Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

The Eaton PKZM01-0.63 is a compact motor protective circuit breaker that stands out for its precise thermal-magnetic protection in a 45 mm-wide DIN-rail housing. Unlike generic MCBs, it offers adjustable overload release from 0.4 A to 0.63 A, making it ideal for protecting small motors and transformers where exact current matching is critical.

Highlights

  • 3-pole switching for three-phase circuits up to 690 V AC
  • Thermal overload and magnetic short-circuit release in one device
  • Adjustable overload setting range: 0.4 – 0.63 A
  • High short-circuit breaking capacity of 50 kA at 400 V
  • Screw terminals for secure wiring, DIN rail or screw mounting

In daily use

Install the PKZM01-0.63 on a standard 35 mm DIN rail and set the overload dial to the motor's full-load current. The thermal release responds to sustained overcurrents, while the magnetic trip reacts instantly to short circuits at approximately 14 times the rated current. The IP20 terminal protection and wide operating temperature range (-25 to +55 °C) suit most industrial control panels.
