Cooper Power Systems by Eaton
Type L
|
System Voltage: 120, 120/240, 120/240 volts Y
Rating: 175 volts*
* An arrester rating represents the maximum line-to-ground voltage to which the arrester should be subjected. Since surge arresters are inherently sensitive to overvoltages, they should never be subjected to 60 Hz voltages above their rated voltage, even during momentary abnormal conditions. If such a condition is likely, a special system study may be necessary, and a higher rated arrester may be required.
Type L secondary arresters protect street-lighting controls, low-voltage relays, railroad-signal circuits and circuits used for fire alarms, remote metering and airport lighting. They are applicable for voltages up to 175 Vac, or 125 Vdc and are designed for indoor mounting.
