Five load ranges are available from 1 ampere minimum to 450 amperes maximum. Range setting is adjustable in a ratio of 7 to 1. Repeat accuracy is plus or minus 2% with maximum differen tial of 15%. A neon indicating light is used to show if relay is ener gized.

Multiply current to be monitored by current transformer primary turns. Standard relay operation provides pick up in 50 milli-seconds, drop out 16 milli-seconds after deener gizing. Time delay pickup for cur rent values between 85-100% of setting can be provided with ex ternal capacitance as shown below.
