Do Cutler-Hammer thermal overload relays fit to Centsable contactors?
Yes, the overload relay will work with Centsable contactors.
FAQ ID: 218
Do you sell contactors with 24 VAC or 24 VDC coils?
Yes, we now offer Fuji contactors with 24 VAC and 24 VDC coils.
FAQ ID: 219
Do the Cutler-Hammer overloads connect directly to Centsable contactors without going through a Cutler-Hammer mounting adapter?
Yes, the Cutler-Hammer overloads can connect directly to the Centsable contactors.
FAQ ID: 220
Can you stack multiple contactor top/front mounted auxiliary contacts on top of each other?
FAQ ID: 225
How do I determine the currents drawn by the contactor coils?
The contactor coil power requirements in VA are published in our specifications data. To determine the current, divide the VA by the voltage.
FAQ ID: 372
The lights brighten when my motor starts?
It is normal with some >220 vac circuits with neutrals that have lighting and motors on the same feeder. This is very brief though. If it is prolonged, > 1 second, this could mean that your neutral connection is loose. A loose neutral can lead to a voltage imbalance in the phases.

My Cutler Hammer starter always resets itself after a trip, how can I make it reset in manual only?
The dial on the overload unit should be moved to the “M” position. The two positions are “M” for manual and “A” for automatic trip release/reset.
FAQ ID: 841
What does trip free mean?
Refers to an overload unit or MSP that cannot be held on or started by the handle or pushbutton during a sustained overload. It is mostly a reference to the older style NEMA heater units that utilized a solder-pot. When the solder was in liquid-phase; the ratchet would not allow the spring to engage the reset. When the unit cooled down and the solder pot became solid again, the starter could be reset.
FAQ ID: 842
For single phase operation, can I use a smaller than rated contactor if I run the L conductor parallel through all three poles?
We do not recommend this practice. Do not exceed the rated capacity of what a single pole can handle. The operation will not close simultaneously which will allow a contact to take the entire load. This practice will lead to premature failures.
It is not uncommon to do this for greater reliability of the contactor, but the single pole specs must be met for all poles used.

Can the contactors/starters be used for DC motors?
FAQ ID: 924
Can I use a 3 pole starter for a single phase motor?
Yes, but use all three poles of the starter. Wire one of the incoming power lines through two of the poles in series per the manufacturer's instructions. Wire from the T_ terminal of one pole to the L_ terminal of the other pole.
FAQ ID: 1026
My motor is turned on and off frequently, or used for jogging duty. Should I derate (oversize) the contactor?
Yes. The published AC-3 ratings are for typical industrial continuous use applications. Jogging or frequent operation will significantly reduce the lifespan of an AC-3 rated contactor. For these applications, you should select a derated (oversized) contactor, and select the overload protection based on the motor's full load current.

Do the large Fuji "Odyssey" contactors/overloads ship with terminal lugs? If not, can I order them?
The Odyssey contactors/overloads do not come with terminal lugs. The contactors/overloads have a tab with a metric hole(with supplied nut and bolt) that is for the attachment of a 3rd party lug.
These lugs can be of varying types, but compression lugs give the best connection.
The different types of lugs can be purchased at a local electrical supply house, and often at Home Depot or Lowe's.
