    1P-120

    Transient/Surge Absorber
    1-Phase

    Transient/Surge Absorbers (TSAs) provide system designers with a cost effective method of protecting sensitive electrical and electronic equipment from damage caused by switching transients, coil and motor backlash, and near miss lightning strikes. There are 3 models available: single-phase (1P), 3-phase delta 3-wire (3PD), or 3-phase wye 4-wire (3PY). Each model is available to cover nominal AC voltages of 120, 208, 240 and 480. TSAs are designed using a ceramic and metal oxide technique which causes the resistance of the device to decrease abruptly if the rated voltage is exceeded. Voltage ranges are achieved by varying the types of oxide used in each model. Resistance changes are very fast, requiring less than 50 nanoseconds after the threshold voltage is exceeded. All models can repeatedly absorb in excess of 24,000 watt spikes without damage.

    295-120

    Capacitor Trip Device
    120 VAC

    The Model 295 Capacitor Trip Device is used to trip circuit breakers requiring an AC voltage, by using the stored energy in a capacitor. The capacitor is kept at full charge during normal operation by a half-wave silicon rectifier which draws its energy from the power line. When completely discharged, the Model 295 draws approximately 10 amps from the line in the first half cycle, 3 amps the second half cycle and 1 amp from the third. Continuous current required to keep the capacitor charged is less than 5 milliamps. The capacitor holds sufficient charge to trip the breaker for at least 12 seconds after the charging voltage is removed. However, on most fault conditions, some voltage is still present, so the Model 295 is designed so that 65% of normal voltage gives sufficient charge to trip the breaker. A low-energy lamp, connected in parallel with the storage capacitor, gives a visual indication when the voltage charge is 85 volts or more on the 120V version and 170 volts or more on the 240V version.
