IEC 60947\u20112 \u00b7 Full\u2011process automation<\/div>\n

Fully Automatic MCCB Production Line for Medium\u2011to\u2011Large Frames<\/h1>\n

This MCCB automated production line is designed to produce moulded case circuit breakers (MCCBs) with medium or large currents in high volumes. The production line operates as a single continuous production process; hence, there are four integrated production processes within this single system, with automated riveting, torque calibration, testing of tripping characteristics, and deep MES integration in one continuous production process for every unit manufactured. Servo-driven tooling provides exacting precision in the alignment of arc chutes and contact systems during their fitting and operation; and the deep MES integration provides sufficient tracking of all parameters for each unit manufactured, thereby providing complete compliance with IEC 60947-2 and GB 14048.2 standards.<\/p>\n

There are several important features to take into account including complete automation of every processing step (case loading, riveting, torque setting, electrical testing with no manual handoff), high accuracy servo drive, ETU digital calibration with Modbus communication confirmation, and quick change tooling for multiple frame sizes. The line will allow tests to be completed on approximately 30 seconds per part (depending on the rated current). In short, the line allows MCCB manufacturers to prepare for Industry 4.0, assure quality, and reduce labor costs.<\/p>\n

What is an MCCB Automatic Production Line?<\/h2>\n

A produced wholly automatic MCCB assembly line is a complete system for producing molded case circuit breakers that integrates all processes (assembly, riveting, torque measurement, and electrical testing) into one continuous stream of production. A fully automated MCCB production line is different from a semi-auto or automated production line since it uses servo-controlled actuators and rigid tooling to provide consistent forces\/positions, which is a key factor in high-current applications, as arc chute alignment and contact pressure have a direct effect on the breaking capacity of the MCCB. This production line utilizes automated loading of cases, riveting of molded-case structure, torque-controlled fastening of operating mechanism screws, and inline ETU calibration with curve validation. All test data generated (torque levels, trip times, contact resistances) will be recorded against the unit’s serial number via MES. Since this is a custom non-standard solution, we can customize the assisted factory line to accommodate your frame sizes (100A-1600A), expected production volume, and specific ETU communication protocols.<\/p>\n

Principaux avantages techniques<\/h2>\n
\n
\n

Full\u2011process automation eliminates manual bottlenecks<\/h4>\n

All stations use a conveyor to move products from case feed into the final ETU calibration with no manual handling between process steps. This reduces labor dependency by as much as 70%, while eliminating quality inconsistencies resulting from operator fatigue.<\/p>\n<\/p><\/div>\n

\n

Servo\u2011driven precision for high\u2011current components<\/h4>\n

Alignment of arc chutes and assembly of the contact system require the accurate positioning to within a micron. To achieve this, programmable force and positioning are accomplished through the use of servo-controlled actuators. As such, all MCCBs will have the same breaking capacity consistently.<\/p>\n<\/p><\/div>\n

\n

ETU digital calibration with communication verification<\/h4>\n

Automated ETU calibration stations are a component of the line that can create faults and (simulate) measure output currents (L-S I-G curves) and verify Modbus communication. Each trip curve is recorded and compared against IEC 60947-2 standards for automatic pass\/fail sorting.<\/p>\n<\/p><\/div>\n

\n

Full MES traceability for quality audits<\/h4>\n

Each unit is recorded by the following parameters as per each serial number: torque values, riveting forces, trip times and contact resistance. This also enables the export to your MES granting you with total traceability to ISO 9001 and\/or customer audits.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n

Customer Success Story \u2013 Global MCCB Manufacturer<\/h3>\n

A major manufacturing firm of mold breakers sought to produce more than 225 A and 630 A frame MCCB in accordance with IEC 60947-2. The semi-automatic line they currently were using had unreliable torque measurements and no traceable production processes. Benlong offered to provide them with an Fully Automated MCCB Production Line with ETU Calibration and MES Integration for 6 months and here are the results of that production:<\/p>\n

\n
30 sec\/pc<\/strong> Test efficiency (manual was 90 sec)<\/div>\n
99.5%<\/strong> First\u2011pass yield (up from 94%)<\/div>\n
100%<\/strong> Traceability for all production parameters<\/div>\n<\/p><\/div>\n

The line paid for itself in 14 months and enabled the customer to pass a major utility audit with full data records.<\/p>\n<\/p><\/div>\n
