WebThe E3 Overload Relay offers underload trip and warning settings adjustable from 10…100% FLA. The trip function also includes a trip delay time with a range of 0.1…25.0 seconds. Over-temperature Protection The E3 Plus Overload Relay provides motor over-temperature protection with the added provisions for terminating and monitoring WebMay 9, 2002 · When the hot wire is connected directly to ground, there is minimal resistance in the circuit, so the voltage pushes a huge amount of charge through the wire. If this continues, the wires can overheat and start a fire. The circuit breaker's job is to cut off the circuit whenever the current jumps above a safe level.
