CEP7 Interchangeability Of Single-Phase And Three-Phase Overload Relays
Can you interchange or swap out a single-phase CEP7S-EE__ overload relay with a three-phase CEP7-ED1__/CEP7-EE__ solid-state overload relay? If I wire or loop the single phase power source through the legs of the CEP7 Three-phase solid state relay, will this configuration protect the motor?
CEP9 Overload Relay Device Modes And Dial Functions
What are the different device modes and the rotary dial functions of the CEP9 Electronic Overload Relay? The CEP9 Electronic Overload Relay has four device modes to validate configuration of the device and limit when a user can configure the overload relay, perform a firmware update, and issue commands.
What is the heat dissipation rate of the CEP7 overload relays? How does it compare to other types of overload relays? Sprecher + Schuh CEP7-ED_ and CEP7(S)-EE_ overload relays dissipate heat more efficiently than traditional thermal or eutectic alloy overload relays.
What happens when the test button is depressed on the CEP7-ED1/EE overload relays? Will activating the test button show up as a trip on the overload relay? Do the CT7N and CT8 Overload Relays react in the same manner?
One of the outstanding features of IEC type overload relays is protection of three phase motors in the event of a single phase condition; otherwise known as “open phase” or “phase failure “ in one of the motor leads.
