Abstract
Disconnection or tripping device with thermal delay for a switch designed to protect networks and/or electric motors, in particular in low voltage networks, based on magnetic trip coils, characterized in that a thermal tripping coil is provided for the thermal trip or trip delay. Minus and four regulating resistors at least one of which is variable as a function of temperature; or alternatively, a variable regulation resistance depending on the temperature at least and two magnetic trip coils equipped with a common magnetic circuit.
