• Polymer PTC body, small compact size
• Resettable switching device
• Low current loss due to 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, e.g. 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.

The RUEF-series is suitable for use in many general electronic applications. It completes the RXEF-series (see E1221) with its small form, low resistance and limiting no-damage current.
