The 1336-GF-SP3A is a ground fault current transformer that has been designed and manufactured as a spare part for the 1336 series drives. This spare part belongs to the Allen-Bradley 1336 Product Line. Grounding transformers like this one are applied primarily to guarantee the proper functioning of electrical distribution systems. The Allen-Bradley 1336-GF-SP3A ground fault current transformer belongs to the E frame series which has a Horsepower rating of 150 to 300 Horsepower. This transformer is compatible with drives that belong to the same frame and Horsepower ratings. The Allen-Bradley 1336-GF-SP3A ground fault current transformer is essential for assembling a grounding system. The main function of this spare part is to control the voltage range of the drive respecting the ground voltage and it provides a path that enables the user to detect erratic connections between line and phase conductors.

Grounding mechanisms like these provide a neutral point to high-voltage systems and it allows the users to detect unwanted connections. Once a connection has been detected, it sends a signal to trip the protection devices so they can remove the excess voltage on the affected conductors. Being compatible with 1336 drives, the 1336-GF-SP3A’s installation can be performed in cabinets and it can be connected to the grounding system by the means of a common grounding point. The installation of this ground fault current transformers provides connections directly through the drive cabinet. The importance of the Allen-Bradley 1336-GF-SP3A ground fault current transformer lies in the fact that while monitoring the whole system, it can not only detect faults but identify when a fault has occurred and address the location and type of the fault. This transformer will improve the grounding process of any drive and it will help preserve the life of all the equipment connected to the drive or involved in the process.
