notable power disruptions. It does not have a neutral ground connection, and if the line has a power factor correction capacitor, a 5% line reactor can be used. As with other drives in the 1336 PLUS II category, a user-supplied input circuit breaker or an input fuse is recommended.
