| Long Description | TeSys LR97D electronic overcurrent relay, 38A/690V, to be supplied with 100-120V AC, for protection of motors with a rated current 20-34A. It provides 3 dials to adjust the protection, LOAD (20-38A) for the overcurrent level, O-TIME (0.3-10sec) for the acceptable duration of the overcurrent, D-TIME (0.5-30sec) for the starting duration. In addition, the device trips when the current is higher than 3 x LOAD during more than 0.5sec in steady state and if there is a missing phase during more than 3sec. The settings include selectors for 1-phase/3-phase motors and manual/automatic reset, and the device has a reset button, a test/stop button, 2 LED indicators (Run/Trip), 2 auxiliary contacts 1NO/NC for fault signalling. Settings can be locked by sealing the transparent cover. For direct attachement to the bottom terminals of a 3-pole contactor LC1D25-D38, with screw clamp terminals on bottom, the separate mounting from the contactor is possible using the terminal block LAD7B106 (to be ordered separately). Multi-standards certified (IEC, UL, CSA, CCC, EAC), compliant RoHs/Reach. | THE INDUSTRY'S MOST POPULAR FUSE FOR MOTOR CIRCUIT PROTECTION. Tri-Onic SmartSpot TR fuses now provide a visual open fuse indicator. With advanced material technology added to the existing product line the TR current limiting time delay fuses are engineered for overcurrent protection of motors and transformers, service entrance equipment, feeder and branch circuits. Tri-onic's proven time delay characteristic safely handles harmless starting currents and inrush currents associated with today's motors and transformers. | The KRN1000 series paperless recorders feature 5.6-inch TFT color LCD (640×480) touchscreen displays with excellent visibility and intuitive control interface. The recorders can process 27 types of input with high-speed sampling rate up to 25 ms and recording cycle between 1 to 3600 s. Various communication methods are supported along with high capacity storage memory (internal/external). Users can also cycle between 9 different graph types, depending on the required application. The series is available in 4, 8, 12, 16 input channel models with various input/output options. |
