Jr-Ss Electronic Overload Relay

Product Name: Jr-Ss Electronic Overload Relay Model NO.: JR-SS Type: Electric Parameter Relay Size: Miniature Number of Pole: 1 Electricity Type: Ac Phase: 3 Usage: Household Appliances Relay Theory: Thermal Relay Trademark: ELECAL Transport Package: Carton Origin: Wenzhou Product Description 1.ApplicationJR-SS electronic overload relay is suitable for AC 50/60Hz, voltage up to 600VAC and currentup to 60A. It is used as overload and phase loss protection, independently adjustable startingand trip delay, visual current setting aid and trip indication, fail safe protection (N type) andelectronic shear pin function. The product conforms to IEC60947-1 standard.2.SpecificationTypeJR-SSCurrent range05)0.5-5A(scale 6.5A)30)3-30A(scale 35A)60)5-60A(scale 70A)Rated voltage600VAC,50/60HzOperation settingD-TIME0.2-30secondsO-TIME0.2-10secondsAccuracyCurrent±10%Time±15% of max.time set valueTime characteristicsDefinite timeControl voltage220)Voltage free(90~260)VAC,50/60Hz440)Voltage free(320~480)VAC,50/60HzOther voltage optional.Current sensing2 CTsOutput contactsContactsSPDT 3A/250VAC ResistiveConditionN TypeNormally energized:95-| |-98closedR TypeNormally De-energized:95-|/|-98closedResetManual or remote electrical by interrupting supplyEnvironmentTemp.
