Typical temperature sensitivity characteristics
A special feature of the MK1 series is that the switch is a temperature-sensitive switch. In normal operation and loads up to nominal current, self-heating of the switch is extremely low. Therefore the lowering of the switching temperature caused by self-heating will be within the NorminalSwitchingTemperature tolerance.

The Product Sells Point
ÃŽ Compact & Pressure Stable: Ideal for installation in limited space, very suitable for mounting into and onto windings
ÃŽ Safe, Reliable & Durable: Constant contact pressure over the whole temperature range; Very fast switching, therefore short arcing influence on the contacts
ÃŽ Temperature-sensitive: Reproducible Switching Temperature induced by mechanical unstressed and electrically unloaded bimetal disc
ÃŽ Fast: Excellent thermal coupling induced by a small-scaled, low-weighted switching device
ÃŽ Flexible: Extremely large assortment of lead-wires and solid wires available for connection
