Sprecher + Schuh CEP7 electronic overload with adjustable AMP ranges from 1 to 100 AMPS (must specify frame size and AMP range above) and directly mounts to the CA7 series of contactors. These solid state overloads come with phase loss protection, manual or automatic reset (for remote resetting option) and class selection from Class 10 to Class 30 (tripping times from 10 seconds up to 30 seconds). The CEP7 overload comes in three sizes with AMP ranges from 1 to 27 AMPS for the 9 to 23 AMP contactors, 5 to 45 AMPS for the 20 to 43 AMP contactors and 18 to 90 AMPS for the 60 through 85 AMP contactors.

Thermal or bimetallic overload relays typically have a small current adjustment range of 1.5:1 meaning that the maximum setting is generally 1.5 times the lower setting. The CEP7 caused the industry to take note of the flexibility when it first introduced a 3.2:1 adjustment ratio. A wider adjustment range is the primary reason the industry has been turning to more specifications calling for electronic overload relay protection over thermal overload relays. Sprecher + Schuh’s CEP7 overload relay is capable of adjustment to a maximum of five times the minimum set current, which dramatically reduces the number of units required on-hand to cover the full range of current settings up to 200 amperes.
