Schneider Electric offers Type TF transformers with factory-installed overcurrent protection fuse blocks. The Type TF transformer consists of two primary fuse blocks and one secondary fuse block, a configuration that meets the majority of overcurrent needs by panel builders and machinery OEMs.
Since the fuse blocks are pre-wired and mounted on top of the transformer, the Type TF transformer has the same footprint as the Type T transformer. This design frees up space normally used for separate fuse blocks.
