Type TF and EOF transformers consist 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 transformers have the same footprint as the Type T. This design frees up space normally used for separate fuse blocks. Type TF transformers consist 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. This Industrial Control Transformer is 1 phase, and has a rated power of 150 VA. This transformer has a primary voltages such as 240 x 480 V and a secondary voltage of 24 V with a temperature rise of 55 °C. This product complys to UL , CSA & NOM standards.
