Product Details | CIRCUIT BREAKER
5925-00-479-7909 A device with means other than fuses for automatically opening the circuit in which it is installed when the current varies from the predetermined value for which the device is set. May include provisions for manual operation. At least one set of contacts must be in series with the actuating element(s). A combination of semiconductor and passive devices may be used in lieu of contacts. For automatically operated items in which the actuating (tripping) element and contacts are not in series, see RELAY (as modified). For items which are operated both manually and automatically but the actuating elements and contact are not in series, see RELAY-SWITCH. Excludes CIRCUIT BREAKER BOX and magneto "breaker" assemblies. See also SWITCH (as modified); and CONTROLLER.

What Our Customers Say
Thank you very much for the excellent service and professional customer care.
The service was excellent. I can think of no improvements to date that you can make regarding internet sales.
The representative for WBParts was efficient & handled our request in a timely & professional manner.
Tried two other sources, neither of them responded, was all done online, never spoke to anyone.
The response is quick and the price is often very good. We are completely satisfied.
