Arrangement for electrical switchgear as thermal overload actuator, has thermo sensitive element for breaking electric circuit and has ohmic heating resistance lying in electric circuit
摘要
<p>The arrangement has a thermo sensitive element (100) for breaking an electric circuit and has an ohmic heating resistance lying in the electric circuit. A heat quantity, which acts on the thermo sensitive element and causes the circuit break, is generated from the heat resistances in predetermined manner. The heating resistance consists of a chargeable faulty wiring configured between a main resistance (R) and other resistances (R2).</p>
