Semi\u2011auto \u00b7 Shift mechanism<\/div>\n

MCB Semi\u2011Automatic Thermal Trip Calibration Bench Type\u2011A<\/h1>\n

The MCB calibration bench (Type A) is purposely built to perform effective testing and calibration of miniature circuit breakers (MCB). There is a unique shifting mechanism that accommodates a range of different circuit breaker types, allowing you to carry out precise thermal trip calibrations. There is an easy-to-use interface which allows the user to set test parameters (i.e. overload current multipliers, trip time Windows) very easily as well as view real-time results. this unit is built for both laboratory and field applications, making it an important device for enhancing the efficiency and accuracy of testing for circuit breakers. The robust construction and standardisation (according to IEC 60898-1) of this equipment makes it a must have for either a MCB manufacturer or technician.<\/p>\n

The bench is designed for semi-automatic operation. The operator loads an MCB into the test system, selects a product recipe on the HMI, and presses the start button. The test system will then apply the overload current as programmed (ie. 1.13\u00d7, 1.45\u00d7 In), take the trip time, compare that trip time to the IEC window of time, and show the results. An optional integrated calibration tool allows the operator to physically adjust the bimetal screw while watching the trip time live, re-testing until the trip time falls within specification. It will also allow for quick changeover of other families of MCBs with minimal complexity for tooling changes and is ideal for QC laboratories, production sampling, and R&D activities.<\/p>\n

What is an MCB Semi\u2011Automatic Thermal Trip Calibration Bench Type\u2011A?<\/h2>\n

The MCB semi-automatic thermal trip calibration bench Type A is a specialized testing device used to calibrate the overload (thermal) trip feature of miniature circuit breakers. The Type A bench is semi-automated, which allows the current to be applied and the trip time to be measured automatically, but the operator is responsible for loading\/unloading the circuit breakers and (if required) adjusting the bimetallic heater. The Type A bench has a mechanical shifting function for the test fixture, which allows the test fixture to be adjusted to accommodate all miniature circuit breaker designs (e.g., 1P\/2P\/3P\/4P; multiple current ratings) without changing the electrical connections. The Type A bench also has a digital display that shows real-time trip time, pass\/fail status and the number of tests previously completed; it meets the requirements of the IEC 60898-1 standard for over-current protection verification. The Type A Calibration Bench is an ideal solution for laboratory applications, production quality assurance and field service applications where flexibility and moderate throughput are required. As a non-standard custom solution, we will modify the shift mechanism and test fixture to suit your specific series of MCB.<\/p>\n

Shift mechanism for flexible MCB compatibility<\/h4>\n

The test contact shift mechanism (Type A), unlike a permanent fixture, permits lateral movement of test contacts to accommodate different terminal pitch configurations of MCBs. The benefit is that any given test bench can test numerous MCB variations with no manual rewiring or adapter modification, making it very useful for laboratories performing multiple families of products.<\/p>\n<\/p><\/div>\n

\n

Semi\u2011automation boosts consistency & throughput<\/h4>\n

Manual calibration relies on the stopwatch and reaction times of operators to get accurate results. With Type A, you have an automatic way to apply current, detect a trip and measure time where there is no chance for human error \u2013 all you have to do is load up your MCB, hit the start button and read your result, providing you with an average reduction of 50 \u2013 70% in unit test times when compared to using manual benches.<\/p>\n<\/p><\/div>\n

\n

Real\u2011time trip time monitoring for precise adjustment<\/h4>\n

For every adjustment that is made to the bimetal screw during calibration, the operator is able to view the real-time trip time displayed on the bench. This allows for immediate feedback based upon the adjustments made. There is no limitation on the number of attempts needed to achieve the target range (-20%), as all re-testing will take place at the bench.<\/p>\n<\/p><\/div>\n

\n

Portable & robust for field or lab use<\/h4>\n

Type\u2010A’s strong and durable compact construction provides it with significant advantages for quality assurance laboratories as well as field use. Users can opt for an optional carry case and\/or battery-powered operation (for storing data).<\/p>\n<\/p><\/div>\n<\/p><\/div>\n

Customer Success Story \u2013 Electrical Testing Laboratory<\/h3>\n

There was a need to calibrate fifteen different circuit breaker models from multiple manufacturers using an independent laboratory. Each of the manual test fixtures needed to be wired for each of these fifteen circuit breakers, a task which took approximately ten minutes for each circuit breaker change. Benlong used a semi-automated thermal trip calibration bench with a shift mechanism, nevertheless the changeover time dropped to thirty seconds, and the accuracy of the test improved. After six months of use, the following results were produced:<\/p>\n

\n
15 models<\/strong> Supported on one bench<\/div>\n
50%<\/strong> Reduction in calibration time per batch<\/div>\n
0%<\/strong> Operator errors in trip time recording<\/div>\n<\/p><\/div>\n

The bench paid for itself in 8 months and became the lab\u2019s primary MCB calibration tool.<\/p>\n<\/p><\/div>\n
