Project Description
Circuit breaker for DC
The BHACB1-DC module consists of 3 security machines that are independent from each other. Each security machine can be configured to a DC (DC) between 0.5A and 30A in steps of 0,5 A. In addition, the current / time characteristic can be set over 5 points.
The module was designed in a way that allows the connection to the network via the Ethernet Gateway BHEG1.
As soon as the BHACB1-DC is connected to the Ethernet Gateway, the configuration of the fuses is supported by a graphic web interface.
