What is a capacitor trip device?

Capacitor trip devices are commonly used in switchgear to provide trip circuit power and to provide voltage sag ride through capability for digital relays. CTD is not commonly used for closing applications as it is expected that the normal control power will be available when closing is desired.

What is auto-charged capacitor trip device?

Auto-Charged Capacitor Trip Device Self-contained standby power source Maintains full operating voltage for a minimum of two days high speed capacitor-type circuit breaker tripping unit.

How does a 295 capacitor trip device work?

Discharge Manually or with a Control Device The Model 295 Capacitor Trip Device is used to trip circuit breakers 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.

How long does it take a breaker to trip a capacitor?

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.

What should I do if my 295 capacitor trip device fails?

Verify that power is present, and check all fuses. Should problems persist, contact the factory at 800-862-2875 for assistance. The Model 295 Capacitor Trip Device is warranted to be free from defects in materials and workmanship for one year. Should this device fail to operate, we will repair or replace it for one year from the date of purchase.

What is the warranty on the model 295 capacitor trip device?

The Model 295 Capacitor Trip Device is warranted to be free from defects in materials and workmanship for one year. Should this device fail to operate, we will repair or replace it for one year from the date of purchase.
