2322 66. 93034

•Fast response time for rapid protection
•Automatic resetting once overload is removed
•No contacts to burn out
•No thermal runaway
•Operates on DC or AC voltage
•Small size and rugged construction; see Component Outline drawing.

2322 66. 93034 can be easily damaged if excessive voltages are applied across their input terminals.

Simple and effective overload protection can be provided by 2322 66. 93034; see Typical connection of the PTC thermistor for digital multimeter protection drawing. Under normal conditions, the resistance of 2322 66. 93034 is low, so the test voltage will be measured by the instrument. Under an overload condition, the PTC thermistor will switch to its high-resistance state, absorbing the overload current and protecting the instrument. When the overload is removed, the PTC thermistor will return to its low-resistance state, ready to resume its protective function.
