Overload relays are designed to open the circuit when the current becomes 115 percent to 125 percent of the motor full load current. T. Thermal overload relays trip faster when located in a cool area than in a warm area. F. Many bimetal strip type overload relays can be set for either manual or automatic reset. T.

NettetThe first group of PTC thermistors is comprised of silistors, which use silicon as the semiconducting material. They are used as PTC temperature sensors for their linear characteristic. The second group is the switching type PTC thermistor. The switching type PTC thermistor has a highly nonlinear resistance-temperature curve. Nettet2) It is absolutely quiet in operation. 3) The current is not continually applied to the coils of the relay, thus conserving energy. 4) The circuit continuity is maintained during a power failure. The neutral wire can be_______. White or light grey. Main or subassembly line conveyors use sequence control. True.
