Features
• Polymer PTC body, small compact size • Resettable switching device • Low current loss due to a low resistance in normal use • Protection against overcurrent and short circuit The PolySwitch device is a resettable switching device made from a polymer blend. The mode of action is based on the PTC effect. In standard use, the resistance of the PolySwitch device is very low so that only a small power loss arises. In the event of an error, short-circuit or overcurrent, the resistance value of this device increases and protects the equipment. After eliminating the error and switching off the supply voltage, the PolySwitch device quickly returns to a low impedance state.
Application
• Power supplies, motor amplifiers up to a maximum voltage of 60Vrms
