MCCB Yarı Otomatik Yüksek Gerilim Test Tezgahı
Semi‑automatic MCCB high voltage test bench covers 125A‑1250A (7 frame sizes) in one platform. Quick‑clamp system, OK/NG red/green indicator lights, touchscreen HMI, real‑time display. Reduces equipment investment by up to 70%, changeover time to under 5 minutes. IEC 60947‑2 compliant hi‑pot testing.
Semi‑Automatic MCCB High Voltage Withstand Test Bench
The MCCB semi-automatic testing bench for withstand voltage (dielectric strength) testing of MCCBs was designed with the capability to accommodate multiple frame sizes within one structure using a unique multiple frame design providing significant savings in equipment and time by using one platform with the ability to test seven different frame sizes of MCCBs; from 125/250A through 400/630/800/1000/1250A individually tested within one test setup. The 4 quick clamping systems and user friendly touch screen will allow the operator to perform each test cycle quickly. The results of all tests are displayed back to the operator using OK/NG (Pass/Fail) indications (Green for Pass/Red for Fail) eliminating guesswork and increasing throughput on high volume production lines. The Digital Display/HMI Panel provide real time display of test parameters and results to capture data accurately during every withstand voltage test cycle; ensuring every MCCB produced out of production has a reliable quality assurance.

What Problems Does This Test Bench Solve?
There are three significant issues that arise when using traditional MCCB high voltage testing: there needs to be separate testers for each frame size (cost of equipment), there are significant waiting periods during switch-overs (loss of production), and there can be multiple interpretations of test results (operator-error). The semi-automated bench solves all three challenges: one bench will cover 125A through to 1250A (7 frame sizes), switch-over time is only minutes due to a quick-clamp system, and OK/NG (green/red) indicators provide immediate and unambiguous results. The bench performs dielectric strength (hi-pot) testing (IEC 60947-2) at high voltage – Phase-to-Phase and Phase-to-Ground, while measuring leakage current. This bench is perfect for use in MCCB manufacturing lines, QC laboratories, and for receiving incoming inspections.
Available in several different frame sizes, including 125A, 250A, 400A, 630A, 800A, 1000A and 1250A. This will save you as much as 70% of your overall investment on electrical equipment.
Changeover between frame sizes takes minutes, not hours – maximizes production uptime.
Green light for pass, red light for fail – eliminates operator interpretation errors.
Live test parameters and results – full traceability for quality audits.

Core Customer Benefits – Why Manufacturers Choose This Bench
Benefit 1: 70% lower capital investment
By using one bench to test all 125A-1250A MCCBs instead of having 7 testers (one for each frame size) we can achieve a maximum reduction of equipment costs by 70% and also free up a significant amount of factory floor space.
Benefit 2: 80% faster changeover
Changing frame sizes manually takes 15 to 30 minutes. By using the Quick-Change Clamp System, we can reduce this time to less than five minutes and, as a result, we will save hours of testing time every week.
Benefit 3: Zero interpretation errors
Operators will not need to check digital displays and determine if they passed or failed anymore, because OK (green) / NG (red) lights provide immediate, clear answers — eliminating variation between batches.
Benefit 4: Real‑time data for quality audits
HMI shows live test voltage and leakage current. All test parameters/results may be logged and exported, allowing full traceability for ISO 9001 and IEC audits.
Customer Success – How One Manufacturer Saved $150,000 in Test Equipment
After switching from using 6 dedicated hi-pot testers for differing frame sizes (125A – 1250A) to using this semi-automated high voltage tester (which covers all sizes), the MCCB manufacturer achieved:
The bench paid for itself in 6 months and freed up 15 m² of factory floor space.

Sıkça Sorulan Sorular
When the MCCB successfully passes the high voltage withstand test (leakage current is less than the set limit), the indicator will have a green light. If it fails (leakage > the set limit), then it will show a red light and indicate either excess leakage or a dielectric breakdown. As such, the result is instantaneous and eliminates any operator error in interpreting the results.
The standard bench comes with quick-change adapters for 7 frame sizes: 125 A, 250 A, 400 A, 630 A, 800 A 1000A, and 1250A. You can create custom adapters to fit additional frame sizes.
The fast-, clamp system enables a change of table type to be done in less than five minutes compared to the traditional 15 to 30 minutes.
Correct. Live test parameters such as voltage, leakage current and duration will be displayed on HMI (Human Machine Interface). Optional recording of these test values can be recorded on USB or MES (Manufacturers Embedded System) interface for complete traceability.
An interlock door encloses the testing area, meaning that high voltage cannot be operated while the interlock door is opened. There is also an emergency stop button provided.
