Devendran asks about provision of a DIN standard reference number for MCBs. His question has been answered by Schneider Electric (Theme – Distribution Equipment):
Question: For MCBs constructional dimensions - can you please provide the relevant DIN standard reference, so that we can buy these standard designs for our design review?
Answer: This question does not relate to a specific Schneider Electric product, so we would recommend that a consultant be involved.
However, the general requirements needed to choose a suitable circuit breaker are as follows:
* System type
* Voltage and frequency
* Thermal rating of circuit
* Short circuit rating of circuit
* Load characteristics
* Mounting position and enclosure type
* Possible country of destination
* The appropriate standard.
