Is our primary business quality control for CF4U Fuse Terminal Block?
- We admit it – we do take testing to a level beyond all reasonable expectations.
- There are 38 different tests that a Terminal Block has to undergo to pass Connectwell’s obsessively demanding quality assurance program.
- Many of these are tests mandated by International Standards, but our tests don’t always stop there.After several decades of observing the unpredictable abuses our products often have to withstand, Connectwell’s tests frequently go beyond the accepted norms.
- A case in point is our 96 hour Salt Spray testing of electroplated metal parts. Or our enhanced torque requirement norms for our screw terminals – a full 50% higher than recommended values.
We are our toughest critics:
- To ensure that the Terminals are tested with the right parameters, the testing conditions have to be accurate.
- In 2009 Underwriters Laboratories Inc. recognized the Connectwell Test Lab under the Witness Test Data Program.
- The Lab is also recognized under Witness Manufacturer’s Test program of IEC.
- Today the Connectwell Test Lab is recognized by major international testing bodies as a benchmark for customer-conducted testing.

How well you can correct also counts
- Of course we leave nothing to chance. Of course we are obsessive about testing. But no system is perfect.
- What makes one better than the rest is how well — and how quickly — you can take corrective action when something goes wrong.
- Our Automated Logistic centre enables complete traceability of materials, thereby enabling a robust batch management process.
- This is essential for implementing quality quarantines and product recalls, if they are ever needed.
Exceeding standards – and expectations for CF4U Fuse Terminal Block
- Over the last four decades, we have worked in every possible environment, from railways to critical process plants, from the oil and gas industry to power plants.
- And across all these applications, working with many different sets of customers, we have learnt one lesson we have taken to heart: no part, no component ever gets used exactly as it was designed to be used.
- Abuse in the field isn’t just a possibility it is inevitable over the life of any product.
- Which is why we go well beyond the benchmarks set by the world’s most respected standards in our product design and manufacture as well as our Quality Control.
