1336F-B020-AN-ES

The Allen-Bradley 1336F-B020-AN-ES drive is a basic adjustable frequency drive from the 1336 PLUS II series. Its input is designed for direct connection to 3-phase AC power supplies that can provide it with 380 to 480 Volts AC input voltage. The frame size of the 1336F-B020-AN-ES drive is Size B. It is also compatible with single-phase AC power supplies, but the full output power rating is only possible with 3-phase input voltage. The 1336F-B020-AN-ES drive has variable torque and constant torque capabilities. The rated constant torque output of the drive is 20 Horsepower, and the rated variable torque output is 25 Horsepower. Installing an input fuse or circuit breaker is recommended for short-circuit protection. The compatible fuse and circuit breaker ratings are listed in the 1336F-B020-AN-ES drive manual.

The Allen-Bradley 1336F-B020-AN-ES 1336 PLUS II series adjustable frequency drive’s components can be damaged by electrostatic discharge (ESD). ESD precautions during installation and maintenance are mandatory for preventing drive damage. The DC bus on the drive carries high voltages. The nominal DC bus voltage rating is 648 Volts DC. The drive trips if the DC bus voltage either exceeds 810 Volts DC or falls below 400 Volts DC. The DC bus must be discharged completely prior to any drive maintenance activity. Failure to discharge the DC bus can lead to electric shock. Personnel working on the drive can measure the DC bus voltage on TB1 (terminal block 1) to ensure that the DC bus capacitor voltage is 0.0 Volts DC before they begin their work. The language option available on the 1336F-B020-AN-ES drive is Spanish. The enclosure of the 1336F-B020-AN-ES is open and it has an IP 00 ingress protection rating.
