Specification Brand : Mallory BulletPoint : Price For: Each Transducer Function: Alarm Tones: Continuous Supply Voltage Min: 16V Supply Voltage Max: 28V Operating Current Max: 40mA Sound Level SPL: 85dBA Sound Level Distance: 609.6mm Resonant Frequency: 2.9kHz Product Range: - BulletPoint1 : Descriptions:This is a mini split base current transformer; it's the smallest one compared to the similar products (output 100MA). Fully enclosed, good mechanical properties and environmental resistance, strong voltage isolation capability, safety and reliability. Used for energy meter in special; AC 220v, 380v power supply can both be applied BulletPoint2 : Model: PZCT-02 Environment temperature: -40℃~+85℃ Relative humidity: ≤ 90%(40℃) Working frequency: 50Hz~60Hz Insulation endurance grade: B grade (130℃) Insulation resistance: >1000MΩ normally Dielectric strength: can afford power frequency 1000V/1minute Flame resistance: Conform to UL94-Vo grade Internal resistance: 10Ω Measuring range: 0-100A BulletPoint3 : Application:1. The current transformer is used for energy meter in special; AC 220v, 380v power supply can both be applied.2. When you fix the energy meter, you don't need to cut off the power if you use this product. BulletPoint4 : Note:1. The CT primary should be connected in series with the test current loop, the secondary should be as work in the short-circuit state.2. The secondary circuit is not allowed open circuit, so please do not install fuse BulletPoint5 : Features:This is a mini split base current transformer; it's the smallest one compared to the similar products (output 100MA). The diameter of inner hole is 16mm, the accuracy is ≤0.5 grade,Using snap joint structure, it can be fixed to the cable directly through nylon ties.Built-in input coil; small and light, easy to install.Fully enclosed, good mechanical properties and environmental resistance, strong voltage isolation capability, safety and reliability Color : Multiple colors CurrentRating : 100 amps ExternallyAssignedProductIdentifier : 9497371132309 ExternallyAssignedProductIdentifier1 : 0642008231552 ExternallyAssignedProductIdentifier2 : 642008231552 FinishType : Finish IncludedComponents : inc ItemName : Transducer, Piezo, Alarm, Continuous, 16 V, 28 V, 40 mA, 85 dBA ItemPackageDimensions_Height : 5.08 centimeters ItemPackageDimensions_Length : 22.86 centimeters ItemPackageDimensions_Width : 15.24 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : piezo-transducers Manufacturer : MALLORY Material : copper MaximumFrequency : 60 hertz MinimumFrequency : 50 hertz ModelNumber : SCE028MD3CTB NumberOfItems : 1 PartNumber : SCE028MD3CTB PowerSourceType : Corded Electric ProductDescription : SCE028MD3CTB - ProductSiteLaunchDate : 2015-08-20T06:51:34.927Z Size : Small SpecificationMet : RoHS Style : Wire Collated UnitCount : 1 UnspscCode : 60141000
