The 1336F-BRF75-AA-EN-HAS-L4 is a user-adjustable frequency controller from Allen-Bradley. The controller is part of the Allen-Bradley 1336 PLUS II series of adjustable frequency controllers. Controllers in this series support serial communication options like the RS232, RS422, RS485, and DeviceNet communication modules. Additionally, controllers in this series feature a process mode which helps to add flexibility when monitoring the drive. The process mode allows the human-machine interface module to display 2 lines of characters with each line having 8 display character spaces and 8 programmable text character spaces. Combining the display and text characters creates a complete process display.

When installing the 1336F-BRF75-AA-EN-HAS-L4 under the NEC, UL, or CSA guidelines, fuses can be used to provide branch short circuit protection. The fuses that can be used are known for providing high interrupting capabilities. The guidelines also state that circuit breakers can be used instead of fuses. However, the circuit breakers recommended in the guidelines are magnetic trip circuit breakers. These circuit breakers work slowly on this device and their slow operation reduces their reliability to protect the 1336F-BRF75-AA-EN-HAS-L4 in the event of a short circuit. By default, the 1336F-BRF75-AA-EN-HAS-L4, like other 1336 PLUS II controllers, does not have input power short circuit protection. The Horsepower rating for the 1336F-BRF75-AA-EN-HAS-L4 is capped at 5.5 Horsepower when the drive is operating in its normal duty mode. The drive has a transistor-transistor logic (TTL) contact on its control interface. For voltage, the drive accommodates a minimum input voltage rating of 380 Volts AC and a maximum rating of 480 Volts AC. The 1336F-BRF75-AA-EN-HAS-L4 has a NEMA Type 1 enclosure.
