ABSTRACT:
There is provided an improved core for an electrically heatable catalytic converter, and an electrically heatable catalytic converter containing such core, said core characterized by having a plurality of subcircuits in which the heater strips of thin high temperature resistive metal alloy are in parallel and connected between an outer shell segment and a central structural member, and the plurality of such subcircuits is connected in series, whereby the resistance between the terminals of the electrically heatable catalytic converter is effectively raised.
