<p>The power resistance (1) has at least one resistance element (5) as a spiral (6) with two electrical connections (13,14) at the power line (15,16). A short circuit protection (2) has two electrodes (24,25) in a common housing (20), electrically linked to the connections, forming a spark gap (26) between them. They form a short circuit when a voltage overload breaches a threshold.</p> |
