A: Steps

1. Check for the circuit breaker information in specification or installation. If it is not shown, you can calculate it according to the following steps.

2. Enter MEAN WELL Expo with following LINK.  https://expo.meanwell.com/cbs/index.html

3. Fill in the values of inrush current , T50(Note 3) and Rated AC current that is defined in the specification accordingly.

4. The result must be verified onsite.

B: Calculation demonstration

Taking HLG-600H as an example, the inrush current is 70A, the T50 is 1000us, and the AC current under 230VAC is 3.3A. The result will be shown after the finishing of parameter entering.

The first column is the model of the circuit breaker, the first code is the classification of the circuit breaker, and the second code is the rated current. For example, B10 means B type with 10A rated current.
The second column indicates the maximum number of HLG-600Hs that can be connected to one circuit breaker. For example, if B10 is selected, only one HLG-600H can be connected, and if D16 is selected, four HLG-600Hs can be connected.

To operate with MEAN WELL power supplies, a MCB with a tripping characteristic “C” or “D” is recommended.(In : Rated Current)

Note: 1. MCB data adopts with ABB’s product, relevant data is only for reference. Different set-up may result difference.

          2. Please contact MEAN WELL KULON technicians for product without T50 information.

          3. T50 is the time width of 50% of the inrush current value.
