The Model CTD (Capacitor Trip Devices) are designed to provide a source of energy for a circuit breaker or switch to trip during a loss of normal AC or DC power. There are 2 types, Model CTD-1 (for 120V, 330 UF), or Model CTD-2 (for 120V, 1500 UF).
Customer ServiceWith DC control voltage, when sensitive trip or close contacts exist, it is recommended to limit capacitance on the DC control wiring to prevent unwanted trip or close operation during accidental control circuit ground fault.
Customer ServiceAnd how does a bad capacitor cause your circuit breaker to trip? The window AC''s capacitor gives an extra "jolt" of energy to the compressor and fan motor to start up. If the capacitor goes bad, the compressor or fan motor will stall in place and overdraw amperage from your home''s electrical system – causing the breaker to trip.

Customer ServiceSo that may explain why you sometimes get a trip on startup, and once it actually starts, it behaves without tripping. It''s possible something is wrong with the internal electronics that''s causing a trip after the device is on. It could be a capacitor that''s charged, it could be a solder joint warmed up and is arcing across another joint, etc

The capacitor is kept at full charge during normal operation by a half-wave silicon rectifier which draws its energy from the power line.
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.
This question often arises, and the answer is usually no for the following reasons: • Grounded capacitor banks can interfere with a facilities ground fault protection system and cause the entire facility to lose power (main breaker trip).
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.
