ABSTRACT:
An electric immersion heater comprises a plurality of U-shaped heater sheaths having the terminal leads of the coils in the legs thereof extending up into a junction box from which the sheaths depend. The immersion heater is provided with a centrally disposed metal tube having the top thereof extending into the junction box and the bottom thereof contacting a metal support plate used to hold the legs of the U-shaped heater sheaths in spaced relation. The support plate is located at the level of the upper ends of the coils in the sheaths. A replaceable cylindrical cartridge is provided which encapsulates a one-shot thermal cutoff. The portion of the end lead terminals of the thermal cutoff extending above the upper end of the cartridge are twisted together and sufficiently stiff and long enough to enable the cartridge to be inserted into the tube so as to be seated therein. Quick connectors located in the junction box are used to join the lead terminals of the coils and the thermal cutoff in a circuit with the terminals of the power lines.
