content: Murdock No. 453 fuse block. Marked: "Wm. J. Murdock Co. / Chelsea Mass. / Chicago San Francisco". This unit is designed for use in a radio transmitting station to protect against transformer "kickback" power surges and inductive effects. Three carbon rods (one missing) oppose the flow of low frequency primary current, yet offer a low impedance path to ground for high frequency kickbacks. Slate base, two 15 amp - 250 volt fuses, and three resistance rods. Reference: Murdock Apparatus Catalog No. 14, 1914, page 31.
