Size including terminals, plate and slider knob is 3-1/16'H, 4-1/4'W and 4-1/4'D. Naturally, if there is a short circuit, the load on the transformer is much greater than it is designed to carry and it may burn out if permitted to remain in that position. Some of the older Jefferson transformers were for use with 25/40 cycle currents. Toys and other electrical apparatus that require a given battery voltage to operate require 3 to 7 volts higher voltage alternating current to do the same work. Then close the main switch and the circuit again be in service If fuses continue to blow, call your electrical dealer or lighting company. Retrieved 1, original source, Schneider Electric at schneider-electric. Connections are made from the track to posts marked R and 2 and advance the switch lever to the fifth contact. It can be rotated to make contact with multiple voltage taps in the semicircle for the different speeds. If it becomes very warm, it is an indication of too heavy a load or a short circuit and should be disconnected at once. The transformer case size is 2-1/2'H, 3-1/2'W and 3-1/2'D Size including terminals, plate and slider knob is 2-7/8'H, 4-3/8'W and 4-3/8'D. Our current product scope includes ONAN ratings up to 60 MVA with primary voltage ratings through 161kV. This transformer is intended for intermittent service and should be used only for short periods at a time. U/WThe slash indicates the two voltages are from the same winding and that both voltages are available g. IntroductionBesides making clocks, Jefferson also made many different kinds of transformers including toy (train) type, bell, radio replacement, oil burner ignition, control, luminous tube sign, door bell, signal, auto and double wound. Prefix is 'Roper/GE' And the age statement from the above website even knew that and printed in invisible type: 'This product could have been manufactured the 13th week of 1994 or 2004. It has the same voltages and wattage The model number is not marked on the transformer but is on the box. Depth including terminals is 7-3/8' Weight is 6 7 lbs Catalog No 721-111 Outdoor Non-Weatherproof type.

, Chicago, Ill For use with 110V 60 Cycle The line cord is made of two separate wires with black cloth on the outside. Bell TransformersThis early bell-ringing transformer is a single block of white glazed porcelain 1/4' thick that's open in the back. Watch out: in 1982 AEC's assets and production were sold to Federal Pioneer of Canada, maker of the FP panel brand whose hazards we discussat FP FEDERAL PIONEER in CANADAFP, originally Pioneer Electric Limited formed in Manitoba in 1946 became FPE-Pioneer Electric Limited effective in 1964, re-naming to Federal Pioneer Limited in 1972 and incorporated in Canada in 1978 In 1990 Federal Pioneer was purchased by Schneider Canada Inc.
