Detailed Description

Application Field: Typical temperature sensitivity characteristics A special feature of the MK1 series thermal protector 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 Compact & Pressure Stable: Ideal for installation in limited space, very suitable for mounting into and onto windings Safe, Reliable & Durable: Constant contact pressure over the whole temperature range; Very fast switching, therefore short arcing influence on the contacts Temperature-sensitive: Reproducible Switching Temperature induced by mechanical unstressed and electrically unloaded bimetal disc Fast: Excellent thermal coupling induced by a small-scaled, low-weighted switching device Flexible: Extremely large assortment of lead-wires and solid wires available for connection Key Specifications/Special Features NominalSwitchingTemperature: 60-200 Tolerance: (+/-)5K Reset Temperature: 30 +/- 15K Max. operating voltage: 500VAC 60VDC Working current(AC:COSφ=1.0):250VAC/2.5A500VAC/0.75A Working current(AC:COSφ=0.6):250VAC/1.6A500VAC/0.5A Shock resistance 10-60HZ: 100m/s2 Case pressure stability: 450N(45kg) Insulation voltage: 2KV Sectional area of lead wire: 0.35mm2
