The E300 Electronic Overload Relay provides overload protection through true RMS current measurement of the individual phase currents of the connected motor. The E300 Electronic Overload Relay includes a thermal memory circuit that is designed to approximate the thermal decay for a Trip Bimetallic thermal overload relays employ a U-shape bimetal strip associated with a current carrying heater coil.When an overload occurs, the heat will cause the bi-metal to deect and operate a control circuit contact. Different heaters give different trip points. In addition, most relays are adjustable over A300 contactors and overload relays. Motor rated operational powers and currents. The currents given below concern standard three-phase four-pole cage motors (1500 r.p.m. at 50 Hz 0.10 to 32 A - with thermal and electromagnetic protection Ics up to 50 kA MS116 manual motor starters Technical data. "thermal overload relay". The thermal overload relay does not provide short circuit protection as it takes sufficient time to open the contacts. Therefore, this type of relay is used in conjunction with fuses to provide overload and short circuit protection to the circuit. These relays have inverse time characteristics i.e Thermal overload relays are very reliable devices intended to protect motors, controllers and branch-circuit conductors against phase failures and overloads that cause excessive heating. The thermal overload relay has no power contacts and cannot disconnect the motor by itself. 3RU21 thermal overload relays up to 40 A have been designed to provide current-dependent protection for loads with normal starting against System integration. The overload relays have been matched to the contactors in the 3RT series both electrically and mechanically and can be integrated Motor InsightT Overload and Monitoring Relay.
