This is a hybrid bench to integrate MCCB over current tripping as well as temperature rise testing as per IEC 60947 and custom based requirements. In addition, temperature rise module helps monitor the temperature rise in various parts of the system in rated current as well as over-current mode. The system comes with user interface software configured in NI LabVIEW making testing of MCCBs complete where thermal curves with current as well as temperature rise can be plotted on a PC. The test jig is flexible such that different MCCBs can be tested and compared for their performance. The bench integrates temperature data logger system with k type Cr-Al temperature probes with both digital and ON-PC online display of temperatures..
This bench is built to test MCCB instantaneous tripping (also known as Short Circuit or Magnetic tripping) as per IEC 60947-2 Cl 8.3.3 and custom based requirements. A speciality of the system is that it includes differently designed systems for two different current ranges (Smaller range for currents < 2000 A and higher range for currents >2000 A) thus ensuring equal reliability, accuracy and regulation for both low current and higher current MCCBs. Specially designed custom built jigs are able to accommodate different types of MCCBs enabling the user to test all kinds of miniature circuit breakers on a single test bench. In addition, the system can be made such that it covers the entire range of MCCBs for production floors producing all ratings of MCCB.
The SCR ELEKTRONIKS Millivolt Drop Tester is an industry acclaimed product. MVDT has a specially built constant current source (current generator) up to 400A (depending on model) and a dedicated PLC to store test parameters (in automatic models), perform test procedure, make the millivolt drop & junction resistance measurements and store test results, that can be retrieved later or downloaded to PC. PC based TestWare can display the test results & export those to Office, HTML, Printer or PDF. The manual models consist of the constant current source, digital ammeter and a digital millivolt meter with 3 ranges.
Needle Flame Test Apparatus is the commonly used equipment for testing solid insulating material for fire hazard testing. This test apparatus is covered in IEC 60695-11-5 and commonly referred for various devices in many standards such as IEC 60335-1, IEC 60695-11-3, IEC 60695-11-10, IEC 60695-2-2, IEC 60598-1, IEC 60512-20-1, IEC 60749-32, ASTM D635-18, UL 94, UL 1694, BS 6458, and IS 11000-2-2.
SCR Elektroniks has developed a PC based motor starter test bench to check the continuity of the motor starter against over current. The bench is customizable for 3, 5, 6 and 12 stations.
The SCR Elektroniks production test bench for factory testing of contactors is used to test a variety of electrical parameters and compliance verification for the contactors. This single bench conducts nearly all of the electrical tests that are relevant to the contactor prescribed by various versions of IEC 60947. The tests are conducted in a sequential manner on more than one station at a time thus testing multiple contactors simultaneously.
