RXEF

• Protects devices from overloading and short-circuiting
• Power supplies, motor amplifiers up to a maximum voltage of 60Veff
• Polymer PTC body, small compact size
• Resettable switching device
• Low current loss due to a low resistance in normal use

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.
